tember 1997, the Educational Testing Servicehosted a conferencein of Sam Messick on the occasion of his r e ~ e m e n as t an officer of ETS, a position he held for soke 30 years. It was a w o n d e r ~ event, l not only because the invi speakers and guests included many lea researchers in psycho1 andeducationalmeasurement but alsobecause al and professional connections to Sam. Held at the Chauncey Conference Center on the ETS campus, the conference gave Sam’s many friends and colleagues atETS an opportunity to p~ticipate in a milestone event and add their good wishes to those of the participants. This volume has much to offer the reader.It comprises a set of chapters based on papers presented at the conference. As befits a scientist of S a ’ s interests, the chapters cover a broad spectrum of topics in the sonalityandintellect,withparticularfocus on constructs, validty, and values. A number of authors seized the occasion to provide a reviewofwork in aparticularareaand to S estduections for ~ t h e r research.Some took a morecriticalstancedfocused on themore es in the fieldand indxated how theymightberesolved. tedtheir own leadingedgework.

One sad note at the conference was the fact that Dick Snow, Sam’s dear friend, was not able to attend due to his increasingly fragde health. Dick diedinDecember1997,followedin st 1998 by the deathof Ann Jungblut. Ann, of course, was Sam’s longtime collaborator and inseparable mpanion. Her death was a shock to us al, but most of all to Sam, and etty,hiswife.Buttherewasmoresadness to come. Sam fell dl in September and, despite a valiant struggle, died on October 6, 1998. In 13 short months we had gone from the “high” of the conference to the loss of three very special people.

But before ~scussingsome of this evidence, I would like ing about my eady association with Sam Messick,p ~ t i c u l ~ l y t year of our ~ollaborationthat began in 1955 shortly after th were National Institute of Health Postdoctoral Fellows at the Menninger Fo~dation. hy, one oftheleadingpersonalitytheoristsofthe our sponsor.

Wemust have been dedicated to t h ~ sresearch project, as each of us spent many hours at a mechanicalcalculator extracting b e n s i o n s by hand. In this chapter I discuss some of the many stuches that followed in the wake of that initial study.

I set out to provide evidence in support of three points: (a) one of the most f&tfid avenues for i d e n t i ~ n gand c o n ~ u constructs ~ g isthroughthesystematicstudyofhumanjudgmentas it applies to (b)the study of people’s constructs can be undertaken with the as one norrnally associates with psychophysical judgment; and (c) thestudyofpeople’sknowledgeofconstructsandof construct

A. quick calculation was required to estimate and predct their probable behavior. Should one exchangepleasantries,ifnecessarywithsignlanguage or grunts, ignore them, or run away? The fact that you and I are here, while other potential ancestors in countless past generations perished, gives us some confidence that our ancestors made the correct calculation.Andcapacity for such calculations might be conveyed in a cumulati~efashion in the t r a n s ~ s s i o n ofcultureand in the gene pool. The point that I makeis that social but central to the intekgence is not a trivial set ofcognitiveabilities, survival and success of individuals and of humankind. But we need not limit our consideration of the develop~entof social intekgenceto humanprehistory.Humansarehigherprirnates,andif there’s a singledescription that characterizes bgher primates, it is their social abdity. N. Humphrey (as reported by Shreeve, 1996), in reporting on his observations of mountain g o d a s remarked I cannot help being struckby the fact thatall of the animals in the forest, the guerrillas seemed to live the simplest existence. Gorillas live ir]. areas with a benign climate, abundant food, no natural animal enemies, and little to do but eat, sleep, and play. How have guerrillas and other great apes evolved the remarkable intelligence that has been observed?(p.292)

And the socialpressures on evolving human populationswereeven eater. This was particularly true after the advent of agricul~rewell over ten thousand years ago, when it became more necessary to form alliances with nonkin. The growthof consciousness about thepersonahties of others arose in part out of an outgrowthand adaptation to processingthe b e ~ d e ~complexity g of information from the social sphere, the te C O ~ U of~ more-or-less ~ ~ ” k e - n h d e d individuals. Social ce is honed in a variety of ways-by providing a social context for learning, by surrounding the individual with other clever individu~s who are s~ultaneouslylooking after the group but also, probably with greater motivation, themselves, by providing challenges involving c o ~ u ~ c a t i o n , threat, bluff,promise, and counter-threat. After theinvention of e and the opportunity for sedentary individuals to live in larger groups, sophisticated solutionswererequired for the problems of living and working together in lunited groups and for S lunited resources. According to Shreeve, in such a complex world, ordmary ence might not suffice: *
“he advantage would go to the player who was not only a keen observer of others’ behavior, but who could also peek inside their minds and anticipate theirnextmoves. No onehasyetevolvedanervoussystemcapable of directly reading the mindsof others.

My approach to understan~ngtheinferentialrelationshipsamong personality-motivated behavior stems from at least three sources. The first derives from the process of creating and evaluating a personality item.The second-and IhaveSarnMessick to thankfor this-is d r a m from e ~ e r i e n c ewithpowerfuljudgmentmethods in psychology, partic~arly &g. The third springs from two of the branches of with wkch I’ve had some experience, n ~ e l ~ , ~ ~ c a psychology, where clinical judgment is regarded as having a central place, dustrial psychology? where an understandtng of the decision- ma^^ ses of the employment interviewer has been an important focus of research-my own and that of others.
I haveprobablyreviewedandevaluated more than 15,000 personality, vocational interest, and attitude items in various assessment ventures. Even when I had reviewed only fraction a of that number, I r t it was possible to judge quite accurately how the item would its targeted scale, and what its relationship would be with irrelevant scales, as wellaswithsourcesofevaluativebias.Butgiven the Meehl (1945) manifesto on empirical strategies for personality scale c o n s ~ c t i o nand his ent for the method of contrasted groups, I was at first reluctant to for the role of human judgment.

8 Jackson prepared for given personality scale performedas expected (Jackson, 1971). m e n I tried to make the point privately with colleagues, that I can judge with considerable accuracy the degree of relevance of an item to a scale, they were often surprisingly vzilling to agree that I had superior insight into personality. However flattering this was, I doubted it and not only because many people granting me tius insight were my present and former graduate students, The question arose as to howonecould demonstrate the critical irnportance of “the constructs in people’s heads” in ~ormulatingthe rninihypotheses that comprise the creation of a personahty item? One of my first ventures in such a demonstration (Jackson,1971)was a sirnple m u l t i ~ e n s i o n a lscaling analysis of judgments of hypothetical people and of items. Consider the following person designed to represent the positive pole of the personality dimension of Autonomy. ~ ~ ~ ~ is ar free-lance ~ ~ writer. r ~ At~ oneeh erhe worked for a newspaper, but quit because he felt restricted by the company’s regulations. He now enjoys h i s work because he is h i s own boss. Edward spent the last year traveling alone through several European countries. He has currently taken up temporary residence in a large city’s Bohernian district. Edward strongly advocated the view that today’s young people are mere knitations of each other.Hefrequently tells otherpeoplethattheworldneedsmore “individuals.” His friendsdescribe him as independent, h e a d s t r ~ ~and ~, freedom-loving.
S d a r personality capsules were written for the negative pole of Autonomy and of two other Personahty Research Form scales, Imp~sivity and Dorninance. Alsoincludedwerepositivelyandnegativelykeyed persona~tyitems from each of the scales. Two sets of judges of hardy greater than averagesophlstication r e g a r ~ gpersonality rated the joint probab~tiesof occurrence of the behavior described by the people and by the items.Each set yielded three dimensionseachdefmedonly by the exemplars relevant to a particular scale. The average correlation between the correspon~ngprojections on the three dimensions between the two separate sets of judges was .99, indicating that when given the appropriate o p p o r ~ ~ t ordinary y, peoplecanmakeinformedjudgments about the relevance of the personality constructs reflected in persons and items. It might be argued that the above demon~trationwas based on items that had already undergone empirical scrutiny, which was true. Accordingly, I directed my attention to the entire initial pool of items for the first set of
The Constructs in People’s Heads 9 seven scales constructed for the PRF, which comprised before screening, from 100 to 140 items per scale. I evaluated the frequency with which each item was rniskeyed, that is, should have been included in the selected items ofanalternativescalebased on that item’s pattern of correlations with targeted and irrelevant scales.In no case did the number of rniskeyed items exceed a percentage of one tenth of 1Yo. Again, this illustration of human judgment in the item creation process supports the idea that the “constructs in people’sheads”show a correspondence withhow other people respondconsistently to construct-oriented personality items and scales. Resultssuchasthesegaveme the confidence to issue a challenge (Jackson, 1971). I suggested that the fruits of a couple of hours of work in preparing items by ordinary people be pitted against the most elaborate empirical item analyses using external criteria available, to determine which method yielded higher validties. Ashton and Goldberg (1973) accepted the challenge. They reported that journeyman item writers produced validties more than comparable with those obtained from California Psycholo Inventory (CPI) scales,whichareconsideredbymany to be the finest example of the empirical method of personality scale construction. In a replication of Ashton and Goldberg, I (Jackson, 1975) found that when given a clear scale defnition of the construct underlpg a scale, ~dividual undergraduate students produced scales y i e l h g three times the validity of CBI scales of Comparable length. Human judgment regardmg constructs of personality indeed warrant greater respect than accorded it by the radcal empiricists amongpast generations of psychologists.
’ I h s is a contentious issue in personalityresearch.Historicallymany
researchers found little evidence supporting accuracy in person perception. I and my collaboratorshaveapproached this issuewith a construct approach, one that requires that the information provided judges, and the behavioral outcomes that they are predicting, have some clear, demonstra~lerelationship with a personality construct, and in addtion, that traits and behaviors be linked in both inferential and empirical networks. We have often found it convenient and illu~natingto study the accuracy of inferential judgments of personalityby employing personality items (i.e., the statements of that comprise personality scales). The advantage of using

A number of p r o ~ e n authors, t including Bandura (1969), Mischel (l968), Schneider (1973), and Shweder (1975) argued that inferential trait relationships were based on semantic sirmlarity, and, accordingly, were ‘‘~Uusory” with littleor no validity.

These covered a range of values; in the case of the Jack Cole target the values ranged from slightly negative to 39, with a median value

In general, personality congruence had a considerably stronger effect than did the desirabitity of the statements made by job candidates. But there was a notable exception. Siess and Jackson had found that the job of gudance counselor was defined by desirability responding, as well as by personality traits such as Dominance, Exhbition, and Nurtmance. For the counselor job an interaction emerged, indica~ngthat if the self-pre skills wereseen as deficient byjudges, hgh personalitycongruencewas insuf~cient to elicit high suitability and job performance ratings. The &port of these fmdings concerning personality in the employment interview is that ordmary people are sensitiveto the nuances of personality re~uireme~ts of dfferent jobs, possessing “ c o n s ~ c t sin their heads’’ that not only p e r d t inferences about therelationshipsbetweenpersonality characteristics, but, accurate owle edge ofthenetworkof relations~ps between personality and work behavior, as well, even differentiating jobs that require a high-order self-presentations skills, and affording such skills eater weight when appropriate.
I have attempted to show in brief outlines of a few fflustrative studieshow SamMessick‘s introducingme to powerfuljudgmental methods and affording me the o p p o r to ~ work ~ ~ with him on construct validation problemshad r ~ f i c a t i o n sthat neither one of us fidy realizedat the outset. By thinking in terms of personality constructs rather than isolated facts or simple empirical fndings, one can hope for progress. My message is thus consistent with T, H. Huxley’s famous dictum that those who do not go beyo~dfactrarelygetasfarasfact. The useof a construct roach, even in some quite applied areas of psychology, like personality assessment,personperception,clinicaljudgment,andtheemployment interview, dcontribute to an understanding of certain of the processes perhaps, contribute to the betterment underlymg these endeavors, and d, of the human condition.

ersonality questionn~es as a means tocommu~cate about personality. From S perspective, a number of recommendations are listed for state-of-the art personality assessment. Item formulations should avoid nals (speci~ca~y,counterfac~~s), adjectival phrasings resultinparadoxes),and c o n s p ~ a t i o nlanguage. ~ The uld not containrepetitiveitems,stylisticvariation,and ppant i n s ~ c t i o n sto the assessor. ~veragingover multiple is a condition for proper assessments. With respect to the and sc of results, the use of principalcomponent analysis, correction for acquiescence, anchored scores, and natural confidence intervals are r e c o ~ e n d e d . In discussing app~cations, I argue that the use of personahty questionn~esin insti~tionalsettingsisproblematic, but in attend in^ to individualsettings self-mana~ement is served bydesigns p e r s o n ~ t y ~ n ~ o n m fit. ent
Inmost researchandapplications,personalitycomes from answers to questions of whata person is &e. The basic script involves threeroles-an investigator, who asks the questions; an assessor, who gives the answers; and the principal character or target person, whom the questions are about. 19
20 Hofstee In the compactversionof the script,wherepeopleareasked to assess themselves, the latter two roles are played by one and the same person; in other words, the questions are asked in the second person singular ( “ m a t are you &e?’) rather than the third (“What is he or she like”), although the actual g r ~ a t i c a lphrasing may vary. In the hll-size version, the investigator would command a sufficient number of independent assessors per target to attainanelementarylevelofnormal-scientificprecision (Hofstee, 1994). Conversely, in a subcompact version, an individual would ask questions about hirnself or herself, therefore, in the fast person singular ( ‘ m a t arn I like” or even “Who amI”); this p ~ o s o p h i c a rather l than psychological script is not considered here. Two developments have extendeda beginning of scientificrespectab~ty to the questionnaire construction of personality. First, research in behavior genetics has established heritability coefficients in the order of .4 for traits assessed by questionnaire Poehlin, 1992). This figure is in the same order of magnitude asthe g e n e r ~ a b ~of t ya questionnaire score over h e , item samplings, and assessors (Hofstee, 1994). Thus the modest generalizabdity raisesanargument a fortiori: As oneincreases the gener~abilityof questionnaire scores, the heredltycoefficientswouldapproachunity. C o n f ~ a t i o nof this argument is found in a study by Riemann, Angleitner, and Strelau (1997) using two assessors per target. “he heredity coefficients rose to the upper .bo’s, which is what would have been expected under the h ~ o t h e s i of s perfect heritabdity ofthe true score. Second, questionnaire investigators are taking steps toward getting their conceptual book-keepingin order. I feelless andless inched (seealso Hofstee, 1997; Hofstee, Ten Berge, & Hen&&s,1998) to takesides in ents on numbers like the big 5, the giant 3, or other numerological I do fmd progress in the exploitation of the lexical entities. But h~othesis-which holds that novel trait concepts can generally be represented in o r h a r y language-and, especially, of the well-tried EckartYoung Theorem, which provides us with a sequence of principal components of personalitythat follow the law of ~ n i s returns. ~ g Still, questionnaire research has a reputation of being quick and dirty. There is the story of the young psychologist who followed his wife to a distant post and mailed a question to hrs Rabbi ‘ m a t can I do by way of research in the middle of nowhere”; he received an immediate reply: ““Good question? my son; allyouneed is to keep a s h g them”. More seriously however, there is nothing unscientific about a s h g questions to others.
The ~uestionnaire Construction of Personality 21 Investigators maymostly prefer to find out by themselves, through e x p e ~ e n t a t i o nand objective measurement. At some point, one may thus beable to predict individual dfferences in extraversion,agreeableness, conscientiousness, emotional stabhty, and the &e by genetic diagnosis. But in the m e a n t i m e ~ w ~ cmay h last longer than some would expect-there is a c o n ~ b u t i o nto bemade to accurateassessment;even the progress of netic research of persona^^ depends on it. However, complacen~ about the questionnaire construction of personality is notin order. I sumarize somerecommended further hprovements in the interest of an optimal performance of the questionnaire script. Certain of these are quite technical, but the general point ofview is discourse-analytic: I present questionnaires as a way of c o ~ u n i c a with ~ g people, about people. Finally, I discuss questionnaire applications in various contexts.
ss stering questionnaireshad better not beviewedasaformof objective measure~ent;rather, it is a way of c o m m u n i c a ~ gwith the assessor (not with the targetperson). The ~vestigator depends on the assessor for hs or her information-for better or for worse, if one wishes. Once this s h p l e point is accepted, it serves as a powerfkl organizer of do’s anddon’ts in questionnaire construction and administration. Generally speahg, the investigator’s questions had better make sense to the assessor. Note that this recommendation is specific, obvious though it maybe: If one measuresasubject’sbrainmassasan indcator ofhis or her inte~gence,the measurement does not depend on whether it makes sense to the person. Preoccupation with measurement (as dstinct from assessment)maywellbe the reasonwhyelementaryrulesofsensible communication are frequently violated. Illus~ations ofitemformulation that wdl hinder the process of c o ~ u n i c a t i o nbetween the investigator and the assessor are the following:
The technical problem with negatively formulated items k e ‘‘Is not easily frustrated” is that a denial may logically have two quite different meanings, namely, the absence of a trait or its opposite. The communicative problem
2 Hofstee is that the question
maydrivepeoplemad. In the event that the target rson happens to be quite Stable and Agreeable, the assessor may be able muster sufficient intellectual sophisticationto read “not ea3ily frustrated” as a litotes (Oxford expressingofan aff~mativeby thene c o n t r ~ )The . answer would go &e ‘‘Yes, you might say that he/she is m]not easily frustrated, if youinsist on usinganunderstatement.” If, however,thepersonhappenstobeEasilyFrustrated, the expected response from the assessor is c‘No,it is not at all so that h s person is not easily frustrated,,’ thus,a reversal of a litotes, or a quadratic understatement. In out” experience, even thorough-bred intellectu~smay fmd this too much not be posed in a of a good thing, and wonder why the question could normal way. Note that even aff~mativeitems carry the problem to some extent. If the item is phrased as “Is easily fmstrated,” and the target person is quite StableandAgreeable,theassessoris still supposed to respond withan understatement. The problem may be met by defining the other pole of the trait in an a f f ~ m a ~ vmanner, e for example,“Keeps hls/her cool”; the assessor would be asked which of the two expressions would apply more. In many cases, however, the expressions would both have partly a specific m e a ~ g ,so that theassessorwouldhavechfficultyseeingthem as opposites. S
~xample:“Helpsdoingthedishes”;ingeneral:“traitconchtional upon situation.”Conditionals may followfromaninteractionisticpara wheretraits &e helpfulnessareindeedsupposed to betied to specific situations. (One may wonder, of course, whereinteractio~smends: Should we c h s ~ ~ as separate h helpfulness with respect to dish-washing in the ~ ~ ~ on using a detergent m o r ~ versus g evening, toward males v e r females, or not?).More often, however,conditionalsseem to comefroman investigator’slackof trust inthe ablltty oftheassessor to perform an egation operation ((‘does the target show helping behavior in general, more orless than others?”).The idea is to use the respondent as a vicarious observer rather n assessor; Buss and Cr&s (1983) act frequency t idea in the purest fom. However, people assess e, and hardly ever observe in a detached scientific r might as well try to capitalize on that expertise.
The ~ u e s t i o n n Construction ~e of Personality 23
A special problem with condttionals is that they may be counterfactual9 as can be ~ustratedby the above example: If the household c o n t ~ as dishwasher, the item would read &e ‘Would he/she help doing the dishes, if not for the fact that there is a dishwasher?”“.The case arises whena work attitude scale is tested (counterfactua~y) on a student sample. The most notorious example is the opinion pollster’s question: “If elections were held today, for whomwouldyou vote?” (for a dtscussion,see Hofstee Schaapman, 1990). Assessors may find it Eun to engage in speculation, but that is hardly whatthe investigator intended them to do.
Many questionnaire items revolve around a trait-descriptive adjective. This is not the way t a h g about people happens in everydaylife. De ( 1 9 ~ found ~ ) that personalities are dtscussed in terms of behaviors denoted by verbs; trait adjectivesareseldomused. In word counts of orhary language their frequencies are among the lowest. Trait adjectives may be found in ceremonial and official discourse like eulogies,letters of reference and, most notably,psychological reports. In such commu~cations,they may serve the purpose of diplomatic vagueness. However, that is hardly what an investigator wants from assessors. In past yeam, we have spent much time and effort in developing a large pool of brief concrete sentences for p e r s o ~ ~ tassessment. y Wereas theyappear to fit in the same m u l t i ~ e n s i o n a lspace as traitadjectives, both their c o ~ u n a l i t i e sand their self-peer validties run higherthan those ofadjectives ( H e n ~ ~ s , 1997). A special problem with many adjectives arises when they are used in self-report (Hofstee, 1990). One may describe a t h d person as Modest or Superficial, but seif-description in such terns is paradoxical. Any claim that I would be a Modest person would only testify to myimmodesty;if I declwe myself to be a superficial character, my audience must presuppose a measure of profoundness on my part without which I would be incapable of finding myself Superficial-and that would be precisely the intention of my disclaimer. Thus to adnimster such items for self-report is to place the assessor in a classical double bind. Some might react &e the b~dge-player who cannot bemisledbecausehe or she lacksfantasy.However9they would hardlyrate as ideal assessors.

To assess is to be in office; assessors of personality are not asked about es or dislikes,any more thanpeerreviewersaresupposed to esercise their predilections.

A frequent complaint voiced by respondents to p e r s o n ~ t yquestionnaires is that their consistency is being checked. In a sense, that apprehension is correct: To attain reliability and construct validity, the investigator has to that psychome~c represent a constructinseveralguises.However, rinciple is no excuse for repetitiveness. First, hlgh redundancy indicates a “bloated-speci~c”(Cattell, 1964) construct; any trait that is worth assessin is broad enough to have many &verse manifestations. Second and mos rtant in the present contest, redundancy is a form of rudeness. In ary Life, one would get slapped in the face when posing essentially the same question twice, let alone 10or 20 times. An elegant technical solution for the d d e m a is available that is rarely ed. It consistsof p~cipal-componentscoring, so that everyitem btains a nonzero weight for every construct scale.We (Hofstee et al., ~ 9 have ~ shown ) that prin~pal-component scoring is the logical consequence of selecting itemson the basis of their item-scale correlation. ore genexally, I cannot think of any excuse to use unit weights in any scoring key). With this flexible and efficient procedure, items can be used at are blends ofunderlpg constructs; for esample, Cordtality is between s ~ a v ~ r s i oand n Agreeableness, ~ e t e ~ a t i blends o n Emotional Stability Conscientiousness.

~ o n the g most misleadingexpressionsinthepsychologicaljargon is personality test (foraquestionnaire),carrying a S stionofobjectiveness that is largely unwarranted. Administering a se1 number of persons, for example, is quite different fr scoring intelhgence test. Each person gets the same intelligence test and key, but each responder to a questionnaireis scored by a dfferent assessor, namely, that person himself or herself. Even if one would opt for a test s ~ ~ l i design n g and administer a different intelligence test to each person, the comparability among persons would still be hgher: total scores on IQ batteries may beexpected to correlateabove -8, whereas the c e h g for dfferent assessors is about .6. So the usual questionnaire a ~ s t r a t i o nis a h to having each applicant select a different IQ-test to his or her k g , whosegeneralizabilitieswouldbefarbelowstandard.Needless to say, internal consistency coefficients of questionnaire scales, which may be quite high,have nothing to do with this argument (to the extent that a questionnaire’salpha is lessthanunity, it onlydetracts further from its genera~ab~ty). A minimal condition to bring personahty assessment up to elementary egation: averaging over a number of independent judges. will not thereby be objective, but a sufficient degree of intersubjectivity can be attained. The argument is not specifically dlrected against self-assessment: The person hmself or herself, as an assessor, has certainstrengthsandweaknesses(Hofstee,1994),and it is anempirical question whether self-assessments are moreor less representative and valid thanother-assessments. The cardinal point isthatself-reportshave the ~ n s ~ o u n t a bhandcap le of being single by defnition. So at the very least, e to be supplementedby other-assessments. primarily technical;its forma~ation tionargumentis follows the lawof large numbers and the function derived independen~yby Spearman (1910) and Brown (1910). However, it has profound discursive ~plications.The assessor is approached as an exchangeable element of a
The Questionnaire Construction of Personality 27 set of experts. That position of exchangeability shows resemblanceto being a subject of research. So on the one hand, assessors are coworkers of the tor, who depends on them for theirprivilegedinformation; however on the other, they are not approached for their personal point of view; they should realize that any unique variance in their assessments is part of the error term. (The same holds for other forms of assessment and evaluation, most notably,peerreview). In our Five-FactorPersonality Inventory (FWI; Hendrks, 1997) we &ve home the point by m a i n t ~ g athird-personformulationeveninthecaseofself-report. Another ~plementationis to instruct assessors to predtct the average assessment, and to reward them to the extent that they succeed (Hofstee, 1995).
SU C o ~ u n i c a t i o nof questionnaire results is an integral part of personality assessment.Recently,we(Hofsteeetal.,1998;Hofstee, Ten Berge, & Snijders, 1997) have applied ourselves at aspects of it. This section contains a restatement of some results.
A h o s t all personality constructs, when scored in socially desirable chection, have a negatively skewed raw-score dtstribution; mean scores are above the neutral midpoint (..g, 3 on a scale from 1 to 5) of the scale. C u s t o ~ procedures ~ ofrelativescalingthereforeinvolvemoving the midpoint. That would be inconsequential with unipolar scales where any midpoint would not have a naturalmeaning.With the bipolar scales of personality, however, the midpoint is where a trait shifts into reverse gear. Moving the midpoint is thus a manoeuvre that can pretty well ruin the constmct. Less metaphorically: A person whose Conscientiousness or Emotional Stability would be assessed as somewhat above the scale midpoint, would obtain a somewhat negative score on the relative scale. That is not what the assessor had in &d. Other cases suffer from the rough treatment as well, though less dramatically: A somewhat Sloppy person, for example, would be reported to be clearly Sloppy. A radicalsolution to this problem is to resort to absolutescores. Hofstee and others (1998) present the appropriate procedures for the use

However with bidirectional scales, acquiescence is the tende to endorse bothpositive andnegativeitems,whereassocial desirab~ty wouldinvolve endorsing positive items and rejecting undesir~bleitems. Another sunders st an^^ is that acquiescenceis a axinor artifact (e. ~unnally,1967, p. 611-612).We found acquiescence variance to comparable in size to the third p ~ c i p acomponent l in hetero~eneoussets of questionn~e items (Hofstee et al., 199~).

con~denceor credibility intervals would be a step others(1997)havedeveloped natural confidence require an arbitrary decision with respect to the p covered ( ~ 0 ~90%, 0 , and so on). In our pro s ~ b u t i o nof a target person’s true score is pine
30 Hofstee background hstribution, for esample, the prior distribution of true scores in a relevant population or subpopulation. The natural confidence interval is located between the intersection points of the target and background distributions. Thus, the reporting of a score interval is constructed as a bet between the investigator and an opponent who would, in the example, fmd the individual assessment uninformative: The natural internal is where the ~vestigator’s probabhty is hlgher, therefore, it is the interval on which the investigator places his or her stakes. A spectacular property of this natural confidence interval is that its midpoint is the target’s observed score rather than the true score as in classical test theory.
With respect to questionnaireapplication, a sharp distinction should be madebetweenindividualand institutional decision contests. Generally speakmg, assessments of personality have their place in individual rather than institutional contests.
ontexts Institutional application contests like personnel selectionand student admission are basically contests of maxirnum performance, whereas personality summar~estypical behavior. Thus the pragmatics of selection and admission situations constitute a formidable obstacle against personality description. Consequently, answers to the question of what a person is like can only be ambiguousin that setting. According to a widespread but prinitive notion, the answer to an item like “Do you tend to keepyour appointments” wouldcome about as follows: The self-assessor makes up Ius or her mind on the basis of past behavior, and subsequently engages in self-enhancement in socially desirabledirection; thus the answerconfoundsindividualdifferences in punctualityandfakmg good. This notion hasgivenlead to attempts to control for social desirability. The failure of that approach was documented in the early1960’sbyDicken(1963)and, most recently,by Ones, ~ i s w e s v ~ aand n , Reiss (1996). In a more subtle conception, the answers are programmatic. After all, from the point of view of the applicant, the institution cannot legitimately be interested in his or her past behavior; the task is to preview applicants’

Tragically, the’less self-insight the applicant has, and the more lhrs or her ideas are influenced by voluntaristic theories on the changeab~tyof personality, the easier promises are submitted. But there need not be anyquestion of l p g or faking.

A realistic instruction would be the following: “For each item, it wrll be quite evident what the most socially desirableresponse option is. The more socially desirable your answers, the higher are your chances. Also, there is no way of checking them. Only, in the longer run youmayhavedone yourself and others a dmervice if you misrepresent yourself. Also, don’t fool yourself into thinking that you could actually change your personality to becomeentirelysociallydesirable.” “hat wouldalso not helpmuch: Cynical and short-sighted applicantswould still be at anadvantage. However, the instruction wouldcomplywith requirements of informed consent, andwouldbebeneficial to the publicrelationsofapplied

Still, most of the research on person environment has dealt with these more epherneral phenomena (for an overview, see of, 1996).

The 1961 volume of the Annual Review of Psychology was the first to have a chapter devoted entirely to recent research on personality S interesting to note that the psychologist c o ~ s s i o n e dto write this review wasSamuelMessick(1961) whom we are honoring at this sym I wrotethethirdreview on personality s t ~ c ~ r e Four yearslater, ~ o l t z m a n ,1965),ataskmademuch shpler byMessick's outs scholarship and definitive work. My acquaintance with Messick go to his arrival with Dou Jackson in 1956 on the campus Men&gerFoundationineka,Kansas,where both of them were postdoctoral research fellows under Gardner Murphy in the field of personality &g of a close friends^ and assessment. "his meetingwas the b ed to thisday. I wasprivil professionalcollaboration that has CO a consultant who periodcdy visit that h e to beresearch exciting research program had been Foundation where a vigorous, developed under ~ u ~ h yleadership. 's It was a distinct honor and pleasure to be called backto ETS on the happy occasion oft h s conference. At an APA s y m p o s i ~ in 1963 c o ~ e m o r a t i n gthe 25th a n ~ v e r s of a~ the classical pub~cation,Explorations in Personality, by Henry Murray and his associates, I presented six major unresolved issues related to rec dilemmas in p e r s o n ~ t y assessment as follows: (1) the m e a ~ g personalityassessment, (2) how many things mustbe known about an ~ d v i d u ato l understand his personality, (3) how personali separated from method variance, (4) whether we areb bound theoryandtechniqueofassessment, (5) whether wecanever develop a systemic, comprehensive personality theory closely linked with empirical data, and (6) the moral dilemmas created by personality assessment(Holtzman,1964).Today most oftheseissuescontinue to
38 Holtzman persist although in somewhat different form,one has faded from the scene, and new ones have taken its place.
The meaningofpersonalityassessmentcontinues to bean important, unresolvedissue,dependmg on one's point ofview. Personologists and many c h c a l psychologsts continue to insist that one must h o w a great deal about an individualto truly understand his personality. Specific scaleor factorscoresareviewed as eitherirrelevant or too superficial to prove useful without a thorough analysis of an individual's motivations, aspirations? hstory, andlifecircumstances.Althoughsomepersonality m e a s ~ e smayhave a lhmiteduse to confirm personal impressions or to as provide supplementary information, they are generally dismissed incidental to a deep understandmg of personality. ~sychome~cally oriented personality psychologsts differ strongly with this idio~aphicpoint of view, insisting that a true science of personality must focus on meas~ementif any progress is to be made. The primary focus of scientific study should be the development of more reliable, valid measures of hportant aspects of personality that can then provide a stable framework within whichto gain a deeper u n d e r s t a n ~ gof the indmidual. anypersonality psychologsts believe a stableframeworkis now at p chometric t h i n h g on a herarchical hand withtheconvergenceof systemdominated by thegeneralFivefactors.Butsuch enthusi~s~c optirnism is probably premature. There are good reasons why the idio~aphic-versus-nomotheticdebate that ragedvigorously in the 1960s has apparently faded away. Psychology has become more f r a ~ e n t e dand c o m p a r ~ e n t ~ ewith d the growth in numbers, the diversity of research, and the proliferation of specialized societies and scholarly journals. Consequently, the many thousands of psychologists in applied settings who e n ~ g edaily inpersonalityappraisals for practicalreasonshavelittle discoursewith the academic, p s y c h o m e ~ i c ~oriented y psycholo~sts engaged in personality research. Eachgroup has a different mission and set of priorities that rarely meet. X'he fact that the issue has faded from the radar screen only means that the two groups have little more to say to each other at present.
Personality Theory and Assessment 39
e different worldsof clmica1 assessmentand p s y c h o m e ~ c ~based y personality assessment are once again beginning to collide and even show boration, The most notable example is the long I in c h c a l assessment aswellas in perso oses of the two worldsare quite differentversus assessing normal personality and terion-based methods versus rational constructaboration has been uneasy, difficult, andoften doomed to failure. Several trends since the 1980s point to a more optimistic e for resolution of these issues. rapid rise of computer-based clinical assessment methods in sishasforcedcluzicians to tlxnk ~ f f e r e n ~about y their the same h e , thesenewcomputermethodshavegreatly increased the efficiency and power of those chicians who have learned to use them wisely. Second, a growing number of younger, highly competent c~cian-researchers and personality psychologists have a shared d in both camps, c h ~ e n each ~ g other to develophybrid S andsystemsofassessment.And third, academicleaders in points of view, encoura~nggraduate e theirideasand to undertake new erhaps the most porta ant new trend accelerating a changeof is the externalmarketplace that is d e m a n ~ g ~ o n chicians g more a c c o u n t a b ~and ~ value for the moneyfrom the thousands of practitioners whose ~ v e ~ o depends od on it. The old ways, of s p r i n b g a lot of projective-technique jargoninto a standard case history ands u ~ n g that justifies the proposed treatment or satisfies the st, are no longeracceptable to manymanaged-care payers.And in manysituations, the chical or counseling p~ychologist~s u ~ q u ~ valued ly c o n ~ b u t i o nto the improvementof a clientisbeing c h ~ e n g e din that same m ~ k e ~ l a by c e social workers and other therapists whose services are available for a lower price. Therefore it is incumbent on g the way in chical assessment to develop stronger, efficient, more valid methods that capitahe onthe psychologist's special training and role as a mental health senrice provider.
od exampleofthese e m e r p g newdevelopmentsis the special c area known as personalitydtsorders.As chicians increasin the widelyaccepteddiagnostic standards that areperiodically refined under leadership ofthe Arnerican Psychiatric Association, known as the Diagnostic andStatisticalManualofMental Disorders or DSM IV (APA,l994), there is a compellingnew opportunity for co~aboration between clmicians and personality psychologsts, One serious s h o r t c o ~ ~ of the revised DSM IV has become apparent in the lack of widely accepted ostic categories and efficient techniques for the assessment of personality disorders. Reahation of this problem has already stimulated a flurry of new research and developmentthat dundoubtedly be expanded. U n b e any other areaof psychodia~osis,personality disorders arean obvious target for f h t M collabora~onbetween chicians and personality psycholo~sts.
One old issue that heats up occasionally concerns the relative value of the empirical method of developing scalesby selecting items that correlate with anexternalcriterionofspecial interest as contrasted with the rational method of starting out with a theoretical construct and then developing items that are chosen or dtscarded accordulg to the degree of homogeneity produced in the fiial scale. One side of h s controversy argues that if you have a known criterion to be predicted, such as the accurate di id schizophrenia, the best approach is a strictly empiric isanexcellentexampleof a successfullydevelopedpersonality ased on criterion-referenced items. The other side insists just as t a scienceofpersonalttyhas to be b d t upon theoretical constructs where construct validltyis the stern tashaster that should dtctate the methodof scale construction. Then once the scalesare appropriately constructed, a sound theoretical framework can be developed for mapping the relationships between the known personality factors and er independen~yr e c o p e d characteristics or specificbehavior of interest. Unlikeunresolvedissuesbetweencliniciansandacademicpersonaltty psychologsts, the empirically oriented advocatesand the rational scale supporters share certain beliefs in cormnon that make it far easier for them
Personality Theory and Assessment to interact productively. First o f all,theyare dedicated to h p r personality m e a s ~ e m e n tthrough research based on sound psycho ethods. Second, they generally begin with objectiv stically based items in questionnaires, peer ra ations of actual behavior. And third, they both c h-based academic s e t ~ g swhere s ~ a r - ~ n d e d oductivity.

42 Holtzman differing points of view of Gutlford, Cattell, Vernon, and Eysenck. Today the focus of many personahty psychologists on the so-called Big Five of Extraversion, EmotionalStabiltty,Conscientiousness, Nurturance, and Inquiring Intellect can be contrasted with such specific scales as Spielberger’s(1983)State-TraitAnxiety Inventory, the BeckDepression Inventory (Beck,Steer, & Garbin, 1988), or the Bussand Perry (1992) scales for measuring four aspects of aggression. Nearly everyone now agees that both general and specific traits have a rightful place in any comprehensive personality system. But what that place should be is still a c o n t i n ~ issue. g A hierarchical system withthree or four levels varying from highly specific to general traits is widely accepted even indmidual preferences may focus on only one or two components or levels.Whetherapersonalttysystemand its components should be conceptualizedentirelyon the basis ofasomewhatarbitrary, although widely accepted, method of factor analysis, however, remains to be seen. As Loevinger (1994, p. 6) has pointed out, “There is no reason to believe that the bedrock of personality is a set of orthogonal...factors, unless you in rowsand think that nature is constrained to present usaworld columns.”
US I The direct methods of asking someone questions dealing specifically with traits or asking others to ratean in~vidualonsuchtraitsare the most popular approaches to personality assessment for obvious reasons. They haveanappealmgfacevalidity,theyareusuallysimple, straightfo~ard methods,theyarebased on commonlyunderstoodlanguageused to describe personahty, and they are economicalto employ, especially for large numbers of individuals. But they also suffer from ease of f a h response sets, variance due to the situation, and other extraneous factors that lower their validity in all too many situations. Considerable attention hasbeengiven to embedding dtspsed vahcttyscales in the more sop~sticatedpersonalityinventoriessuch as the l”P1, but they stdl frequentlyfall short. Andevenmore important, anycomprehensive approach to personality must delveinto enduring personal dispositions and stylistic behavior that reflect levels of organization and f u n c t i o ~ gbeneath the surface of verbal expressionor interpersonal behavior.
Personality "heory and Assessment 43 Indirect methods, by contrast, involve assessments where the meaning of the measurements is dispsed so that the individual hasn't the slightest idea how his responses will be interpreted. Such methods often involve asking an individual to perform a specific, standardized task such as using hs i m a ~ a t i o nin viewing meaningless colored inkblotsand reporting what he sees. The ThematicApperception Test, theRorschach or its more ~sychome~cally basedoffspring,theHoltzman Inkblot Technique,are favored by many clinicians as projective techniques for personality assessment because it is very difficult to fake one's responses or malinger when reacting to such ambiguous stirnull. "he most comprehensive studies of indirect approaches to personality assessment are still those of Raymond Cattell and hs associates that were done overforty yearsago.Cattell(1963)stated that overa thousand different behavioral measures were developed and studied in a number of factor-analytx, multivariate matrices during the 1940s and 1950s. Many of these measures were performance scores on ingenious tasks that survived as partof his revisedObjective-AnalyticPersonalityFactorBatteries 21 primarypersonalitydimensions designed to measurewhathecalled (Hundleby, Paw&, 8r Cattell, 1964). A basic difficulty with most of them, however, was the very low order of intercorrelation between these inhect, objective test scores and either behavior ratings or personality questionnaire scores. The possibility of indirect, performance tests of personality were so appealing in the 1950s, largely because of Cattell's work and the studies of field dependency by Witkin, that a national conference was held in 1959 that I chaired under sponsorship of the NationalInstitute of Mental Health to review this rapidly growing, new field to summarize the work to date, and to point the way to future promising areas of research.A wide range of interesting performance tests, many of them derived from experimental studies of perception, learning, or cognition, were discussed. Many proved to be highly reliable measures of individual differencesthat were interesting in their o m right but faded to correlateappreciablywithany other measures of personality. As a result of these disappointing results, the focus upon perfomance tests of personality faded away and greater efforts were devoted to a better ~ d e r s t a n d i nof~ how the objective measurement of personality could be improved by a deeper under st an^^ of how personality variance could be separated from methodvariance.

One frequently hears the criticismthat personality theories and assessment, especiallytrait-basedinventories,arecultural-boundbecauseof derivationfrom the languagesofWestern Europe. Expansion of c cultural studies of personality ~ o u g h o u the t world in the late 20" cen
46 Holtzman has produced convincing evidence that the main dimensions of p e r s o n ~ t y found in America and Europe are more universal than earlier critics have believed. Recent reviews by Butcher and Rouse (1996) of clhcal assessment and by McCrae and Costa (1997) of personality trait structure reveal a large number of major stuhes in just the past several years that demonstrate the wide applicab~tyof personality assessment across many different cultures and languages. "he issue that now seems to be emergmg is not whether personality assessment is culture-bound, but rather, how are the basic ensi ions of personalityexpressed in hfferent culturesand do culturalvaluesand customsinfluence this expression.Mostlikely there will be c o n ~ ~ n g expansion of cross-cultural research on these important questions in the near future, spurred on by the growing agreement concerning the nature of ~ersonality-tr~tstructure and facilitated by high-speed, inexpensive, inte~ational comunication.
Thirty-five years ago there was considerable concern about public i n d i ~ a t i o nover possible misuses of persondty assessment.Although public mistrust stiU exists in some quarters, psychologists and others have properly addressed the legitimateethicalandsocialissues.Adequate safeguards for the protection of human subjects have been built into the entire process from reviewing researchgrant applications to monitoring the collectionandanalysisofdatawhile protecting the confidentialityof participants. Many of us fmd these restrictions and procedures f ~ s t r a ~ g and t i m e - c o n s ~ gNevertheless, . such safeguards are necessary, At least the educated public in hlghly developed countries is much better informed than in the past. And yet, the fears that psychologsts have powerful, secret techniques for uncoveringprivate information about anindividual or c o n t r o ~ ghis personality stlll lurk in the bac to the conduct of scientific research. Moral & e m a s created by personality assessment in other, more a~tocratic,less openly democratic countries are more kely to become a serious problem that will bear watchmg carefully in the corning years. The protection ofhumansubjects, the educationof the generalpublic,and
Personality Theory and Assessment 47 establishment of high standards o f ethical conduct are porta ant regardless of where the personality assessment is done. " h e last fifty years o f the 20th century have seen a great deal o f progress in the development of personality theory and measurement. In spite of these important scientific advances, current issues in the field have a remarkable similarity to the issues and controversies debated many years ago. O f course they areusually expressed in a chfferent form today. ether these same issues d still be o f majorconcern 10 or 20 years from now is difficult to say. But one b g is virtually certain. The complex and changulg nature o f personality d continue to be a major challenge to f inchvidual and those who seek a tmly comprehensive u n d e r s t a n ~ g othe social interaction. " h e field has more promising leads for young investigators to pursue than ever before, assuring that rein~gorated ladvance more sigmficantly than in personality and c h c a l measurement d the past.

The topic of this essay is restricted to one response bias--sa&& ~ e ~ ~ ~ a ~ Z e ~ e ~ o n (SDR)"defined ~~ng here as the tendency to give overly positive selfdescriptions. Note that my q u ~ f i c a t i o n ~ ~ seldom e ~ ~ included is in d e ~ t i o n of s SDR, but is of central importance inthis essay. Indeed, I w li argue that no SDR measure should be used without sufficient evidencethat high scores indicate a departure from reality. This essay begins witha selective review of the wide variety of constructs is particuldy held to underlie SDR scores. Coverage of the early developments selective because that history has already been reviewed elsewhere (Messick, 1991; Paulhus, 1986). The latter part of the essayemphasizestherecent developments with which I have been associated. Although my approach departs from theirsin some respects,my understanding of the topic of SDR draws liberally from the substantial empirical and theoretical contributions of the team of Sam Messick andDoug Jackson (e.g., Jackson &:Messick, 1962; Jackson, 1961). And specificto this volurne, my depiction of the interplay between response styles and personality can be traced to Messick's insight^ analyses @am& &:Messick, 1965; Messick, 1991).

Assessment psychologists have agreed, for the most part, that 'the tendency to e sociallydesirableresponses is ameaningfulconstruct.

The validity of such SDR measures has been supported by demonstrations of consistency across diverse judges in the desirabhty ratings of those items 8c Messick, 17621). Moreover, scores on SDR scales ~ d w a r d s1770;Jackson , developed from two hfferent item domains (e.g., clinical problems, personality) were shownto be hi~hlyintercorrelated Pdwards, 1970). In short, the same set of respondents was claiming to possess a variety of desirable traits. psychome~callyrigorous E ~ e m p ofl ~the minimalist approach was the but theoretically austere creation of the SD scale by Allen Edwards (1957, in r e p r e s e n ~ g SI) 1770). ~ o u g h o uhis t career, Edwards remained cautious scores as individual differences in rates ofSD responding” (Eidwards, 1790, p. 2 ~ 7‘2)At the same h e , the proninence of his work derived m d o u b t e &om ~~ the implication that(a) highSD scores indicate misrepresentation and that (b) ~ e r s o n ~measures ty correlating highly with h i s SD-scale werec o n t ~ a t e to d int of htili Walker, 1761).

The notion that SDR appears in two dlstinct forms was recognized by a number of early researchers (Cattell &, Scheier, l(161; Edwards, Diers, 3 See PaulhusandJohn (1998) for other reasonswhy the claims of high MC scores cannot be taken at face value.

It was not untll the review by Damarin and Messick (1965)4 that a detailed theoretical interpretation of the two factors was offered (see Factor 1was saidto involve the defensive dlstortion of one's private self-image to be consistent with a global evaluative bias.As a substantive label for &IS factor, they proposed autisticbias in s e ~ r ~ uAssociated r~. personalrty traits included self-esteem and ego-resdiency.

Perhaps the most clear-cut example of the rational approach to SDR scale development was the work by Sackeim andGur (1978; Gur &:Sackeim, 1979; Sackeim, 1983).

the subsequent chapterby Messick (1991).

To compose a set of items indicating self-deception, the authors drew on the p s y c h o - d y n ~ notion c thatsexual and aggressive thoughts are universally experienced yet often denied. If respondents overreact to questions with offensive content (e.g., “Have you ever thought aboutkilling some one^'), then theyareassumed to haveself-deceptivetendencies. To measureothereception, the authors wrote items describing desirable behaviors that are so public and blatant that they axe not subject to self-deception (e.g., ‘61always pick up my litter”) According to the authors’ reasoning, then, excessive clhs of such commendable behaviors must involve conscious dissimulation.

Insteadofconceding to theone-factorconception, my researchgroup embarked on a new phase of item-writing. An extensive range of items were rationally composed to tap every conceivable f o m of self-deception and impression management (Paulhus, Reid, & Murphy, 198’7).A swarm of factor analyses consistently revealed one factor of impression management and two factors of self-deception. The impression mana~ementitems that cohered were largelythe same items from earlier versions of the measure going to back Sackeim andGur (1978).

The sensitivity of the IM scale also far exceeded that of any of the NEO-FFI measures of the Big Five personality traits (Costa& McCrae, 1989).A similar pattern was observed ina study of job applicants vs.incwbents (Rosse et al., 1998) of In other studies, theSDE scale, but not the IM, predicted various lands self-deceptive distortions, for example, hdsight bias poorens, 1995; Paulhus, 1988). More than 40 other studies, most outside our of laboratory, have added to the construct validity.For a more extensive review, see Paulhus (1992%).

60 Pauhus The implication ofthis understated commentwas that researchers making allegations about response bias must do the work of demonstrating departures from realtty: This taskrequiresthecollectionof crehble measuresof personality to be partialed from self-reports. Dmarin and Messick (1965) went on to lay out the statistical p ~ t i o n i n gnecessary to isolate the residual bias component (p.21). This recommendation proved invaluable in my work with Oliver John on d e t e ~ n the g structure of self-favoring bias (Johnst Paulhus, ~ 0 0 0Padbus ; & John, 1998).We needed a unit ofbias to represent each part of the personality space.5 For each personaltty variable, we collected self-ratingsto compare with a more objective criterion, namely, ratings by knowledgeable peers (i.e., friends, family). In the ease of intelligence, we also IQ used scores as a criterion. Each self-rating was regressed on its corresponding criterion to create a residual score representing the departure of the self-rating &om reality. Factor analysis of a comprehensive set of such residuals should uncover the structure of self-favoring bias. Using the Big Five dwlensions of personaltty plus intelhgence to represent a smaller space than personality space,our factor analyses of residuals revealed the 5-space of either self- or peer-ratings. The first two major dimensions Extraversion and appeared as in Figure 4.3. Factor 1 wasmarkedbythe Openness residuals whereas Factor 2 was marked by the Agreeableness and Conscientiousnessresiduals.Apparently,thestructure of biasbearslittle resemblance to the standardBig Fivestructure, If anything, these factors look more like agency andc o ~ u n i o n (see Bakan, 1966; A replication study helped to clarify the meaning of the bias factors hough a widevarietyofself-reportmeasures.Theseincluded theadditionof traditionalmeasuresof SDR (Marlowe-Crownescale) as wellasrelated measures of self-enhancement (e.g., Narcissistic Personality Inventory). The onto additions allowed us to project a variety of bias arrd personality measures the two bias factors. The resulting projections (correlationswith the factors) are depicted in Figure4.4.
5 The last 15 years of work on the Five Factor Model suggests that it captures the 5 most important dimensions of personahty (TViggins, 1996). There is some dispute, however, about whch rotation is optimal. 6 The results were more clear when we separated Conscientiousness into Dutifulness and Ambition following Paunonen and Jackson (1996).It is the Dutifulness measure that is most faithfid, conceptually and empirically, to the Gamma factor.

Note festthe staking match of thetwo R D R subscales (SDE and SDD) to the two bias b e n s i o n s . Immediately, we have reason to believe that the factors represent Alpha andG a m a , the bias factors named by and explicatedby Damarin and Messick (1965).Note h t h e r that narcissism, as measured by the Narcissistic Personality Inventory (Rashn & Hall, 1981), marks Factor 1 along with SDE7. Factor 2 resembles earlier studies in being well-marked by the IM and SDD scales and less weu by Eysenck's Lie scale, the " P I Lie scale and the Marlowe-Crone scale. Rem~kably9 the venerable Alpha and Gamma SDR factors (noted above) have been re-generated via a novel technique requiring only personahty content measures. n e convergenceofresultsacross the twotechniquesadds substantial credibilltyto the Alpha and Gamma factors. In particular, the new technique provides evidence that both Alpha and Gamma assess departurefrom-reality. R a t is, high scores onboth SDR factors involve overly positive se~~-descrip~ons (Q.E.D.). One remaining puzzle isthe fact that two conceptually chfferentresponse style measures, Self-Deceptive Denial and Impression ~ n a g e m e n t , onf dthe same SDR factor, Gamma. How canthe response styles previ conscious and unconscious distortions (l'aulhus, 1986; Sack now coalesceat this point? In anonymous student samples, where pressure for self-presentation is rninirnal, SDD and IM appear to be capturing sknilar persona~tycontent. Yet IM is more responsive to i n s ~ c t i o m~pulations. n~ In short, G m a subsumes both consciousandunconsciousaspectsof common content. Apparently, I have to question my previous contention that level of consciousness is the core chfference between Alpha and G m a factors ofSDR (e.g., Paulhus, 1986). " h s theoretical revision makes it easier to explain whythe Gamma l o a h g of an allegedly conscious deception measure (IM) does not disappear entirelyin anonymous responses. With Gamma as a content factor9it is now quite understandable that IM should appear even when there is no audience to motivate irnpression management,
In a more recent set of experiments, we sought to clarify the Alpha and a m a factors via a series of studies varying self-presentation instructions Notareschi, 1993). First we wondered why Gamma measures were 7 A number of recent reports on narcissism and self-deceptive enhancement suggests substantd primary measures, NPI and SDE (McHoskey, Wortzel,& overlap inboth the constructs and the Szyarto, 1998; Paulhus, 1998a; Raskin, Novacek, & Hogan, 1991).
Socially Desirable Responding 63 so sensitive to instructional manipulations (e.g., Paulhus, 1984). m e n gven standard instructions to respond in a socially desirable fashon, respondents reported that they interpreted the instruction to mean that they should respond like a “niceperson” or “good citizen.” It struck us that this interpretation of social desirab~tywas rather nmow, focusing on content related to eableness and dutifulness, i.e., communal traits. Accordlngly we tried a agentic e f o m of instruction to respondents: ‘“Respond to ~uestionn~ ine a way to impress an experimenter with how strong competent you are.”h and behold,the SDE was more sensitive thanthe IM scale8 to these instructions (Paulhus, Tanchuk,&:Web, 1999). In retrospect, yet they have dramatic these fidlngs seem emba~assingly obvious; implications for previous research on SDR. First, it is now apparent why the items onW i g ~ s 7Sd s andother G a ~ a factor scales contahed those socially desirablebut distinctively conventional items.9Recall that thesemeasuresweredevelopedusing role-pla~ng instructions that emphasized co~union-relateddesirabhty. Second, it now seems obvious why Gamma-related scales were so responsive to instructions. They containthe very content that is implied bythe instructions. Third, Alpharelated measures may beno more unconscious (and therefore self-deceptive) than G m a measures. “hen what, after all, can we make of these two factors? anonymousconditions.Both respond to f a h g instru consciousandunconsciousaspects to them.Atleastwedon’thave to withdraw the (thankmy n o n c o ~ t t a l labels, ) Alpha and Gamma. “he “final” two-tier conception suggests that (a) Alpha and G a m a be ~ s ~ ~ sinhterms e dof personalitycontent, and th deceptive style and an impression m~agemen Gamma are held to be two constellations of origins in two ~ n d ~ e n tvalues, al agency andCO 1998).Excessive adherenceto these values results in self-deceptive tendencies, bias. whch we label,pistic bias and mo~a~istic AssociatedwithAlphaisan egoistic bias, aself-deceptivetendency to exaggerateone’ssocial andintellectualstatus.

Such deliberate~ z a t i o of n faults might also be seen in religious settings, or in employees who are tqmg to hold on to the status quo,or legal defendants tqmg to avoid p u n i s ~ e n t . To fully assess the two-tiered system of SDR constructs, four types of measures are needed. Fortunately, three out of the four have been avdable fox some h e . Self-deceptive enhancement can be measured with its namesake (SDE) or the Narcissistic Personality Inventory (see Paulhus, 1998a). Selfdeceptivedenialcanalsobemeasured by itsnamesakescale(SDD).

“I am very brave” and “1am exceptionally talented”. Such items tend tonot be c l b e d , even by narcissists, under anonymous condttions. But the endorsement rate is higher under agency-motivated condttions than under anonymous conditions. In recent studtes, we have found that the irnpression management scales, AM andCM, are more useful as response sets than response styles. They were designed for the purpose of capturing instructional setsto appear agentic or communal and they perform that task very well. These measures do not so has perform very well as styles, presumably because irnpression management many sources and is so sensitive to situational demands.10 To the extent thata response bias is self-deceptive, the motivation for bias is more trait-&e and therefore consistent with the definition of response style,
The factthattheoriesevolveisnotadeficiency of science.Indeed,its In&IS hght, responsiveness to new data can be seen as science’s greatest asset. the evolution of constructs underlying SDR should be viewed as inevitable rather than distressing. At the same h e , science should exhibit net progress rather than veer haphazardly. The ideas about SDR presented here are the result of such progress: They were founded on and developed &om earlier work. In particular, the earlier writings by Messick (1991; Damarin & Messick, 1965) were a necessary precursor for many of the ideas presented here. For example, Messick‘s writings emphasized the necessity of demonstrating d e p a r ~ e - f r o m - r e ~ tinyassessing SDR. To this end,he S statistical analysisof partial correlations.That notion andthat method proved to be central to the development of our residuals method of d e t e ~ the ~ g structure ofbias in self-reports (Paulhus&John, 1998). Yet those earlier ideas could not account for all the newly-collected data. In particular, the new data required a more elaborate structural model of SDR. This finaltwo-tieredsystemincorporates a content-level (agencyvs. c o ~ u ~ o asn well ) as a process level (conscious vs. unconscious).All four typesof SDR wereshown to involvethedeparturefromrealitythat d i s t i n ~ s h e sresponse biases from content dimensions of personality.

Jal There is ample empirical evidence that the stnJCbJreofindtvidl dtfferences in Cognitiie abilities may be described in terms of a hierarchcal modelwith three strata (Carroll,1993; Gustafsson, 1988, Gustafsson & Undheim,1996;Messick,1992). From a taxonomic point ofview the herarchical approach has important advantages (Gustafsson, 1988), and it makes it possible to unite confltctingmodels that emphasize either one generalability(e.g.,Spearman,1927) or manyspecificabihties(e.g., Thurstone, 1938). But the herarchical approach also may have plications for the meas~ementof cognitive abhties, and for measurement in general, which so far seem largely unexplored. The purpose of h s chapter is to dtscuss possible implications ofthe hierarchical approach for measurement. Coan (1964) introduced the term r ~ e r e ~ ~ gtoe refer ~ e rtoa the ~ ~scope ~ of reference of a construct, or "the variety of behaviors or mental activities to which it relates and the degree to whch it relates to them" (p.138). Snow (1974) emphasized the referent generality of constructs representing outcomesofexperimentaldesigns,andMessick(1989)made frequent reference to the construct of referent generality in his treatise on validtty. "he idea that measures and constructs differ in referent generality has, of course, close affnity to the hierarchical model ofthe structure of individual differences(Coan,1964; Gustafsson & Undheim,1996;Messick,1992; & Jackson, 1996). For example, the construct general Snow,Corno cognitive abihty is more general than is the construct spatial ability, in the sense that the latter ability is only one among many abilities that may be subsumedundergeneralcognitiveabihty. Similarly, it is obvious that a broad spatial ability subsumesa large set of more narrowly defined abilities,

F u r t h e ~ o r e such , tests have had difficulties meeting the criterion o f “face ” when being scrutinized (e.g., Neisser, 19’76, Gould, 1981). an (1927) did try to solve themeasurementproblem through ment o f more pure g-factor tests. John Raven was thus inspired by Spearman to develop the Progressive Matrices test as a g-test. This test has met with considerable success, but it has not generally been accepted as an alte~ative tothe heterogenous intelhgence tests in practical work, and it has not generally been accepted as the measwe o f g in scientific studies. seems that Compared to Binet’s practical contribution, it thus an’s theoretical and methodological contributions have had less o f an impact during large periods o f the 20th century. It seems, however, that the 1980s and 1990s haveimplied a renewed scientificinterest in the ct o f general intehgence, and in Spearman’s work (Carroll, 1996; & Tapsfield, 1996). One reason for this revitalization o f theoretical interest in general nce is probably the growing p o p ~ a r i and ~ success o f nistic, biologically based, models to explain individual differences in general intelligence (see, e.g., Anderson, 1992; Brody, 1 e research conducted during the 1980s of intelligence that has restored thegfac u s ~ f s s o n ,1988, Gustafsso likely reason forthe in as a c ~ u l a t e da massive ~ o o f empirical ~ t oubiquitous f the imp dimension o f individual ,1997).

have been performed. In the American research the narrow factors have beenseenasbuildingblocksforthebroaderfactorsand the analysisis conducted from bottomgoing up, using what Gustafsson and labeleda higher order modelingapproach. In theBritish tradition the analysis has started at the top, going down, usinga ~ e ~ ~ e d ~ c ~ approach (Gustafsson & Bake, 1993). If, however, these S arecarriedthrough to yield ahierarchicalmodelwiththree levels, similar results are obtained (Gustafsson, 1997). There remains, however, an important conceptual difference between the two approaches. According to the bottom-up, higher order, m o d e ~ g roach the lowerorderfactorsareundivisible9 and thereis no direct involvementof the higherorderfactorsinthelower order factors. However, in the top-down approach factorsat lower levels in the hterarchy are automatic~yfreed from the variance due to the broader factors. Thus, the lower order factors are split up into two or more parts: one due to the lower order factor, andone due to the higher order factors.These two ways oflookingatthelowerorderfactors(i.e.,thelow referent generah factors) have, asw llibe shown below, irnportant implicationsfor how to go about measuring the factors.
iscussions about alternative models of the structure of abilities tend to so thereisneed for a concrete become both complexandabstract, example. In order to beable to discuss measurement issues in terms we also need an example, and I rely on the Holzinger and S (1939) study for both these purposes. This study certainly deserves muc more attention than it has gained so far. It seems, in fact, that this study, whichwasconductedinthe 1 9 3 0 ~presented ~ all the important results about hierarchical structures of ability that have been obtained in recent years. A secondreason for selecting this study for reanalysisis that it includes a large test-battery, which covers a wide spectrum of broad and narrowabilities. The test-battery was administered to areasonably oup (N= 301) of 7th- and 8th-grade students fromtwo Chicago sch These datathusprovidematerialfordiscussion about manyinteresting zinger, who wasan ~ e r i c a n ,studiedforseveralyearsatthe ~ ~ v e r ofs iLondon ~ withPearsonandSpearman.Afterre

The technique is described in great detad in Harman's (1967) book onfactor analysis. Table 5.1 presents the estimatesoriginally obtained by Holzinger and Swineford, and the results computed with the confirmatory nested-factor model. As may be seen, the results are generally quite close. The reanalysis of the Holzinger and Swineford data with a modern form of factor analysis thus gives excellent support to the original bi-factor analysis, and it supportsthehypothesis that reasoning is of central importance to general factor (see Gustafsson, 1997, for an extended discussion about the substantive implications of these hndings).

This model is closely associated with the nested-factor model, and may be ed an as extension of classical test-theory to deal with mdtidimensio Reuterberg and Gustafsson(1992)demonstratedthattheinternalconsistency measures of reliability (e.g., CronbacWs alpha) may be formulated in terms of c o n f ~ a t ofactor ~ analpc models,andthat re~abilitym e a s ~ e may s easily be computed from the parameters es in such models, Thus, given a factor modelin which a setof components is related to one common factor, the amount of true variance components is the square of the sum of unstan edfactor loadings

4 Gustafsson At fast sight these three propositions may seem to conflict with current king about measurement, which emphasizes u ~ ~ e n s i o n a l i and ty homogeneity as prerequisites for i n t e ~ r e t a b ~(e.g., t y Pedhazur &c Pedhmur S c ~ e 1991). ~ , I try to show, however, that there is little conflict, but that the notion of measurement at different levels of generality makes it necessary to elaborate the meaning of the concepts u ~ ~ e n s i o n a l iand ty homogenei~.
The fast proposition w li be exarninedusing measurement of general intelligence as an example of a construct with high referent generality. One way to create a heterogenous test is to use a simple unweighted sum of all the tests in the Holzinger and Swineford battery. Such a composite score would a p p r o ~ a t ean IQ score, or a score on a very heterogenous test. that standardized scores (i.e., z-scores) are summed together, the ed variance for the sum wouldbe 165.9.Accordingtothe fomula presented above no less than 127.0, or 77 YO,of the total variance isdue to G. Another way of putting this infomation is that there is a correlation of .88 (i.e., the square root of '77) between G and thetotal score. T h ~ sis a somewhat paradoxical result, given that theamount of relations between G and the individual tests are not p a r t i ~ l a r high. l ~ The s t a n d a r ~ e dloadings(i.e., correlations) range between .l4 and "76,but most of the loadings are quite low. Often the relation between the broad factor and a test is, furthermore, hgher than is the relation between the Gfactor and the test. However, there is a rather obvious reason why the Gfactor is the dominating source of vakiance in the sum of scores, and it is that it is, to some extent, present in every test. According to the fomula presented above the contribution of a latent variable is a function of the square of the number of variables to which it is related. Because the general factor is present in every one of the 24 tests it gets a weight, as it were, of =I: 576, whereas the Gv-factor, for example, to which only 4 tests are Gv to the vaxiance in ts a weight of 16. The con~bution of the sum of scores is 3.1, or 1.9?40. From GC(5 tests) the c o n ~ b u t i o nis 8.7 (5.~?40); from Gs (4 tests) it is 3.1 (1.9?40) to Gs; and from Gy (6 tests) it is 6.4 (3.9yo). "hese results thus show a striking domhance ofthe G-factor in the sum of scores, and quite limited conttibutions from the group-factors.
~easurementFrom a HierarchicalPoint of View 85 e influence from the residuals also is very much reduced in thesum, and together they only accountfor 6.9% of the variance. It is i n t e r e s ~ gto compare the properties of the totalsum of scores as a measure ofGf with the properties of the Gf-tests. The single bestGf-test is the S E R C test, ~ ~with a loading of .76 on G, This implies that about 58% of the variance in this test is due to G, and it seems that this is about as high as it is possible to get with a single measure (Gustafsson, 1998). The other Gf-tests have loadings on G around .6, which implies that no more than some 40% of the variance in these is due to G (orGf). However, a sum of scores on the five Gf-tests in the Holzinger and Swineford battery hasavariancewhich to 76% isdue to Gf, and this isclose to whatis obtained from the entire testbattery. Such a score has a better face validity as a measure of reasoning ability than has the sum of scores on the entire testbattery, but it still would be derived from quite different types of tasks. It may, in passing, be noted that these results explain the success of Binet’s approach to measuring general ability with heterogenous tests, as compared to the relatively modest m o u n t of success met by Speman’s attempts to measure general intelligence witha single Gf-test. The total sum of scores on the test battery thus is a fairly homogenous measure of G, and also of Gf. The fact that a heterogenous mixture of task all typesmayyieldafairly pure measureofasingleability,much the colors yieldswhite,is not easilyrealized, and it certainly i us from an ocularinspection of atestbattery.Heterogenousteststhusare seriously lackingin face validity.It should, however, be emphasizedthat the tion demons~atedherehasbeenidentifiedbefore. Thus, H u m p ~ e y s(1962,1985)argued that measurementofgeneral with heterogenous tests, because such tests do ~ t ~ ~ g isebest ~ c done e provide a homo~enousmeasure of general intelligence. It also may be pointed out that a similar line of reasoning as that used here can be applied to explain why the general factor isso highly predictive of performance over a wide range of situations. Although any single task performed in school, on the job, or in daily life has a low relationto G, the fact that there are so many tasks on which performance to some extent depends on the general fa r explains why, in the long run, there will be a relation between aggr measures d performance of a d test perfo~anc~.

Bake, 1993).Accordmg to this model the observed variables are exchangeable indcators of the latent construct, and there is only a probabilistic relation between the observed and latent variables. For a construct such as general intehgence such a reflective, “open,” model seems more appropriate than a componential, “closed,” model. These subtletiesaside, it seemsthatconstructionofheterogenous measures is a wayproblem the of of construct underesentation in the meas of high referent generality constructs. problemofconstruct-irrelevantvariance,which is the other major t to construct valldity discussedby Messick (1989), does not, however, to be a major problem in a well constructed heterogenous m e a s ~ e , a more or less because of the gation effects, However, when homogenoustested to measure a highgeneralltyconstruct,suchas when the Raven Progressive Matrices Test is used to measure the &-factor, e problem of construct-irrelevant variance, in the form of test-specific variance, seems to be the major threatto validq. VVhen a low generality construct is the intent of measurement ~ ~ e y , 1991)construct-irrelevantvarianceseems to bethemajorproblem, but now c o n ~ b u t e dby more general sources of variance. At least this follows if a reflective,hierachcal,measurementmodelisassumed,because to such a model variance from high referent generality constructs contribute variance in the measure. If the measure is inte f the low referent generality construct only, the variance due to neral constructs takes theform of construct-irrelevant variance. eral sources of variance are only rarely conceptua~edin terms of -irrelevantvariance. It is,however,interesting to observe that e (1951) inthechapter on reliab~tyin thefirsteditionof 6~~~~~~~ ~ emade a classification ~ of~sources of variance ~ in test ~ scores in terms of referent generality, from neral to specific, and in term of lastin~ess.”his model is close to the on resented here, and it follows construct is in the focus of interest, variance f variance would be irrelevant. t measures of low referent erality constructs may capture urcesofvarianceis, fo ately enough, often realized inte~retationsof fmdingsismade. If, for example,a study establishes a correlation between a measure of spatial ~isu~ation ty and reading comprehension performance, the inte~retationwould cally not becouched in termsof,say,thedemands on spatial ation abilityby the processing of letters and symbols of punctuation
Measurement From a Hierarchcal Point of View 91 asfiguxalelements. A more reasonable interpretation would be that the correlation is accounted for in terms of an unobservedt h d variable, such era1 cognitiveability,whichisrelated both to performance on the visua~ationtest and the reading comprehension test. Thus, as long as measures of the more general abilities are included,the construct irrelevant variancemay be kept under control, and even when the more general sources of variance have not been measured they may be brought in via theoretical deliberations. But much may be gained if we also conceptualize the problem as a problem of construct vall&ty, because this wouldmaketheinterpretationalproblems more obvious,and it would stimulate development of appropriate methods of controllingfor the more general souces of variance (cf Gustafsson& Snow, 1997). Before leaving this topic it must be emphasized, however, that the line of reasoning presented here is meaningful only when the measures of low referent generality constructs are interpreted as signs (Loevinger, 1957) of unobservable abilities. If the test scores instead are seen as samples from a domain, it does not make much sense to &vide the variancein performance into sources of chfferent degrees of generality. Thus, in this case we haveto regard the performance measuresas measures of an un&visibleconstruct. Let me, finally, make a few comments about choice of a hierarchical measurement instead of a more traditional measurement model. It must, thus, be emphasized that compared to an oblique measurement model a hierarchical model is more restrictive, and it is based on an additional set of assumptions, Thus, ifthe hierarchcal modelfits the data, and the assumptions are not being violated, sucha model is to be preferred because it is more informative than is a less restrictive model. The problem is, of course, that it is not always clear which assumptions are imposed,and how theymaybe tested. The ordinary fest-order factormodel for relations between observed and latent variables an is additive, linear and compensatorymodel,and a higher order modelimposes the same assumptions for the relations between higher order and lower order factors. , Normally, however, a factor analyst does not test these a s s ~ p t i o n s and carrying the factor analysis into the hgher order realms does not imply any increased concern with these problems. In future work these issues should, however, be given more attention. The measurement issues discussed here are hplications of a particular theoreticalmodelofthestructureofcognitiveabilities,andif this theoretical model is not accepted, these measurement implications w i l l also or be c h ~ e n ~ e In d . fact, the question whether general intelligence exists

A reader may well wonder how I came to explore the field of personality en that in recent years I have devoted most o f my efforts to the structure of cognitive abhies. Several yearsagoIwas asked to review for ~ o n ~ e ~~ ~ ~ co r~ aalarge o~Z O volume, ~ I ~ ~ e ~ a ~ n aI ~ n ~~e Z ~ ~edtted e ~ c e , bySaklofskeandZeidner ~ a n d ~o fo ~o ~e r ~ o and th this volume,SaklofskeandZeidnerhoped to promote the of personality andintelligence as fieldsof research. In my review 97), I noted that the contributors of essays in the volume often had difficulty in bringing the fields together, neglecting to point out sknilarities anddifferencesbetweenthem or ways in whichtheymight cooperate. Indeed, some of the contributors treated the fieldsas if they were h o s t completely separate. Few if any of them concerned themselves with comparing them, as they might have done, for exmple, with respect to the treatment of cognitive ability. In the field of intelligence per se, the development of multilevel or hierarchical structures has been a prevalent strategy. In the field of personality, intellect has often been treated as one o f the factors in a so-called Big Five model favored by many researchers. In any case, through reading and studyingSaklofske andZeidner's edited book with the hope of writing a competent review, I became aware o f a major controversy about theplace of the Big Five modelin personality research. This controversy has been brought to a head in various ways. First, there has been a long series of publications promoting the Big Five model by Costa and McCrae(1988,1992a5 1995;McCrae & Costa, 1987), who appear to be m o n g its major proponents. They (Costa & McCrae, 1985, 1989, a revision, and a b) have publisheda personali~questionnaire e er so^^^^ shortened form) based on the five-factor model (F I n P e ~ ~This o ~ .questionnaire has been widely used in clinical practice and researc k published the by American Psychological Association (Costa er, 1974) seeks to show how the FFM applies to the classi~cationandtreatment o f personalitydisordersand how it can be plement to the ~ i a ~ nand o ~~ ~~ ~a c~~ ~ ~a o~f ~~~e c ~a Z ~ a rders ~ ~ ~ - I I I ~ ~ A m Psychiatric e ~ c a n Association, 1980 Several - acked reviews in the ~ n n RePiew ~ a o~ j~ ~ 6 ~ 0 inf & Pincus, 1992; Ozer & Reise, 1794) have giv highly favored basis for the analysis o f personality; only the authors of the most recentof these reviews, Butcher and Rouse(1996), are strongly critical, presenting various ents and empirical evidence *

According to them,cc[m]any reco Five-Factor Model as too superficial to help much in clmica1 assessment, which requires more refmed and broadened personality and symptom foci than are provided through the narrow lens of only five factors” (p. 103). Only in later phases of my literature review did I come across the most usefd references I have found: edited volumes by Strack and Lo (1996), the former devoted to dtfferentia~g no alities by means of various trait models, including the Five, and the latter expressly concerned with defending the five-fac its critics. My only complaint aboutthebook edltedby the authors neglect to say enough about possible criticisms ally, an impressive treatise on personality (Hogan, Johnson, 1997) devoted five of its 36 chapters to the Big Five model and d b e n s i o n s , and McCrae and Costa (1997b) suggested that the ~ve-factorpersonality trait structure is a human universal because it has been found to o c c u in a different languages, Indo and others. They even cite Edward Sapir (1921) as tured by the l a n ~ a g eone speaks, just missing ci Lee m o r f and the ‘TUhorfian h~othesis” (Ca~oll, In p r e p ~ my g review of the Saklofske and Zeidner v o l m e , I noted that Boyle et al., (1995) took a strong position against the FFM, in s t a ~ g that “both Cattell and Eysenck axe in complete a ~ e e m e n that t studtes of the so-called big five axe scie unacceptable” (p.431). of several other chapters in however, devoted considerable space to the FFM, ~ t h o u expre t c o n ~ b ~ t i to o nresearch in personality structure.

about personalityresearch,lookingat it from the standpoint ofexperiencewithresearch in the CO reah. First, I believe that there are lessons to be learned from that research, where the most successful and informative studies have come from efforts to findnewfactorsandtodeterminethestructureofnewdomainsin relation to domains already established. This means that in the personality field, more attentionneeds to bepaid to studyingthefactorsalready established-be they five, six, seven, or whatever-with the object of (a) whether any of the factors need to be more finely divided, and (b) d e t e ~ what g aspects of personality are poorly covered by those factors. This would presumably leadto the generation of lists of variables in the personalitydomainthatholdpromiseof r e v e h g newfactors or dimensions of personality.

110Carroll Costa andMcCrae(1992b) sought to measure the facetlevel in their se^ NE0 ~ e r s o ~~ ~av~e ~~ but to~ they ? established facet levels by itemanalysis techniques rather than by more powerful factor-analytic procedures. They chd, however, use factor analysis to establish factors at the domain level. Essentially, the expanded FFM presents a set offive second-order factors”or perhaps one might call them second-stratwz factors, analogous to the s e c o n d - s t r a ~factors in the cogmtive ability domain-in addition to a series of first-order factors, facets, and possibly alsoone or more thirdorder superfactors. The popularity of the FFM has prompted me to think that my work with .. eabihtiesmighthavebeenmoreexciting to the p s ~ c h o m e ~ c ty if I had dubbed the second-stratum factorsin the cognitive domain the ‘“Big Eight” --2F, 2C,2Y, 2V9 2U, 211, 2S, and 2T (Carroll, 1993, p. 626). But because I arn uncertain about how many second-stratum factorsactually esist in the coptive domain, I do not like to cornnit myself to some defnite number p r e m a ~ e l y . S d a r l yif, I were workingin the personality domain, I would not like to tie myself down to the idea that it contains only five second-order factors. From the hierarchicalperspective, it maybesaid that disagreements een Cattell (1957) and Eysenck (1970) in their theories of personality cture mightberesolved by pointing out that Cattellwas p ~ concerned with first-stratum factors-whatareelsewherecalledfacetswhereas Eysenck was concerned mainly withs e c o n d - s t r a ~or even thirdstratum factors. Treatmentof herarchical datais not limited to exploratory factor also be handled in c o n h a t o r y factor analysis by analysis. It can p o s ~ a t i n gandtesting factor patterns that specify different levelsofa hierarchy. This procedure hasbeenpioneered in the abilityrealmby ~ustafsson(1984,1988). It can easily be appliedin the personality r e a h , Since delivering my address at the September 1997 ETS conference, I have had an opportunity to consider further the nature of data typically found in the personality realm and to formulate factor-analpc procedures suitable for analyzing such data. I have been able to test my procedures by a p p l ~ them g to a dataset supplied to me by Digman, previously analyzed orted on in an article published by D i p a n and Inouye (1986; see
As noted previously, typical data in the personality research realm can be hierarchically stmctued, with facets at the first order and domaim at the

The Five-Factor Personality Model 11 1 second order (Goldberg &;Digman, 1994). In investigating simulated data, I have dscovered that when factor loadings o f facets on domains are generally higher than factor l o a h g s o fvariables on facets, as they can be in the personality realm, standard methods o f estirna factors that are vvOrthvvh.de to analyze may Specific~y,the number o f principal component roots that are greater than one may under these conditions give an estirnate, not o f the number of facets (fast-or~erfactors) ina set o f data, but o f the number o f (second-order factors) in the data. S d a r l y , the M o n t a n e ~and (1976) parallel analysis criterion may estirnate the number o f domains, not the number of facets, inadataset. These facts imply that at least some published factor analyses o f personalitydatamayhave been performed incorrectly and incompletely, in the sense that they have found l o a h g s for domains, but not for facets. It may be the case that a gven set o f data has ctors” (second-order factors masquerading as fast-order factors) S not inform one about facets (as true fast-order factors). To perform correctfactor analyses in the personality realm, it is ne cess^ fast to estimate the number o f facets (first-order factors) in the dataset. Myresults S st that the number of facets can best be es by det g the m a ~ u m number of principal factors that properly and easily relatively small number o f iterations) converge to a strict epsilon criterion o f .0005 for differences between successive CO estirnates. Further computations involve exploratory factor-analytic procedures required to perform a Schmid-Leiman o r t h o g o n ~ a t i o n ofactor f matrices produced at two ormore levels o f a ‘hierarchy. Given results of this procedure, c o n ~ a t factor o ~ analyses using LISIXEiL or other ap~ropriate computer progrms are done to refme the total structure and to establish significance of the structure and its elements. of this details of these procedures is beyond thescope chapter. However, the procedures may be dlustratedasapplied to the R i p a n and Inouye (1986) correlation matrix that was supplied by D i p a n . ~~~~~~~
The data consisted o f the matrix of Pearsonian correlations amon ersonality trait ratings (on %pointscales)made by teachers on 499 ade cMdren in Hawaii. According to Digman and Inouye (1986, p. 1l$),
e r e s u l ~ gdistributions of ratings"'may be describedasquasi nomal, nerally s y ~ e ~ and c with , verycomparable means andstandard ~onventionalprocedures in the exploratory factor analysis of this matrix wouldhave yielded five or possibly six factors, in that therewerefive ponentroots greaterthanunity, andthe MontaneUli and (1976) parallel analysis procedure for principal factoring t there were six factors worth analyzing. However, on the basis of simulationstudies mentioned earlier, it was conjectured that these estimates were for the number of second-order factors, not for the number of ~ist-order factors. Thenumber of first-order factors was estimated visionally by p e r f o ~ gexploratory f a c t o ~ gfor 3 to 15 factors, oosing the numberof useful factors as the highest number that provided convergence for estimated c o ~ u n ~ t iwithout es an excessive number of iterations, ~onvergencewas defined as occurring if the m a ~ u m dfference between successivelyestimatedcornrnunalities was lessthan .0005. To illustrate with the Digman and Inouye dataset, for 7 to 1 2 factors, convergence occurred with 9, 13, 10, 9, 14, and 49 iterations, respectively, For 13, 14, and 15 factors, convergence occurred with 165, 14, and 1 1 5 itera~ons,respectively. A conservative e s h a t e o f the number of useful factors would have been 11 or 12, but initially the estimate, 14, was more Liberal. Using~oreskogand Sorbom's (1989) LISmL 7 program, I estimated the ofactors ~ required~to fit the ~ ~ d e~ r l correlation ~ eg ~matrix; number of ~ thus, in the model parameter h e , PH=ST was specified. Initially, a pattern gs on 1 4 factors was proposed, based on thepattern o f high in thecorrespondmg ~ a ~ a x - r o t a t ematrix d computedby e~ploratoryprocedures. "his and some of the succeeding runs fded, fit the data when too many factors presumablybecause it was imp were specified. In successive runs, gutded the by modficatio~ indexes provided by the program, it became apparent that no more than 1 0 t-order factors (facets) could be supported. With 10 factors, the value of square with 796 degrees of freedom was 1774; Goodness of Fit Index (EFT) andAdjustedGoodness of Fit Index (AGFI) 348 and 3 1 9 respectively; andthe Root Mean Square Residual i n d i c a ~ grelatively small differences between the correlations reproduced fitted matrix and the actual correlation matrix. r e s u l ~ gfist-order factor matrix, with its second-order matrix of correlations amongthe 10 first-order factors, wasused in thebe *

114Carroll used here (N=I 496) was relatively large. Furthermore, in the fmal stage of the present analysis, the LISREL model was testedagainst a correlation ch of two virtually random independent samples (i.e., the oddandtheeven-numberedcases).Anynonzeroparameter found to be nt in either of these two samples was dropped and replaced by resulting factor matrix model, with 12 uncorrelated factors, is shown in Table 6.1. These factors, and their labels, are arranged to show their provenance in the Schmid-Leiman matrix that was used to start the computations. There were two superfactors, labeled SF1 and SF2;5 domain factors, labeled 1-0,-N, +C, -E,and +A that were interpreted as identical or similar to the factors in the so-called five-factor model, and five facets, labeled f3, f4, f7, B,and 212, concerned with highly specific varieties of behavior. It is interesting to note that the two superfactors accounted for by far the largest amounts of variance in the data, certainly more than the variance accounted for by the “standard” five factors. For this matrix, the fit to the data matrix was indicated by the following statistics: Chi-square with 759 degrees of freedom was 1370; GFI = 387; AGFI = ,860;RMSR = .084.
The factor matrix shown in Table 6.1 is not subject to the restriction whereby higher order factors are dependenton lower order factors, because the LISR.EL procedurechosenGsures that all factorsarec&npletely independent.
~ # t e ~ ofthe ~ ~Factom ~ t ~ Theo factor # ~ matrix shown in Table 6.1 indicates how much each of the 43 variables measures each of the 12 factors that were found to be significantly present in the data. That is, each row of the table specifies the “ll~ading’~ of the particular variable on each of the 12 factorslisted. The loadings,whethertheyare zero or nonzero, canbe thought of as the estimated weights of the factors in producing the scores or r a ~ g son a particular variable. Most variables are shown to measure severalfactors. For example,variable 8 ~ ‘ ~ o ~ l e d g e a b l has e y ynonzero ) loadings on three factors: .705 on the superfactor SF1, .524 on the domain factor 0 (“Opennessyy),and ,261 on facet f3. The problem is to arrive at a reasonable interpretation of the meaning of each factor. T~ically,this is done by comparing variables having high loadingson a factor with variables having low or zero loadings on the factor, seeking to induce some general rule or characteristic,variationsinwhichwouldappear to explain the contrasts in loadings. It should be noted that some variables were reflected in the process of factoring; the names of these variables have negative S
The Five-Factor Personality Model 115 refied to them. A negative sign thus means “opposite of’’; for example, ariable-13(-lethargic)istaken to mean “the oppositeoflethargic” or “active.” It may be useful to consider first the domain factors 3-0 (factor 2), -N (factor S), +G (factor 6), -E (factor lo), and +A (factor 11) and the facets associated with them. The symbols for these factors are found in the row, near the top of the table, labeled “Symbol for Factor.” The sign of the factor shows how it is oriented. Factor +Q is oriented positively in the scores on the factor indicate high degrees of “openness?” -Nis oriented negatively: high scores on the factor indicate 6cneuroticism.”In mostcases?thevariablesloaded on a arelistedinTable6.1intheorderof the algebraic es of their loadin on it.

It is hard to find an explanation for this ms to indicate that persons rated as ~ o ~ l e d g e a b and le “verbal” (with a large v o c a b ~ a ~tend ) , to be rated as less ccsensible’’ than otherwise. All variables loaded hghly on +Q also have hgh loadmgs on the superfactor SF1, to be discussed below. Factor -Nis interpreted as ‘CNotneurotic”; the loadings are relatively small.

Some of the variables with high loadings on -N(-12, “not rigid,” and +9, ~~a~aptable”) havehighloadings on SF1; others -43, “not restless”,and-19, “not outspoken”, have high loadingson SF2, discussed below.

The above analysis of the D i p a n and Inouye (1986) dataset, yielding 1 factors at threelevels of a hierarchy, appears to make sense. Becauseof the me tho do lo^ used to arrive at it, its results are rather dtfferent from most of what may be seen in the person^^ trait literature, except, of course, with respect to the “rec~rent”factors of the five-factor model. It is dtffic~tto tell whether the two superfactors found here correspond, for example, to any of the factors found by Tellegen (1993) or others who have expl personality traits beyond those specifiedby the F€!M. ‘Has is a question er smples of in~vidualsand variables s d a r to that employed here. at the inte~retationsof s~perfactorsSF inte~retationsof higher heredtfferconsiderably n (1997).

Accordmg to cus (1994, p. 82), characteristic q u e s t i o n n ~ eitems measu ension include the following: (On the positive side:) ‘ W e n I makea c o m ~ ~ e n I can t , always be counted on to follow though.” “1 am a productive person who always gets on thenegativeside:) “Somehes I’m not as thejobdone.”(And dependable or reliableas I shouldbe.” “I never seem to beable to get organized.” ut these items pertain only to observable behaviors. Could it be that more i n f o ~ a t i v eitems could be constructed around the possible motives, attitudes, and beliefs underlying these b~haviors?I am not sure whether research in personality hasadequately identified and listed the motives, beliefs, and attitudes that lead people to behave in conscientious or unconscientious ways. Nevertheless, a chapter on conscientiousn ty written by Hogan and Ones (1997) may be helpfid. Aeco them, conscientiousness isa complex scale. I t contains at least three themes: (a) control and lack o f impulsiveness; (b)orderlhess, tidhess, and m e t h o ~ c a ~ e s(c) s ; hard work and perseverance. (Note that two of these themes correspond to facets f7 and f8 in the reanalysis o f the Inouye dataset.) Hogan and Ones appeal to socioanalytic theory 1983) for an explanation o f these traits in terns o f their value for social c o n f o ~ t y ,the maintenance o f group structure, a hierarchy o f social statuses, and accountabdity and dependability o f group members. It might be possible, therefore, to construct scales whereby subjects could be asked ~ t group ~ sg~ c t u r eand the to rate the importance to them of m in~vidualaccountability of group members. Possibly this is heady done in certain ~ u e s t i o n n ~ efor s m e a s ~ honesty g and integrity. For example, subjects might be asked to rate each alternative in the fo~owin eed to do a job, it is important for me to get it done, because (a) people
The Five-Factor Personality Model 121 will think poorly of me if I fail,, (b)it is important that people be able to (c) things work out better if my planwhether 1 will getajobdone, c o ~ ~ e ncan t sbe counted on.’’ The intention would be to construct scales whereby one could detect the strength of the motives and beliefs underlying each of the Big Five (and other) factors. It would be interesting to factor-analyze these scales to see whether the factors would correspond in some way to the Big Five (or Seven) factors, or to a new set of factors quite different fromthe Big Five.
I seemanygoodfeaturesintheBigFivemodel. It hasbeenusefulin bringingagreement on important andrecurrentfeaturesofpersonality structure, and in organizing new research. But it is undoubtedly incomplete. g the question, “Is the five-factor model comprehensive from an e v o l u ~ o npsychologcal ~ perspective?’Buss(2996)opined, “From the current theoretical perspective, it is unlikely that the five factors alone w lli prove to be sufficient” (p.203). As I have already mentioned,, possibly the sixth and seventh factors of personality identified by Tellegen (1993) and others mustbeconsidered,andpossiblythereare still more factorsof personality to be elevated to second stratum statussimilar to that of the Big Five, Several of the Big Five factors seem overly complex, such that they need to be split into h t h e r factors. In particular, the factor ofOpenness to erienceseemsunnecessarilyambiguousandcomplex. “he workof A c ~ e m a nand Heggestad (1997) and Goff and Ackeman (1992) on the role of intellect-a what they call typical intellect.al engagement-needs to be fbrther developed. It w llibe important, also, in reanalyzing the factor-analytic literature on the structure of personality,to add information on facets underlying the Big Five and other second-order factors, such as those identified in the sample reanalysis offered here.

Thus, Fist we discuss abdities, then styles.
A new enthusiasm invigorated discussions of abihty
meas~ementin the 1970s. For the first h e in a very long h e , experimental psychology saw more than error in i n d i ~ i ~differences. u~ To name a few of themany con~butors:Estes (1974) proposed s t u d p g cognitivetestsascogmtive tasks; Hunt, Frost, and Lunneborg (1973) proposed using l a b o r a t o ~tests to clariljT the meaning of ability constructs; Underwood (1975) proposed dualdifferences as a cruciblefortheoryconstruction;Cha n (1976) investigated correlations among individual differenc on a memo^ search task, a visual memory search task, and SAT scores, From the ff side, Carroll (1976) showed how a n inf~rmationmight help us understand abfity factors and Royer Digit Symbol subtest of theWAIS could be studied as an information processing task. “he new look held a p ~ ~ c u l a strong ~ly attraction for those such as Bob Elaser at Pittsburgh and Dick Snow at Stanford?who had long tried to keep a foot in both the experiment^ and differ en ti^ camps. Finally, there were the freshly hatched new PhDs who developed these ideas into research pro ams of the& own :Susan Embretson, Bob S t e ~ ~ e rJim g , PeJlegrino, P Ackerman. But what began with parades down Main etered out in a hundred side streets. Some early enthusiasts-such as Earl dered aloud whether experimental psychology and differ en ti^ mightindeedbe ~ n d ~ e n t a l incompatible. ly Afteryearsof effort that produced, at best,a scattering of small correlations,Hunt (1987) ded: “It does not seemparticularly ffitfid to try to derive the sionsof a [traitmodel]ofabilitiesfromanunderlyingprocess Although this surely overstates, we believe Hunt’s t h e o ~ ” (p. 36). *
Using Cognitive Measurement Models 129 pessimism is closer to the truth than the naive optimismof many would-be bridge builders, whether they begin their efforts from the precipitous cliffs that ringthe tight little island of experimental psychology or from the beaches of the seexningly borderlessempire of differential psychology (cf. Cronbach, 1957). O f the many differencesbetweenthe two disciplines that couldbe discussed, we believe two are central. The first concerns how researchers thinkabout variation. Onecould CA it a difference in p ~ o s o or ~ h ~ cognitive style. The second difference stems from the fact that constructs in the two disciplines are defuledby quite different-often largely ~depen~ent-aspects ofscore variation. We discuss each of these in turn.
In his effortsto explain rift between experimental andevolutio biology,Mayr (1982) disshed betweenwhathe c ~ e d ~ ~tbin~ ~ ~ t i and essenti~~st tbin~ing. on and diversity are thestuff of population king; categories and typologies are thestuff of essentialist P o p ~ a t i o nthinking uniquely characterked the Darwin-Wallace natural selection, and later Galton’s studies of the inheritanceof mental and physicaltraits.Essentialistthinking, on the other hand,has experimentalists in biology, physics, and psychology. Ess p~osophy ting with Plato and Aristotle, asserts that observable characteristibjectsin theworld are butimperfectshadows of more perfectforms or essences. These essences aremore ~ e ~ a n e and nt therefore more real than the particular objects through which we conceive or deducethem. Variation amongcategory members reflects erroror im erfection in the manifestationof the essential form. sentialist b k i n g in psychology is perhaps most clearly evident in the al work of the Belglan statistician Quetelet and his concepti mean of a distribution o f a n t h r o p o m o ~measurements ~c as rev essential form of the average man ( ~ j en). ~ ~ Variation ~ e about themean reflected the actionof accidental causes,So Quetelet reasonedthat “there is [or no possibility of discovering anything abouttheimportantconstant systematic]causesin nature from the character of the error dis~bution, since this ~stributionis related only to accidental causes” (Hilts, 1973, 217).

sciphes do meet, or overlap. ~ o ~ d e p e n d e n of c erow a n n shows up in the interac~onterm. m e n consi
132 L o ~ a and n Bosma relations~pbetween learning and inte~gence,the most important cause of the interaction is an increase in score variation across trials, or what Kenny (1974) called thefan effect. Statistically, the fan effectoccurswhen true on the learning task is positively related to initial status on the learning .If initial status on the learning task correlates with intefigence, then g a i n s d also show a correlation. There are, of course, other possibilities, but this is a c o m o n scenario. Thus, the interaction term is the key to a better understanding of styles. ~nfortunately,both dfferential and experimental psychologists have been taught to dnirnize the interaction tern. Differential psychologists evaluate the dependability or reliabllity of individual drfferences by the proportionof the between-person varianceattributable to the person variance component (Cronbach, Gleser, Nanda, & Rajaratnam, 1972). A large person variance component and a comparatively small person X item interaction variance component are the goal. For the experimentalist, dfferences between conditions(or items, z) are judged relative to the size of the p by i interaction. But a s m d p by i interaction is not always the goal. Diagnostic i n f o ~ a t i o nabout how subjects solve tasks is most informative when the interaction term is large. In such cases, a single rank order of indviduals or of conditions does not give all of the interesting infornation. I ~ ~ u e n ~ a l developmental psychologlsts have long built their psychology around tasks that induce subjects to reveal important, preferably~ualitativedifferences in owledge or strategyby the type or pattern of responsesthey give. Furthermore,thesedifferences in owle edge or strategy mustthen be shown to generalize toother tasks or even to be indicative of broad competencies.Piagetwas partic~arlyclever in inventing or suchtasks for use with children. Siegler (1988) and others have continued thetradition, p r con~bution ~ ~ ofan information-processing analysis of a problematic situation is infornation on how subjects understood that situation or solved that task. Although such analyses usefully inform all subjects follow a u n i f o ~ test scoresevenwhen modelsaremost usehl for understan~g individual there are interesting dfferences in theway subjects S and in the strategiesthey deploy when attempting to er, most tasks studied by experimental psyc most tests developed by differential psychologists are not des such qualitative dfferences in type of knowledge or strategy use or to reveal them when they do occur.

Such comple~tiescomplicate but by no meansembargo tra between the two disciphes of scientific psychology. The main avenue of contactisthroughtasks or measurementproceduresdesigned to elicit rather than to prohibit (or obscure) dfferences in strategy or style, which brings us back to cognitive styles.

In Snow’staxonomy the conativ between the cognitive and affect domains, and represented by a motivationvolition continuum. Strategiesaremostlysubsumedunder the more e, dunder the affectiveitive-volitional pole and, to a lesser ~otivationalpole.Styles, on the other hand, ~ s ~ ~ uinore t e devenly across volition and motivation. One advantage of Snow’s scheme is that dtfferent style constructs (and their c o n c o ~ t a n tstrategies) are not operationallydependent on an overarching and rather conceptually nebulous CO itive-personality system, Messick took a somewhat dtfferent approach. m e r e a s Snow specific set of variables spanning the space, but excluding the s u p e r o r ~ a t e constructs of cogrution and personality, Messick (1989) preferred a greater inclusion of personality variables, He wrote: The human personality is a system in the technical sense of some ctions as awhole by virtue of theinterdependence of its parts..., Personality may influence the o r ~ a ~ a t i oofn cognition, the ~ e n s i o n a l i t y and stability of structure, and the nature and course of cognitive processes, as well as that of level of measured ability. (p.36)
Accordmgly,styles should betreated, not as CO behavioral variables related to personality, but as “ma ing personality structures in cognition, affect, and behavior” ~ e s s i c k , 1994, p. 133). An important question then is, ‘‘Do we include personality characteristics when attempting to assess styles,” and if we do, “At which point do weintegratethem into our meas~es?”This question canbe answered from either a top-down or bottom-up analysis, with the former h k n g p e ~ s o nto~ performance ty andthe later performanceto personality. From the top-down perspective, styles are consideredthe superor~natetier subsuming and ~stantiatingstrategies; most likely they do so ~ f f e r e n t i ~ y across situations and tasks, not unlike the personality constructs to which they are presumably affsed. Our tack dtake us through the bottom-up

By definition, styles concern not bow much but bow. As Messick(1976) observed:
tivestyles differ from intellectualabilities in a number of ways. . , Abilitydimensionsessentially refertothecontent of cognition or the question of what-whatkind of informationisbeingprocessedbywhat operation in whatform? . . . Cognitivestyles, in contrast,bear on the questions of how-n the manner in which behavior occurs....@p. G-9) Measures of styleshouldyieldscoresthatarebipolarandvalue ~fferentiatedrather than unipolar and value hected (Messick,, 1984, 1996). Messick proposed that we examine typical performance (see also Goff Ackeman, 1992) and use ipsative or contrasted scores to measure styles. There are a variety of ways to do ths. However, most attempts to measure cognitivestyleshaveinappropriatelyfollowedtheabllity-factormodel, which is bettersuited to valuedlrectionalquestions about unipolar, m a h a l perfomance constructs that ask how mtlch.

In Model I, all component processeswere self-termina~g,whereasinModel TV, all component processeswereexhaustive.ModelsI1and I11 ~ s t i n ~ s h eintermediate d cases. Performance of adult subjects was generally well fit by Models I11 or W. In later work withcMdren, Sternberg discovered that the performance ofyoungerchildrenwasbetterfit by modelswith self-te~ating processes, whereas that of older childrenwas generally better fit by models that hypothes~edmore exhaustive processing (Sternberg & Rifkin, 1979). Thus, modelscouldbeordered by amount ofexhaustiveprocessing required. Category score in this measurement model was then shown to be correlated withage or developmental level. ~ o m e ~ more e s than one h e n s i o n is required, such as in attempts to differences on cognltive tasks to abdlty constructs identified how theories.Siegler(1988) reported a niceexampleof classificationofmeasurementmodelsalongtwodimensionsmightbe accomp~shed.

Performance on each item wasclassifiedasbasedeither onretrievalofaresponse oron construction of a response using a back-up strategy. Students were then classifiedin one of three groups depending on the pattern of response correctness overall, on retrieval problems, and on back-up strategy problems. Sieglerlabeled theupsgood,not-so-good,andperfectionist students.Perfectionistswereents who exkbited good knowledgeof problems but set high confidence thresholds for stating retrieval answers.

The key assumption in both the Sternberg andR.ifkin (1979) and Siegler (1988) studies is that individuals can be classified on the basis of which of several models best describes their data. Once again, this is an essentialist or typological way of thinking about the issue. When tasks admit a variety

A s my engagement with the topic of cognitive styles approaches the 40year mark, I am compelled to acknowledge that the peak of activity and interest in the field was reached some years ago, with a steady decline since that time. I a m sure that Sam would have agreed with &IS assessment. It is quite dsconcerting to dscover that cognitivestyles, on whichonehad focused only a short time ago, were now relegated to historical chapters r e p r e s e n ~ golder approaches (Cantor strom, 1987; Sternberg, 1997). "he latter author claims that lus work on dunking styles (based on a theory of mental self-government) d rejuvenate the field. Clearly, more time dhave to pass before such a clairn can be effectively evaluated. Following my contribution to the CO styleliterature in the formof anencyclopeda entry (Kogan, 1994), d that it wouldbemyfmal word on the subject.Breaking the vow for the purpose of this volume would have been possible, but I could not see the point of it. I would essentially fmd myself recycling ideas that I had previously committed to print. It was evident that I had to move in a dfferent direction. ~atificationfrom the Throughout mycareer, I havederivedmuch construction of psychological measuring instruments tapping constructs for whch no such instruments existed or whereexistent i n s ~ e n t swere ossly inadequate. My initial engagement in such activity began before my arrival at ETS "he area of gero-psychology was quite underdevelope~at that time, and I accordingly took on the challenge of devising a series of i n s ~ m e n t sto measureattitudestowardandbeliefs about the elderly with Mchael Wallach, the Choice ~ ~ o 2000). ~ n In , collaboration Dilemmas Questionnaire was constructed Fogan & Wallach,1964),an enormously popular instrument that pervaded the research on risk-taking behavior (indvidual and group) for many years. With the move to ETS, and the influence of Sam and the prevailin more aware of the subtletiesand psychometric tradtion, I became complexitiesofmeasurement,and I would &e to believe that my instrument-cons~ctionactivities became more sophisticated. In the 1970s, duate students and I devoted much effort to the c o n s ~ c t i o nand on of the pictorial Metaphoric Triads Task, an instrument intended to assess in~vidualdifferences in metaphoric sensitivity in both children gan, Connor, Gross, & Fava, 1980). All of this is aprelude to the challenge that confronted mewhen I accepted a consultantslupwith the Lincoln Center Institute, an o r ~ ~ a t i o n
Assessment in the Performing Arts 149 to the fac~tationofaestheticeducationinpublic p r and ~ s e c o n d a ~schools. Jack Carroll (a former ETS colleague and a c o n ~ b u t o r to h s volunse) had served in the role and r e c o ~ e n d e dthat I take over as h i s successor. "he Institute wished to evaluate the success of theirp r o ~ a m , and it became evident to me that new and possibly unique ins~ments would have to be developed to accomplishthat goal. In the next section of this chapter, I describe the approach taken in the develop~entofsuchinstruments. The intent ofthepresentchapter, however, is to go beyond the particulars of the Lincoln Center Institute evaluation to assessmentintheperformingartsmoregenerally,andof p e r f o ~ artists g more spe~fically.
How does one proceed to studychildren'ssensitivityin the aesthetic domain? It is evident that we must place aesthetically relevantstimult before the child, and then evaluate the responses offered to such stimuli. There are a n ~ b e of r ways such a goal can be accomplished. At one extreme, one can offer the child musical or dance works from the appropriate standard reperto~e,and then ask a series of questions intended to tap his or her appreciation of such works. This is a direction that we deliberately chose not to take, given the prerniuns such a procedure would place upon verbal ability, prior arity, and c d ~ a lsophstication. Accorckngly, we adopted a more experimental trial-and-error approach to the c o n s ~ c t i o n of the required i n s ~ e n t s . Consider first the tasks developed for the dance assessment. We asked question: Are there aspects of dance of sufficient saliency and lend themselves to at least partial apprehension by children naive to the dance field? If so, could tasks inco~oratingthose aspects be pitched at a level of difficulty to allow for ~ e a individual ~ g ~ ~fferences?In the case of dance, we settledon tasks assessing(1) sensitivity to the affective and descriptive qualities inherent in dance movements, and (2) theabiltty to translate a dancemovement into a ~ o - ~ e n s i o n a l at isnot a floor pattern of dance steps). sational dancers were a v ~ a b l eto us, and a particular test item was represented by one, two, or all three dancers.

A highly relevant study emplopg expert and novice ballet dancers was carried out by Janet Starkes and her associates (Starkes, Deakin,b d l e y , &: Crisp, 1987). The dancers were shown a videotaped sequence of eight ballet steps without accompanpg music. In one case the sequence was selected by an experienced choreographer; in the other case, the sequence used the same elements randomly arranged."he dancers were required to reproduce the sequence of steps from memory. The results showed that the expert dancers did better at the task than did the novices, but only in the case of the sequences with choreographic structure. In addition, when music was added, the expert dancers' probabhty of recall showed a fwther increase. Of interest as well are the drfferences in the strategies of recall of the expert and novice dancers. The novices rushed to reproduce the sequences before the memories faded; the experts, by contrast, had encoded the movement sequencesthrough a processcalled mar~ng-where dancerssubstitute handpositions for foot andbodypositions. These handpositionsare reinstatedduringrecall,therebyfacilitatingretrievalof the sequenceof steps. Verbal labels are also sometimes assigned to the particular m o v ~ e n t sequences to enhancerecall.

In sum, it is evident that rote memorizing does not work for either actors or dancers, for the reason that it does not permit access to the deeper structure or meaning of the materialto be learned.
~ e ~ As we~depart o &om ~ the ~ study ~of the ~ SUS . inherently demanded by the performing arts, and move to the personality correlates of choo c performing arts careers, we cannot anticipate findings dstingui at statistical power. For we are essentially asking whether there are teristicsbeyondtherequisitetalents that contribute to choosing particularperformingartscareers. One canconceptuahze the issuein multipleregressionterms(i.e.,whatistheincremental contribution of personahty dispositions to choice of and success in the performing arts, ass that skills andtalentfactorsconstitutethestrongest predictors)~ Th also the possibility that the criteria employed-ehoice of a p e r f o ~ arts g career and success in that career-may have distinct causal nceivably, different quahties are associated with success in the arts than with choosing to embark on such a career in the first place. ~nfortunately,at the present h e , we do not have answers to these questions for the reason that the kinds of studies required to answer them have not been conducted. Investigators who study the skill components of the performing arts are not especially interested in personality factors an vice versa. A fkst approach, largely confmed to actors, involves the construction of a theoretically based ~ s ~ e onn which t actors are expected to achieve especially high scores. A good example is represented byMarkSnyder’s (1987) construct of self-monito~gwhosecentralfeatureconcerns the extent to which individuals are able to achieve self-control, and a c c o r h “are, in a sense, actors with a large repertoire of roles, d l t n g and able to work from a wide range of scripts; they cast themselves in many different partsinlife. By contrast, the lowself-monitor may belikened to the performer who hasthesame part ineveryproduction, partic~arlythe performer whose o m personality seems to provide the script forhs or her everyrole.”(Snyder,1987,p.186).

In a survey of dancers contempla~gretirement, Ellen Wallach (1988) vividly reported on theemotionally wenching qualityof the separation from dance,and H ~ t o and n Hamilton (1991) described a high level of suicidal ideation.

For fathers, 21% were professionals, 49% participated in the arts as amateurs. In the case of the mothers, the figures were 22% and 69% for professional and amateur ~volvements,respectively. In thls sample, actors and dancers were basicallysimilar in the pattern of parental artistic involvements.

In that war, the psychologists working on personnel selection andclassificationquicklysawtheneed to pickandstudyeachcriterion carefidly. The criteria must be vahd.

criterion. By its correlations with other measures, we can learn about the criterion. He distinguished between intrinsic content validlty for achievement tests and intrinsic correlational validity for ability tests. G d f o r d was more practical. By the second edition of his ~ ~ c b o ~ e t ~ et^^^ (1954), he offers not only a careful statement of the classical work on validity but also hints of things to come, with references to subjects’ motivationsand to responsesets.Regrettably, this editionornitted h ~ s citation, (found in the first edition) of Clark Hull’s 1928 book on A ~ t i t ~ d e TeJting. (That date is not an error. It was before Hull got into how rats learn.) H d identified three classesof aptitude criteria:product criteria, such as amount of work done; action criteria where one measures what occurs, such as the speed of a runner or the height of the bar in pole-vaultin finally subjective j u d ~ e n t sif, nothing elseis available. A major shift in. our thinking about validlty, and a major advance, came i c uc ~o ~ ~ efor ~ ~~ ~t ic o~n o~ ~ g with the work leading to the f=st T e c ~ ~ ~ Text$ and ~ i ~ g ~ ~ ~ t i published c T e c ~byn the i ~American ~ e ~ Psycholog.tca1 Associationin1954. “he authors’basicdistinctionsbetween content, concurrent, and predictive validity helped to structure our thinking. ’This committee report was followed by the Cronbach-Meehl paper on construct validity (1955).Those authors pointedout that the basicnotion of construct validlty cannot be expressed by a single coefficient.It is a pattern of results consistentwiththepatternspecified by the conceptu~ationof the construct. One basic statement in that paper deserves our attention and carefulthought: ““he investigationof a test’s constructvalidityis not essentially different from the general scientific procedures for de~eloping and c o n f k g theories9’Op. 300). That paper and the Tecbn~cu~ ~ c o ~ ~ e ndocument ~ t i o nstarted ~ a concern with validity of constructs andnot just with the validltyof a single test. But the spread of concern with validity did not stop there.

After studymg Messick‘s comprehensive analysis of construct validity, one would hesitate to undertake the d e t e r ~ a t i o nof the construct validity of any assessment operation.One sees why construct validation is seen as a never-ending procedure. One also speculates (or dreams) about the possibihtyofgoingback to nontest behavior, to opportunitiesfor appraising actual manifestations of the construct under na~alistic conditions: forget the ethical problems, forget the difficulties in obtaining samples that cover the construct domain, forget the diffic~ltiesin o b t ~ g reliable judgments of the construct from recordings. No, let’s forget that daydream and get back to measuring procedures where we, the authorities, can tellour subjects as subjects what they haveto do. Back to realtty. With a bit of luck, our work on construct validity of meas~ementsand of foms of validtty in research designswill complement each other, so that we can fit the various piecesinto one big picture. As Cronbach and Meehl said at the end of their 1955 paper (and as I have quoted earlier), construct validation is essentially the general scientific approachfortestingtheories. In pursuing it, aredoingwhatcolleagues all along. our dunking about it may in other scienceshavebeendoing help us to understand better whatwe are doing. Anastasiwrotein1986thatconstructvalidationis a never-endin process. It is however, not a task for Sisyphus, doing the same thlng over a major problem in and over. And we are moving ahead. We have identified psychology, and that is thefist step toward solving it. Construct validity refers toa goal. It may be ad-o’-the-wisp, leadtng us farther and farther downa road. I say that because rarely if ever have I seen a completely executed program for establishing the construct validity of anythmg, an assessment procedure or a construct. Yes, construct validation is a never-endtng process, partly because the construct vahdation of one assessment procedure depends to some extent on the construct validation of other constructs and assessment procedures. To s m & e what this chapter has argued up to this point, there has beenadevelopmentfrom one looseconceptofvalidity to multiple by 1980, r n e a ~ ~ Validity s. is a constantlyexpandingproblem.Even Messick counted 1’7 usages and labels for kinds of validity. Those working on a singletestseek to increaseitsreliabilityandhenceitsvaltdtty, a reasonable assumption if one has some vahdity to begm with. But others

The studyofhumancognitionandthemeasurementofeducational achievement are beginningto cross intellectual and empirical paths. Current efforts to define the conditions of educational attainment with the integral use of assessmentsdemandanexplicitallianceofthesedisciplines. eresearchhasdescribedprocesses,strategies, and structuresof that contribute to competent performance and identified the characteristics of performance change as subject-matter competence develops. m s work is c o n t r i b u ~ gto a better under st an^^ ofwhat learning involves, to a theoretical and empirical base for m e a s ~ n gwhat has been learned, and to the formulation of methods for addressing certain aspects of the construct validity of performance assessments. Construct validity in a modem context of coptive process inte~retationwould imply that assessment situations be evaluated in terms of the coordination of knowledge and skills in a particular domain and the associated cognitive activities that underlie competent performance (Glaser 1981; h n , Baker, & Dunbar, 1991;Messick,1994,1995). Of critical importance is that " ..the level and sources of task complexity should match those of the construct being measured and be attuned to the level of develo ing expertise of the students assessed" (Messick, 1994, p. 21). In d, two aspects of the assessment situation merit attention: (a) the relationship between the goals of the task and the performance elicited by the assessment situation (i.e., substantive aspect) and (b) the relations~p

For example, high school students were askedto "describe the possible forns of en es of materials involved in growing a plant and explain M y related" (Lomask, Baron, Greig, & Harrison, 1992). A comprehensive, coherent explanation revolves arounda discussion of inputs, processes, and products such as theplanttakesinwater,light,andcarbondioxide. Through theprocess of photosynthesis,lightenergyisconverted into chemical energy used to produce new materials such as sugar needed for ; in addttion oxygen is given off (e.g., Gregory, 1989; Solomon, ,& Villee,1993). In developingtheir expla~ations,students makedecisions about whichconceptsare important and how these concepts are related, thereby reflecting their conceptual u n d e r s t a n ~ gof the topic.Althoughtheopportunities for explanation are apparent, opportunities for other activities such as planning, selecting, and or monitoring problem-sol~g implementing appropriate strategies procedures are lessso.

As describedin this chapter, e activity onto the relative demands for science content rocess skills forcescoherent articulation of assessment concepts and practices that are informed by knowledge of human CO and learning. Essential in t h ~ sr is r e c o ~ t i o no f the qualitative dfferences in performance that S egeesof learning andexperience with asubject matter. Explicit attention to these dfferences d: (a) enhance the quality of current practice for the design and interpretation of achievement measures, (b)enable the defnition and analysis of consistency and errorsin performance interpretation, and (c) suggest keyconsiderations f scoringperformance.In this chapter, weoffered a rk for these purposes. development of structwesto p d e the design and evaluation of performance assessments wli require re~nementof the framework described here. Consideration also needs to be given to specific understanding of the course of learning and growth of knowledge in other content domains, andtheelaboration of the particularcharacteristics of developing competence appropriateto these subject matters.An important endeavor to be undertaken for improved assessment is empirical research that demonstrates the&pact of changes in design features on the quality of served in assessment situations. Our work also has indicated d of analysis we propose is p ~ t i ~ a ruseM l y for evaluating scoring procedures and judpents of performance. We pointed to cases where perfomances have been overestimated or wherestudentsscored highly but essentially rnissed the concept involved. As Linn (1982) noted “. ..providing the evidence and logical analysis that supports the uses and interpretations of test scores is the ~ n d ~ epsychometric n t ~ problem” @. 13). The message of this chapter hasbeen that such evidence can be derived from consideration of cognitive activity in relation to the content and process skills of the subject matter. Still to be considered is the use o f theories o f human performance asabasis for the systematicdesign o f performance assessment. .

A brief overview of theETS Gender Study w lliprovide usefid contextfor my remarks. oup of ETS researchers undertook this study for three reasons. We hoped to help clarify someconhsing fulhgs regarding gender differences; werealized that testing organizations need to know more about fairness issues in order to cope with new foms of assessment; and we believedthat a carefid study of gender difference and similarity would provide a usefid template for stadyhg fairness issues generally. T h ~ was s a 4-year study involving estensive review of previous work and quite substantial data assembly-about 1500 data sets involving some 400 tests and related measures of esperience, attainment, and proficiency. Our review of previous research convinced us that observed patterns of gender difference are distorted by three confounded effects: construct differences, sample differences, and cohort differences (i.e., chfferences by grade and year). We focused especially on large, nationally representative samples in order to better disentangle the construct, sample, andcohort effects. l93

That does not necessarily mean that test use is the stage of the assessmentprocesswheredecisionsare most likely to affect group differences. If there are limited test options to consider, then the decisions most likely to bear on testfairnessmustcomeearlier. Test designis a natural placeto look, because we design tests with a use in mind. There was a h e when the user typically decided whether to test, which test to use, and whether it was valid for the purpose. That is still true for some types of tests, but for the most important present-day educational tests, the options as to construct choice lie mostly in the design stage. We do notusually build several different high-stakes tests and then expect users to consider carehlly the utility and consequences of each test, and decide" as independent practitioners-whichtest to use.Wedesign tests with anintended purpose and populationin mind.

In large measure, westill use old-fashioned expert j u d ~ e n t in writing sensible items, and then apply quitemodem statistical techniques to assemble tests and to see what we have. In educational testing certainly, constructs are complex. Even in relatively homogeneous tests, the tested construct is layered with latentskills and knowledge bundles. We try to design test constructs by deciding what should be part of the construct and what should not, but these decisions are certainly not based skills involved or what S to on sure knowledge of the cognitive construct irrelevance may lurkintheassessmentformat.

C ~ nand~Tash. ~ In ~ this ~ chapter, ~ s the term construct encompasses characteristics that are c o m o n l y classified as coptive, focusing more s p e c i f i c ~ yon educational achevement. A construct, here, is an ability (i.e., is a human characteristic required for successful task performance). At the shplest level, these constructs can be identified with capacities to perform classes o f tasks defined by task specifications. Because they must enable more thanasingle task performance, the concept implicitly follows from the formulation o f an equivalence class o f task implementations or reakations, all of which require possession o f the sarne a~~~~~ construct for successful performance. However, in order tobe an ability,ahuman characte~sticmust not only ~fferentiate successhlfrom unsuccesshl task p e r f o ~ a n c e but , must also apply to some tasks and not to others. "hat is, everyabdity must be defmed so that it subdmidestasks into two groups: those to which that ability applies and those to whch itdoes not.
Validity of Constructs Versus Construct
~ a ~ i nGoah g and Taxk ~ e ~ o ~ a ~ In c eorder x . to comprehend achievement constructs, wemustlinktaskperformances to the learning goals they instantiate. To do this we must distinguish learning goals from teaching specifications. Curriculum is usually defmed in terns of the goals that are to be addressed by a learning system. Such goals refer to what is desired or intended to be learned by students (i.e., what students should become capable ofdoing after completinginstruction). In contrast, teaching specifications,whetherphrased in terns ofsyllabi, lesson plans, or specifications for learning activities, address what instruction must, should, or may take place. These specifications are often phrased as guidelines and linked to goals, but theyusuallytake the forn ofexamplesofrelevant instruction that are not explicitly analyzed in terns of the total set of goals. In short, we frame educational goalsin terns of abdlties to be acquired, but we frame instruction in terms of activities (tasks)to be carried out. During thls century, student learninggoalshaveincreasinglybeen phrased in psychological terns. That is, doing has been defmed in terns of ~ ibecome ~~ terminoloped as knowledge, task performance and c a ~ a has SM, or ability. Teachngspecifica~ons, on the other hand,areusually phrased in socialorganizationalterms,Theyfocusonactivities,mostly defmed in terms of what teachers should do with students; less frequently, in terns of student participation in instruction. Thus, although goalsrefermostdirectly to the attributes successful students should come to possess, the operational focus of goals is actually the activities in which the students participate. Obviously, these activities should be selected or created with the goals in view. It is these activities (lessons, tasks) that are intended to promote or assess the learning of the intended capabilities. The #nit or entity for which goals are established is therefore some kind of learning activity (or part or one, or an a g g r e ~ t eof several). These units range from an entire school system’s hll instructional program through those mounted withln it for a school, a class, a course, a lesson, a test, or a single task. Thus, goals are ablltties or capabilities, which students are intended to acquire. The structure of interrelations among goalsis complex. First, some capabilities are prerequisite to others. That is, some specific learnings must take place before others can occur. (This is not to say that in any curriculum there are not arbitrary orderings of the skills to be acquired, only that there exist some abdlties that cannot be acquired before certain others.) Second, capabilities are usually thought of as groupable, that isclustersof

Two UJeJ$‘ ‘ ~ o n J tIn~ the c ~ psychometric ~~ literature, the term c o n ~ ~ ~ has been usedin two ways for two different purposes:
to namethe psycholo~calcharacteristicsactuallyestirnatedbyanexisting test scoreor other measurement. 2. to name thepsychologicalcharacteristicsthat test a score or other ~easurementis intended (“designed”) to measure. 1.
Thus, the first purpose isusually to fmd out what a test score actually measures. For example, does this score labeled ~at~e~at~cal~~ob~ actually measure that ability or how should h s ~ a t ~ e ~ a t ~ c solving al~~obl score be interpreted? The second purpose is usually to orient the test design process so that the resulting measurement wdl be interpretable as planned (e.g., develop a measure of ~ a t ~ e ~ a t ~ c a l ~ ~ or ogiven b ~ ethis ~ definition sol~~ng ~ o b lthat e ~ theJ test o ~ score ~~~ resulting g, from the of ~ a t ~ e ~ a t ~ c a l ~ assure development process adequatelycorresponds to it). These two purposes are obviously interconnected. From my perspective, a targeted development process should be iterative (i.e., test items are drafted, tested, and revised iteratively through a sequenceofstages.Eachofthesestagesinvolves, during testing, an assessment of what each item measures and whether it matches the target). In the original formulation of construct valichty (Cronbach & Meehl, 1995), the nomethetic networkofinterrelationsamongobservableswas conceived asdynamic, that is, measurementschangedovertime so that validrty would change as measures were modrfied and new observables were added. Thus, from my perspective, the intent (dynamic) aspect of construct validty aswellas the actual (static) were built into the concept from the nning. The point I want to make here is that the word con.rtmtis used in a test the measurementliterature in two ways?ascharacterizingwhat measures (e.g., intelligence may be what an IQ test measures, but we need to identify more precisely whatthat is versus iteratively improvingboth the construct and its measures, e.g., how well does the SAT9 problem solving score measure problem solving using the New Standards construct d e ~ ~ t i o nThus, ? ) construct validtty has both a static and a dynamic aspect: 1. What does h s score measure? vs. 2. Does h s score measure what we want it to?

However, the criteria for what is included in a scoring record are quite varied.As an example, in a multiple-choice task, only the response category chosenby the respondent is recorded.

The specifications of the constructs to be measured by a test would seem to be a necessary prereq~siteto its construct validation, Performance ent has been characterized as being more “authentic” than aditional modes of assessment. As Messick (1994) asserted:
~uthenticassessments aim to capture a richer array of student knowledge than is possible with multiple choice tests; to depict the processes and strategies by which students produce theirwork to align the assessment more directly with the ultimate goals of schooling; and to provide realistic contexts for the production of student work by having task and processes, as well as timeandresources,parallelthose in therealworld.(Arter & Spandel, 1992) essick(1989,1994)discusses two majorthreats to validrty for tests enerally and performance assess~entsin particular.

To leave out aspects or parts o fm a n c e the extent that specific psych processes underlymg performance characteristics constitute part desired construct, traditional test speci~cationsand test specification categories may lead to serious construct underrepresentation in the tests for which theyareused. This is the case by matching each task in because the content o f the test is either (a) e~az~a~ed the test to the categories and ev~uatingthe resulting drstribution of tasks over categories, or (b)~~~~e~ by specifymg &IS distribution. To the exte that the categories are inade~uatelyor incompletely characte~zedwi respect to the desired constructs, a test will appear to be more valid than it s e nconstructs t or construct aspects. is, and will a c t u ~ y u ~ d e ~ e p r ekey ey, Petit, Mapus, and Atash (1995) have identified a number o f ance task characteristics ~fluencing orreflecting process that are not accounted in usual content specification categories.

g to specify here all ofthe aspects of process and performance ninimize construct underrepresentation through adequate specification of construct categories, clearly the supplementation of tra~tionalcontent descriptions with additional information of this type on the character of the desired construct would likely improve the fidelity of the assessment. Fidelity here means validlty in the sense of match between constructs assessed and constructs desired. At the level of an assessment (task, form, test, i n s ~ e n tetc.), , h s concept denotes the match between the desired mixtureof constructs fr the domainand the mixtweproduced by the task score or task score egation d e f i g the test score.At the levelof fidelity denotes the centralityand scope of the constructs ed in the particular t a d score to the overall mixture desired for the test or subtest score, As such, task fidelity rnight also be called task quallty. e United States, the educational reform ~ o v e ~ e has nt of perfomance assessment and along with that has also ation of “content standards” to guidecurriculumand assess~entdevelopment. In assessmentterms,these standards canbe viewed as a p p r o ~ a t i o n sto content specifications, because they provide categories for the classification of content and performance. Viewed in this way, they do not suffer from some of the defects of ~a~tional specifications. First, they are not simpleclassificationsoftasks or items.

Itisfurtherenhanced if thecommentaryincludes discussion of the qualities and characteristics of the worky and is annotated with reference to the content and performance descriptions to show how the work illustrates the descriptions. Once samples of student work and commentaries are included in this way, becomes it apparent that their role extends well beyond exemplification.Theyformanessentialpart of thearticulation of the standard itself, since it is only bough cross-referencing to the samples of student work and their accompanying commentaries that the content and performancedescriptionstake on sharedmeaning. In otherwords,the samples of student work anchor the standards in a way that allowsfor their consistent interpretation(NSI?, 1995). It should be noted that “samples of student work and accompan~ng commentaries” means, in t h s context, (a) full specification of the task the student was to successhlly complete, (b) inclusion of the performance record (i.e., student work), (c) evaluation of work against both the task‘s performance goal and its measurement goal (i.e., the intended construct). See Wiley (1991), Haertel and Wiley (1993), and Wiley and Haertel (1996) for a fuller discussion o f these concepts. Thus, two ways of more completely specifymg and anchoring construct categories have been identified: specifications o f additional task characteristics reflecting process and performance aspects of tended constructs Pgney, Petit, Mapus, Atash, 1995) and inclusion o f samples of student work and accompanying c o m m e n t ~ e s(NSP, 1995).

In order to vahdate a performancetaskanditsaccompanyingscoring rubrics in terns of intended constructs, several approaches may be taken.

Because the purpose is to validate perfornance tasks by inferrhg which performance capabilities they can be used to assess, these activities help accomplish this goal. n e second method is to gather additional data directly from the respondents about theirperformance.

An rule is a function that maps a pattern of scores across tasks score for the taskcollection. For example, in traditionalmultiplechoice testing,testitemsareeach scored only once as correct (scorezl) or incorrect (score=O); the total score for a collection of items is usually shply the sum of the item scores. In performance assessments, rubric scores for tasks are ~ i c a l l ygraded scales of perfomance, and s ~ scores amay ~ take the form of task mappings, (California Learning Assessment System [CLAS], 1994;Wiley,1993).

A task collection may therefore have more than one In general, there mall be a distinctaggregationrule for measured by the task collection. Because tasks may have more than one scoring rubric, the number of score types potentially entering an gation rule is equal to the sum-”over tasks-of the number of rubrics for eachtask.Anation d e groups task perfomance patterns all the patterns in a group considered as into score pattern g o equally informative about the construct.

So if a task has a rubric for a construct we defme a rubric indicator (Utc ‘1, if rubric for c; =I: 0, if not).

ach the construct validity of a test score, we are tahng a of that score by the very nature of the notion of c o ~ ~ t ~ c t . mplicit in the idea that a score can measure a construct, is a decomposition of the score into 6 0 plus other ~ (i.e., ~ S = ~c + 0). ~ Usually, ~ we ~conceive of e other as the discrepancy between the score and the construct. Sources of screpancies may be (a) errors of measurement-in the ~aditionalsense, entation (Messick,1989),(c)ancillary ab~ties ~ ~ e 1993) y , leading to construct989); i.e., invalidity).Note that I am lump^^ ty with sources of lowered validityto constitute other or ~spectiveleads to theconcept that validity of measurements subconcepts. (1) The validtty of the The validtty or invalidity of the score construct. The notion hereisthat the ~aditional plies jointly to the construct being measured and to the score used to measure it. The analo is that of joint and c ~ n ~ t i o n a l
224Wiley and the validtty of the construct itself (i.) by V(C). I do no wish to imply by this that there must be validtty indtces suchthat V(S, C) = V(C)V(S/C), and whicharescaled &e probab~ties(i.e.9 0 2 V 5 l), although p o s s i ~ ~ t yMy . intent is only to allow separation of the evaluation of the validity of the score for the construct from the evaluation of the construct itself. These aspects of valldtty require more complete definition. The defition of the joint validity of score and construct, that is, V(S,C), is to my mind, the same as the defi~tionimplicitly used by Messick 1989,1994)and thus involvesall the validityaspectshe identi content, consequential). To understand the decomposition better, I defme the V ( ~ / C )aspect as the limited defmition of construct validity of a score focused on how well the test score measures the construct, (i.e., whether or not the score has construct-~elevant variance or construct underrepresentation). To better understand the eaning of by V(C), let’s assume s that the score validtty for the construct perfect.

The aspects of valldtty influencing ,C), under these condttions, and therefore V(C), enerally, are p r ~ a r i l y consequential. To repeat what I said in the in~oduction;this chapter has a twofold .First, in Test v a and~~ ~~ v ~~a ~~e ~ c(Wiley, d ~~ 1991), ~~ I~expressed ~ ~ and a reference for separating v ~ d i t y questions about test use consequences from those c o n c e r ~ g the relations between test scores and constructs.

I now find it less useful to s h q l y separate these perspectives and as this new perspective has evolved, ani n t e ~ a ~ now o n seems moreproductive.
Validtty is at base about interpretations. In the most ~aditionalsense (e.g., Cronbach1988,1989); (AERA,APA, NC ,1985) this inte~retationis of scores. I would like here, however,to propose an expansion of targets of interpretation in a validity frameto include constructs as well as scores.

though I wasquick to sayyeswhen Ann Jungeblutasked me to participate in thls celebration of Sam Messick‘s contributions to educational measure~ent,I must admit it is a bit in about issuesofvalidity,constructs,andvalues in this eople have contribute^ to the ref~ementof the S about validity.

Although it may not be evident from my remarks,I have learned a great deal from Sam. I am indebted to h for the support he gave me early in my career when I was at ETS. He always gave me encouragement and the freedom to pursue my research interests. In addltion to teaching me a lot about validity, Sam alsotaughtmesomemoremundaneandpractical things. For example, he taught me that an ETS Senior Research st (the title he held whenI was new to ETS in 1965) is obviously to a full professor because we always waited for him to arrive full 15 &Utes after the tirne he set for the start of a meeting. When he became a vice president, I learned that there is no university equivalent of that exaltedtitle,because no onewouldwait that long in auniversity setting. I alsolearned as edltor of the Third Edltion o f ~ ~ ~ c a t i o ~ a chapter by Sam wli certainly not arrive on the ~ e a ~ ~ r ethat ~ ealthough nt, li beclearwhen it does arrive that the editor’sdesk on schedule, it w contribution it makesismorethanworth the wait.Although I haven’t checked it, I am confident that Sam’s chapter is the most cited,and certainly the most influential chapter in the Third Edltion of ~ ~ ~ c a t i o ~
~ e ~ ~ ~ e ~ e n t .
Of course, there were good reasons people werewJUlng to wait for Sam to show up for a meeting just as there are for an editor of a book to be g to wait for a chapter. Most porta ant of these reasons is that the quality of his thinking on issues ranging from the mundane bureaucratic ones to the profound. Sam’s contributions to the discussion are consistently worth the wait. It is no wonder that when ETS has had a o n to offer, Sam problem or issue that required the best the o r ~ ~ a t i had has long been the person that every ETS President (Henry Chauncey, Bill Turnbd, Greg Anrig, and now Nancy Cole) has turned to for help. Thus, there was no answer other than ‘‘yes?’ when Ann Jungeblut asked me to participate in this celebration. I am delighted to be part of it. The focus of my chapter is on issues of values, constructs, and valicbty in the context standards-based assessment programs. I take as my starting point, Sam’s one sentence definition of validity in his 1983 chapter in the third edition of ~ ~ ~ c a t i o ~ awhich ~ Shepard ~ e ~(1393) ~ r edescribes ~ e ~ as t , the currently“mostcited a u t h o r i t a ~ ~reference e on the “Vahdity isan integrated evaluative j u d ~ e n tof the d empiricalevidenceandtheoreticalrationales support the a ~ and ~ a ~ ~ r ~ of~~ an ~t ree and n~c e eactions ~ ~ ~based on test scores or other modes of assessment” (Messick, 1983, p. 13, emphasis in original). This statement,
~
Constructs and Values in Standards-Based Assessement 233 which is the fust sentence of Sam’s influential chapter, is so packed with meaning that it took him 91 pages of an oversized book with relatively small type to elaborate the concept. As I’m sure is f d a r to most readers, Sam’s comprehensive defmition a two-by-twotablecorrespondmg to the ofvalidityiselaboratedin adequa~/approp~atenessand inferences/actions distinctions of the defition. The two rows of the table distinguish two bases of support for valtdity claims-theevidentialbasisand theconsequentialbasis that are used to support claims of adequacy and appropriateness. The two columns of the table distinguish between interpretations of assessment results (e.g., a ““strikinglackof the latest NAEP hlstoryresultsshowstudentshave knowledge about their heritage”, Innerst, W a s ~ g t o nTimes, November 2, 1995)anduses of results(e.g.,thecashawardsgiven to teachersin Kentucky based on increases in assessment scoresby successive cohorts of student). Although there is some disagreement in the field regarding the desirability of includmg consequencesas a part of validity (see,for example, Green, 1990; Moss, 1994; Wiley, 1991), there is broad consensus both with other parts of Messick‘s comprehensive formulation and with the importanceofinvestigationsofconsequences as part of the overall evaluationofparticularusesandinterpretationsofassessmentresults (Baker, O’Neil, & Linn, 1993; Cronbach, 1980; 1988; Linn, 1994; Linn & Dunbar, 1991; Moss, 1992,1994;Shepard, Baker,1998;Linn,Baker, 1993). Of course, a f ~ ~ a t i oof prirnacy n of validity based on a comprehensive framework is. one thing. Valtdity practice is quite another. Validity practice is too often more in keeping with outrnoded notions of validity that basevalidityclaims on a demonstration that testitems correspond to the cells of a ma& of test specifications or the demonstrationthatscores on atestarecorrelatedwith other relevant measures (e.g., teacher ratings, or another test administered at a later time). Although both content-related evidence and criterion-related evidence are relevant to validity judgments, theydo not provide a sufficient basisfor the kind of “integrated evaluative judgment” that Messick demands. Standards-based assessments currently being introduced in states around the country are frequently introduced by legislation that includes a requirement that assessments be “valid, reliable, and fair.’’ However, the approach to validation is often limited to comparisons of the assessment content to the content standards that are supposed to determine what gets

Before getting into issues specific to the validity o f assessments, it is useful to consider some aspects o f the standards-based reform contest that is the basis for the types o f assessments that are the focus o f my chapter. A l995 l of Education Panel on ~tandards-~ased report of the ~ a t i o n a Academy Education Reform described the vision of the movement as follows. The intentions of standards-based reform are best captured in the slogan ‘high standards for all students.’ Unlike previous reforms focused on the attainment of tminimum competencies, setting higher academic expectations is expectedtoensurethatstudentshavemorecompletemasteryof subject matter and the ability to apply what they know to solve real-world problems. Standards-based reform also reflects a strong c o d t m e n t to educational equity: The same high espectations are to be established for all students, even groups who have tra~tionally performed poorly and received watered-down curricula.~ c L a u g h& ~Shepard, 1995, p. xvi)
Values questions are evident in this characterization of standards-based education reform. So too, are issues about the nature o f constructs that assessments based on standards ~onsistentwith this description are intended to measure. The s m e curriculaandsamehighstandards for all students, although easy to accept at a rhetorical level, obviously may conflict with the desire o f parents to have the best for their children. The u~ poll (Rose, recently released annual Pht. Delta ~ a p p a / ~ a l leducation Gallup, & E l m , 1997), for example, reported that whileroughly threefourths o f the respondents approved e s t a b ~ s ~national g standards for m e a s ~ gthe academic performance o f the public schools ( 7 7 ~ 0 )an a p p r o ~ a t e l yequal proportion favored moving chronic “~oublemakers’’ all students does not include into alternative programs ( ~ 7 ~ 0Apparently, ). ~oublemakersin the minds o f the survey respondents or they don’t agree with the dual goals of the leaders o f the standards-based reform movement. Moreover, two out o f three favored ability grouping ( ~ 6 ~ 0 ) .though abilitygroupingis not, in p ~ c i p l e , consistent with the sarne‘,high standards for all students,?’ considerable experience inconsistent in practice (e.g., Gamoran & Berends, 1987; Value conflicts over the weight to be given to the e over acceptable or desirable approaches to achieving that goal provide
Constructs and Values in Standards-~asedAssessement 237 potential sources of confict regardmg the standards-based reform effort. These conacts arelessvisible,however, than value conacts over what should be emphasized in the standards and, therefore, taught and assessed. As is evident from the heated debate about the Voluntary National Tests, value conflicts about c o n s ~ c t sthat are to be assessed have considerable sahence. This is so, in part, because it is less socially acceptable to question the goal of equity than to question the vision of a &scipline such as hstory, or even, the less controversial ~sciplineof mathematics. The standards movement has pushed new concepts of the disciplines that generally d o ~ p l a ythe ac~mulationof facts and procedural skills in favor of conceptual understandmg and problem-solving processes. Mathematics was in many respects the lead chsciphe. It is almost a decade since the National CouncilofTeachersofMathematics(NCTM,1989) p u b ~ s ~ ethe d ~~~~~Z~~ and E ~ a Z ~ a tSi o t~ a ~ for ~ SchooZ r ~ ~athe~~t~c~ Although it is hardly the case that the instruction envisioned in the NCTM Standards has been inco~orated into the daily practices in most classrooms, there is little doubt that those standards have been in flu en ti^. They have receiveda great deal of praiseby politicians as well as educators, have served asa model for mathematics standards developed in most states as well as standards in other subject areas at the national and state levels, and are now routinely claimed to be a source of p d a n e e by textbook and test publishe~s. The broad support enjoyed for a number of years NCTM Standards was never there for some of the other content areas. The history and Englishlanguage arts standards, in particular, were subject to harsh criticism (e.g., ~ i e ~ u e l l e1994). r , As the NCTM standards have become more influential and as assessments designed to be aligned with the standards have started to make the constructs and values of the standards more explicit, however, the NCTM standards also have come increasingly under attack. This point is illustrated by the exchange in the New York Times in whch Lynn Cheney (1997)attackedwhatshecalled the f fuzz^ math” or “wholemath” encouraged by the NCTM standards and Tom Romberg (1997) defended the standards and the mathematics that theyenvision. That and other recent criticisms have taken place not only in the contest of the debate about the Voluntary National Test, but in the context ofseveral state assessmentprogramsand efforts to revise state content frameworks or standards.

Tacit knowledge can be used success~lly to e student work by consensus among experts, possibly using formal moderation procedures. More is needed than consistent if students and other novices are to understand what is the standard and hence be able to judge performances against the standard. The third method, the use of exemplars of performance that does or does not meetstandards,is usually institutedinanexplicit effort to c o ~ u ~ c a what t e thestandardsentail to a broaderaudience.“The exemplarsare not thestandardsthemselves, but areindicativeofthem; they specify standards ~plicitly”(Sadler, 1987, p. 200). Because there are innurnerable potential examples and a host of contextual and other factors that may influence performance, many exemplars are needed and a heavy inte~retationburden is placed on anyone attempting to infer performance standards from a collection of exemplars. Verbal descriptions attempt to provide explicit d e f ~ t i o ~of s performancestandards.Someverbaldescriptions m adverbs and adjectives to defme levels of performance ~ ~ ~ Other ~ c Q verbal ~ .descriptions rely on verbs (e.g., make.

( ~ ~ p b Donahue, e ~ , Reese, pmps, 1996, p. 42) Unlike the precision o f nwnencalcut-offs, verbal descnptions are “‘fuzzy standards.” Yet, it is verbal descriptions and associated exemplars that most influence interpretations o f assessment results, Hence, those descriptions and exemplars deserve much more attention in validation efforts than they usually receive. Three of the four methods described by Sadler are use plement and c o ~ u ~ c a the t e NAEP performance standards. Verbal descnptions, such as the one just illustrated, are accompa~edby numerical cut-offs that operationa~ethe perfomance stand~ds on the NAEP score and by exemplar items and student responses. Apparent &Sties between these different approaches to s ~ e c i perf0 ~ g ds sometimes arise and lead to challenges to the validity of the stand~ds.

Constructs and Values in Standards-Based Assessement criteria and cut scores required for a student to be at the “‘basic” level in hlstory, the ccadvanced” level in mathematics, or the “‘proficient” level in reading also make explicit how good is good enough and what is required to be considered excellent. In other words, it is through assessments that both content standards andp e r f o ~ a n c estandards become concrete. ecauseofthediversityofopinion on whatis most important for students to learn and what is legitimate for schools to teach, it is essential that the processofdevelopmentene the broadpublic so that the &verse range of views can be heard.

Neither the voluntary national tests nor important state assessments can escape this debate.Indeed, it isalreadyunderway. As Ravitch(1997a) noted, “the Internet ish stacked to favor ‘whole and to promote ‘fiafuzzy math’ (where the rightanswer,mattersmost) though she stated that she did n used the concern to argue forcehlly for Congressional autho~ationfor the v o l u n t ~nationaltestsandtheassignmentof responsib~ty for d e t e what ~ should ~ be assessed by the tests to a nonpartisan bo ed for the action by Congress to establishan expande~ Assessment Gove oard (NAGB) for this purpose.

the concept of a standardized measure as follows. “Standardization irnplies u ~ f o ~oft procedure y inadministering and scoring the test. If the scores obtained by different inchiduals are to be comparable, testing condtions ust obviously be the same for all. Such a r e q ~ e m e n tis only a special application of the need for controlled conchtions in all scientific observations” @. 23). Other well-knownauthoritiespresented sMar ts. Cronbach (1960), for example, emphasized the standar~~ation a standardizedtest as “oneinwhichthe edureanddefined procedure, apparatus, and scoring have been fixed so that preciselythe @. 22). same test can begven at different times and placesy’ Popular use of standardized tests often has other meanings. It may, for example, be the term used to refer to a published, m~ltiple-choicetest, but such characteristics are not fundamental to the concept. An essay test can have a relativelyhighdegreeofstandardizationofprocedures(e.g, instructions,timing,andscoring),whereas a multiple-choicetestcanbe a ~ s t e r e dinunstandardized ways(e.g., withdifferentinstructions, under different conditions, and with different time constraints). It is hardy surprising that u~formity of procedure would be emphas~edwhen the goal is fair and valid comparisons among indwidual test takers. It would obviously be quite unfair in the a ~ s ~ a t i of o nan essay test scored for content, spelling,andgrammar to allowsomejob applicants to typetheirresponses at a word-processorwithaccess to a ar checkerwhereas other applicants spell-checker, a thesaurus,and a were required to write their by hand without access to such resources. Tradttionally,it would also be considered unfairto allow one test taker 90 minutes to complete a test whereas other test takers with whom they are competing were held to a strict time h t of 60 minutes. Such ~aditionalnotions of standar~ationare being challenged with increasin frequency, however. The goal of including students in assessments who would have been excluded in the past because of a disability or because of lack of fachty in S raised questions about the essential and nonessential aspects of tion. This is fundamentally a values-laden construct validity problem. The most commonly requested and used variancefrom stipulated a ~ s t r a t i o nconditions in state and national assessments is extra time.

Constructs and Values in Standards-Based Assessement247 languages other than English. The plan for the 8th grade voluntary national test in mathematics, for example, includes a provision for the creation of a Spanish language version of the test. A number of states are following a s h d a r path. The expanded emphasis on adaptations and accommodationsthat allow greater n w b e r s of students to participate in assessments raise~ n ~ a m e n t a l issues about s t a n d ~ ~ a t i onot n just for thestudentsfor whom the variations in procedures are intended, but for all students. ~ n i f ofo ~ ~ procedureshouldberecognized as a means to theends of valihty, reliabhty,andfairnessratherthan an endinitself. Shplistic examples, such as being allowed to use eye glasses when tahng a test, make it clear that complete u n i ~ was o ~ never ~ the intent. Indeed, most people woul agree that it would be unfair to deny a person who wears glasses the use of thls a c c o ~ o d a t i o nwhentaking a test. SMarly, thereislittledebate or B r d e versions of a test. about the fairness of the use of large print Implicit in the allowance of such accommodations is the belief that they are not relevant to the construct being measured. Or conversely, the unaided visualacuity that may bute to variabhty intestperformanceisan ancillav abihty(Haerteln,1996) that contributes c o n s ~ c t - ~ r e l ~ v a n t variance to test scores (Cook& camp be^, 1979; Messick, 1989). In a s d a r vein, the decision to make a Spanish version of the 8th ade voluntary national test in mathematics is predicated on the notion atthespecificlanguageused for presentauonofproblemsand for c o n s ~ c t i n gresponses by testtakersinvolveslanguage skills that are ancillary to the mathematical knowledge and SMS that the test is intended to measure. Presumably the limitation to either English or Spanish rather any language preferred by a student is based on practical considerations of numbers and cost rather than principle. Note that the same decision was not made for the 4th grade voluntary national test in reading where the Departrnent of Education planprior to the transferof responsibility for the test content to NA called for thetest to beprintedonly in E Given that position, obvious that the measurement intent is not the abihty to read, but the abilityto read in English. It is worth noting that both the plan to develop a Spanish langu version of the 8th grade mathematics test and the plan not to do that adereadingtestwerechallenged.Advocates for lin ~ n o r i t ychildren argued that the reading test needs to be given in Spanish to allow children who have received instruction in Spanishto participate in *

On theother hand, the plan to givethe8th grade mathematics test in Spanishwascalleda “terrible idea” bythose who ed that “[s]tudents in American schools must learn to function in the ger society, which requiresknowledge of English lan~age” pavitch, 199?b, p.64). though the allocation of the likely effects on performance to c o n s ~ c t - r e l e v a and ~ t cons~ct- relevant sources of variance is str and noncontroversi~for some variations in a e (e.g., the use of eye glasses), in most cases there is uncer eis controversyaboutthechoice o f c o n s ~ c tshould it reading in English, doing mathematics in English, or should it be rea or doing mathematics in the language of a student’s choice? Secon is uncertain^ about the degree to which skills intended to be ancillary (e.g., g on mathematics a test) influenceperformance for different Th evidence to support or refute aspecific allocation o f variance as relevant or irrelevant is generally weak or none~stent.

Would a similar increase in tirne makethe test a more valid measure of those intended skills and knowledge who were not di osed ashavinga le relevant to judgments validity and fairness of the acco answer to both questions is yes, then it may be consid extra h e only for studentschagnosed to have a disability although it would enhance the validity of the measure for those students.

test fairness has evolved. They argued that the concept of test fairness was made more complicated by the addition of requirements that the test be “unbiased” and that the uses of test results be “equitable and just.” ”hey went on to make the case that “fairness is animportant aspect of validity ., .” and that “[a]nything that reduces fairness also reduces vahdity” (p.6). They concluded that “test fairness is best conceived as comparab~tyin assessment; more specificallycomparablevahdity for allindividuals and oups” @p. 7-6). Equating test fairness with comparable validity for all individuals and groups places some constraints on the concept that may not be compatible with certain views of equity or justice. The formulation by ~ ~ n andg Cole, however, provides a useful lens for analyzing quitea range of fairness issues. Test fairness as comparable validity implies a great deal for the ways in whichevidencecanbebrought to bear on fairnessquestions and challenges some olderways of thinking about fairness. Although popular discussionsoften speak of validity as itif were an all or nothing characteristic of a test, there is broad professional consensus that validityisneither a propertyof the instrument nor anall or nothing character is ti^. Inferences and actions based on test scores are validatednot the test itself-andvalidityisalways a matter of degree. The same could be said of fairness. X‘hinking of the concept as a matter of degree rather thananall-or-nonecharacteristic,however,maybeeven farther removed from common usage in the case of fairness that in the case of validity. It may also be more foreign to think of fairness as residing not in the test but in the inferences or decisions based on test scores. is especially port ant to Evidence about c o n s ~ c t - ~ r e ~ e vvariance ant an evaluation ofthe fairness of an assessment because groups may differ in a widevarietyofattitudes,experiences,andcapabihties that are not explicitly a part of the intended focus of meas~ement.The assessment wouldhavereducedvalidityandbelessfair to the degree that those ancillary skills and characteristics affect performance on the assessment. It shouldbe noted that s k i l l s that areconsideredancillary or sourcesof cons~ct- relevant variance for one inte~retationor use of assessment results may be relevant for part of the intent of meas~ementfor anqther inte~retation. The f i a l issue I want to mention before closing is an important one, but also a very complex and messy issue. That is the notion of opportunity to leam. Although it may be fair to include material students have not had

It is not correct to refer to the as avalid test of future graduate school performance, essentially because no test can be a valid test of sornething that has not yet happened. m e n we talk of its use as a prechctor, the more exact formulation would be to say that the GRI3 is avalid indicator of future graduate school performance (i.e., we can make vahd, although of course only probabilistic) inferences from the test to future performance. It is not a valid test of those matters, although it’s easy to see how we are tempted to talk that way. In medcal diagnostics, we have a number of tests for cancer. In the sense that we are using here, the biopsy is a logically valid test, because it hvolv &ectvisualidentification of cancercellsdirectlyremoved from nt’s body. The others-forexample, the ma sts of various states of affairs that provide from whch we can make inferences of modest to good valichty about the presence of cancer.(In the CronbachandMeehlterminology, h s isof course concurrent validity rather than the predxtive valichty of the GRE; for Messick,it’s‘diagnosticutility’anexcellentway to describeit.) One mightthink that at leastapositive m ~ r n o ~ aisalso m logicallyvalid because it is commonly thought to be an example of ‘seeing?the cancer; but the false positive rate is hgh just because benign m o r s present identically.

(The problem of oss sib le) ‘pseudoapplies to testsofteachercompetence that arebased on what experienced teachers say they see in the candidate’s performance.) Note that logcal s d a r i t y between test content and criterion is not the only relation that supports test validity; a mercury thermometer is a valid i n s ~ e n for t measuring temperature even though the volume of mercury is not a sample of the t h e ~ o d y ~ concept a ~ c of temperature. It is valid because it is calibrated so as to exactly exhibit an aspect of variations in erature-”and nothing else. When cows lie downin the fields, although S said to be an inchcator of corning rain,it is surely not an aspect of it. In general, there are no valid tests of future affairs, only indicators. Current states of affairs, however, are directly and validly accessible by tests ðe thermometer. Valichty in mathematics is &e validity in tests: it has to be supported by logically valid proofs. The judgment of good mathemati~ansas to the truth of u~provedhypotheses like Fermat’s Last Theorem is kghly correlated actual truth; but that does not make it proper to calltheir a type ofproof. So one should not call the reliability of inferences
Assessing Six Assumptions in Assessment ~5~ from results on test X to condition Y a kind of test validity; it's just a diagnostic inference,a shadow of corning events, not part of them. Although Messick wants to move to what he calls unified validrty, he takes this to include both of what are,I suggest, properly called validrtyand utility:
"he essence of unified validity is that the appropriateness, m e ~ ~ w e s s , and usewess of score-basedinferencesareinseparableandthatthe unifjmg force behind this integration is the trustworthiness of empirically grounded score interpretation, thatis, construct validity. (1989, p. 5) By contrast, although I alsowant to move to a unitary notion, it's a unitary notion ofvalidity only. I want to do thls by separating off the validity from theutdity. This meansabandoning all seriousefforts to identify separate notions of validrty"constmct valtdity, predictive validity, etc.-and r e c o ~ e n ~ that g weregardthemasmattersofuullty not validity, andthat we restrict the use of the concept of validity to the original and proper notion. We got seduced by talk of 'the nomological network' into r e ~ r all ~ legitimate g inferencesfromtestresultsaspartofthe valtdity of the test, instead of being a separate issue of inference validrty.(I was also seduced, which got my name in the attribution footnote to the original Cronbach and Meehl paper,so this can be seen as a slightly belated postscript to that essay.) A test is a valid test of X if and only if it directly tests for X, that is, it calls for performance correctly described as X or an essential part of X, whenadministeredandscored in theprescribed way to the prescribed population, etc. Predrctive or concurrent inferences are useful applications of a test, but not separate types of validity. Content and face validity are considerations in identifymg valid tests,but not separate types of validity in themselves. Constmct validity is an illicit combination of test validity and indicatorvalidity(i.e., the validityofinferencesfrom the test to other conclusions) So, a test of X that is useful in predicting Y should not be advertised as a test of Y' or even as a test forJI;it can be advertised as a testthat is a good indicator of Y, or as a test (that can be used) for predicting Y.

This became basedmodelofteacher e~aluation’andhasbeenwidelybuilt standardevaluationprocedures, often withstateendorsement. completely inappropriate procedure becausewe have-or can ready getevidence about criterial perfo~ance.This remindsusthatanyuse of indlcators (i.e., variables that justify an inferencein some cases) can only be justified when we cannot get or cannot afford to get criterial evidence (i.e., variables that defmethequalityweareseeking to identif));and this is indeed the case with the predictive use of academic tests. In the testing world, we tendto forget that teacher-made tes the largest proportion of tests in use. And validity as I have desc validity in the sense of what dlstant matters can be inferred from the results, isexactly the standardto whch theyshouldbeheld. In the worldof comrnercialtestin we aretodayfar more sensitive to lookingatthe consequencesofstingthanwewere,andatlooking at contextual modifiers: both of these r&d us that the long-chain inferences from test scores to futureperformanceare We shoulddemarcate the useof tests asprovidingdataforsuchcesfromthevalidityof the tests themselves,amuchmore robust propertyoftests. One should not be su~esting,as is too c o m o n today, that the validity ofa test is that fragile; we were wrong to tie validity to these weaker inferences, just as we were merit at all strongly to performance indicators, or hing styles. The validity of tests should be seen as s o m e ~ tied g logically,not correlatively, to the test. It is not a trivial matterto determine the validity of tes description of them, even in this narrower sense). The Test, for example, developed by an ETS te can’t be validated by just checking whether its items are all good of atical items. The desired label here-calling it “a test mathematic^ reasoning”-is not easy to attaim one must show that all ficant q e s of mathematical reasoning are covered, and that there is not too much emphasis on one rather than another. But that7s a feasible in the sloppysense(i.e., project,muchlessexpensivethanvalidation
validation of inferences to future performance). So, test validity is indeed a matter of whether the test tests what it says it tests, as the textbooks all say, but only if whatit says it tests is what it ~ i ~ tests. e ~ t ~
Naturally, the valichty of a test dependsnot only on its content, as we stated previously, but also on the way it is scored (and administered, etc., but we will here concentrate on the scoring). Considerationsoffairness,a c o ~ e n d a b l yfavorite topic of Sam Messiclr's and an important element in considerations, suggest that a requirement that I called the Point 9~ ~ ~ (PCR)i should ~ often ~ be e gven n center ~ stage in the chscussion of the test scoring component in validity. The PCR sirnply says that a point, however it is earned on the test, should represent an equal increment of merit on whatever it is the test is said to be a test of. We'll never attain this ideal in practice, but we can certainly get reasonably close to it: the paradigm is a test of basic arithmetic skill. It should be treated as an ideal in the design of all scoring keys (a.k.a. rubrics). Moreover, it is an ideal that should be a p p r o ~ a t e d not , treated as extremely remote. (For convenience,wecanfocus on quantitativescoring, a l t h o ~ gthe ~ same principle extends to qualitative assessment, e.g., most gradmg.) Note that the PCR does not involve c l h s about item (-success) difficulty, only itemsuccess merit. The two are connected, of course,but it's easier to all basic two-by-two multiplication items are of equal merit, in of arithmetic competence, thanthat they are of equal difficulty; andone can do it from one's armchair, which helps the development budget The PCR is a principle that governs test valichty, but its ethical aspect surfaces when we look at the continuing failure of students in less-wellfunded schools to receive any training in test-tahg SUS. This means, for example, on the usual multiple-choice tests, that they are not taught to: (a) put in answers by guessing, when theydon't h o w or have time to work out the correct answer; and (b)answer the easy questions fust. Imechately, we have adverse impact: and, for SM and MS as well as all the enthusiasts for consequential validity, we have test invalidity. Not because of the adverse impact, however, although that must be studied, as SM stressed, because it often serves to warn us of invalidity,but because the test is in fact a test of two quite different skills, although its results are being treated as if the test only tested oneofthese skills. Students from the wealthierdistricts or parents are getting extra scoreson that skill by virtue of having ~urchased)
Assessing Six Assumptions in Assessment 2 the other skill; a clear violation of the PCR.“he worst violation of the PC er, involves a more general problem, mentioned as item (a) above. guessing on the usual multiple choice test has an expectancy of 25% and a merit of zero, a flagrant violation of the PCR.

Hence, in case you were getting a little sleepy by now, it is provable that all standard multiple-choicetestsareinvalid.I’lllaterindtcate how to correctthis without plungmg off the straight and narrow path ofsound testing into the do-authentic testing. argument for this conclusion concerns item (b)above; the ingle point for all correct answers, when in fact a correct answermaybemuchmoremeritorious onone ratherthan another question. I’ll now extend our list to include a third breach of the PCR. ”hls is (c) the failure to distinguish between the score for incorrect answers (i.e., zero), when in fact,on some items (not all) some incorrect answers are very as correct as the officialcorrectanswer,whereas other distractors would only be chosen by someone with essentiallyno knowledge of the topic. (Note that there are test items, e.g., in competency testing for surgical or airline pilot skills, in which one wants to say that any answer besides the correct one is equally and absolutely valueless;but these are the exception rather than the rule.) In terns of our list of assumptions for assessment, under the headtng of testscoring weare now addressingthree common a s s ~ p ~ o nofs standardizedtesting(twoofthemare not entirelyindependent): the assumption that blind gues can legitimately yield 250/0(in the usual case; 20% in some other cases); a s s ~ p t i o nthat all correct responses should be equally weighted in the scoring key; and the assumption that allincorrect responses should be equally weighted. These d bring us up to a total of lihave dtscussed. four assumptions that we w I w i l l propose relatively easy fixes for each of these problems; the main ~ n c t i o n sof theproposalsare to that fues are not impossible,and to stimulatediscussion,ratherthanttheseare the only or best ways to fix the problems. But &st I need to head off the usual dismissal of any Lord, for they attempts to fix them. It is commonly said-forgive them, h o w not what they do“--that such changes have been shown repeatedly to have little effect on the rank ordering of testees. Justice is not done by

But there is also actical issue. To t h s enlightened company of colleagues, I am sure I need not stress that the days of ~~g that tests are to be rated purely or even mainly as i n s ~ e n t for s d i s c ~ a t i n g(rank-order in^ are over. We are interested in criterion-referenced testing as well as norm-referenced, not always but often. We need the total score on a test to be an indication of competency, not just of relative c o m ~ e t e n This ~ . has some S consequences(e.g., that we need to avoid the old practice of v ~ d a t i o nin which we threw out items that did not correlate well with other items, without thorough exploration of the possibility that they were probes into untouchedregions of the domain). (m the critical thinking area, r exaxnple, they often werejust that.) In the presentcase, we want a score at represents the actual value of the testee’s knowledge or skills as well as is practicable. So we must set up the scoring key to measure that knowledge asaccuratelyas we can,asalways with due respect tocost feasibility. g wdl always follow from gradmg, but should not be the p h q Cnction of most tests, and ~ s c ~ a t i power o n should not be the key index o f merit in items. The crucial question about a c~terion-referenced test, analogous to the question of how many testees are wrongly ranked, ,“How accurateand how efficient is our estimate of total ge?” Some rough calculations suggest a surprising figure. In round numbers, our presentscoring system oftenthrows away 50% of the i n f o ~ a t i o nthat is on the answer sheet turned in by the testee. We can recover most of that extra i n f o ~ a t i o nby adding estimates of variable item merit, variable error merit, and by scoring the test so as to elininate any expectancy for guessing. h e s for t h s wastage that I a m going to suggest involve three fairly S procedures,but no pretense ismade that they donotinvolve any extra costs.

On our account, the situation is much simpler: the test is valid onlyifitsscoresmatchitstitle. It may beusefulforcertainpurposes without meeting that requirement; but that match is what is required for validsty. It is likely to be more useful, for criterion referenced evaluation, if we make the scoring more defensible. ea^-^^^^ Scomirg. In general terns, therearetwo ways to produce improvedtests that takesomeofthesesuggestions into account:test conversionandtestcreation. The furst meansimproving the scoring of tests;thesecondmeansimprovingthe instrument itself in the course of creating it. Item weighting is easily usedin conversion; near-miss weighting can be used either way. In the conversion scenario, using the existing distractors, inspection w i l l usually reveal that some of them are only subtly different from the correct answer, whereas others wouldonlybe chosen by someone who was extremely conhsed about the subject or knew little or nothing about it and was essentially guessing. The is that in many cases it is more appropriateto reward the tes thedifferencebetweennearlythebest option and the awarding half a point for the near-miss. From the diagnostic point of view there is obviously considerable value in knowing this, in order to adjust future teaching: more on this in a moment. In the construction scenario, eer the items so that they illustrate this distinction more clearly since it is animportant distinction. An independent reasonformakingtheseeffortsis that they all contribute to improved ~ c ~ - which v a leads ~ ~ to ~ much ~ improveduser relations,aswehavediscoveredinevaluatingtestsinthepersonnel evaluation field. The changes described do something to avoid the many complaints about what is often described as the ‘‘rigid” and ~‘unfor~ving’’ nature of standard multiple-choice tests. At this point, we need to say something more about the diagnostic use of these reweighted items. By running a computer analysis that identifies the number of near-misses in the score total versus the number of “farrnisses”versusthenumberofcorrectoptionschosen;andbetween the number of points scored on single-weighted items by contrast with those weighted 50% and 100% more, wecan often identifya pattern that is
Assessing Six. Assumptions in Assessment 267 helpful for instruc~onalpurposes. For example, we might be ableto suggest that an inordmate number of responses are in the near-miss category and that the testee needs to focus more on getting exactly the right form of expression or the right qualifications into their understanding of a matter. Or we might be able to classify someone as doing very well on basic items (merit level = weight = l) by contrast with those worth double the points. to identifythe f ~ g e r p of ~ tthe (lwgely) random We should also ble isdoingratherbetterthantheexpectancy for that approach. When in the construction mode,it d also be desirableto try to restwict the actual range of item difficultyto the range we are recowzing with our 200% spread (i.e., to avoid items that are much more than twice as hard or meaty than any other item). This d improve the absolute accuracy ofour scoring as an e s h a t e of merit(andtheaccuracyof our e s h a t e of i n f o ~ a t i o ngained over the standard approach), although thes~periorityof near-miss scoring over the standard method of level scoring will not be slightest. Ethically, as well as impaired, or improved, in the epistemolo~c~y, the advantage of doing this is to reduce the payoff from the testwise strategy of doing easy items fwst. (Of course, there will s d be an advantage in doing items fast that are easy for you.)
~~~-~~~~$co~&g. Now we come to the feature ofour scoring reform plan that eliminates pay-for-~essing.Let’s begin with a plan we won’t stay with but which indicates the approach. Supposewe are convertingor creating an item with four options, one correct, one near-miss, one plain wrong answer withoutredeemingfeatures(but not ridiculous),and one far-miss(i.e., hopelessly wrong/absurd answer). If this is a typical item, and if we score one for the correct answer (subject to the multiplier from the weighting of the item), half for the near-miss, zero for the plainly wrong answer, and minus 1.5 for the absurd answer absu sur^' only if you understand the field), the expectancy from blind guessing goes to zero, and with it the benefits of testwise ~ ~ i innthisg respect. Or you could deal with an item that had two far-missanswersbyscoringtheresponses 1, .5, -.75, -.75, withthe same net effect. And so on for near-misses.The possibfity of a net negative score on some items creates the possibility that the testee loses points that were l e ~ h a t e l ygained on other items. At fast sight this seems “unfair“; however, it is only the total score thatis used for test-dependent actions,or that is relevant to test validity, and the total score more accurately reflects me& if thisconstraintisimposedonit.

My career has been strongly influenced by various mentors, but strangely withmuchdelayfromthe h e atwhichtheirinfluencewas fist encountered.Perhapsthe delaywasmywayofindicatingintellectual independence, not to adopt the approaches of my mentors while I was still in their presence. m e n I worked with Elliot Aronson at Hmard, I stayed away from his favored coptive dissonancetheory, but started wY.iting articles on the topic 15 years later. Gordon Allport advised my work on a dissertationproblem that I devised to bequiteremotefromhistopic interests and preferred research methods. Fifteen years later, however, I was working on one of his favorite topics, the self, and after nearly another 15 years I was working on prejudice, another of Allport's major topics. It is therefore no surprise to me to recognizethat,manyyearsafterbeing exposed to SamMessick during a fewformativepostdoctoralyearsat Educational Testing Service,I developed a research progrm that combines three of his career-long passions, psychological testing, construct validity, and educational psychology. How these influences worked themselves out in my research of the past several years, ina fashion that I hope d please Sam,is what this chapter is about. The psychologicaltest in whichbecame I interestedis a set of ~ n ~t i ~ ~ t ~Anyone c t i o n who . teaches at a procedures known as ~ t ~rating university in the United States has been exposed to these, as have those who teach in many other countries. In 1989 and 1990 I received widely divergent ratings for teaching the same course in 2 successive years, using the same syllabus, text, course requirements, meeting format, etc. Althou the discrepancy could conceivably have been nothing other than sampling error, it was impressive in degree"-my average ratings were separated by 8 277
deciles(about2.5standarddeviations) on theuniversity norms that accompanied the ratings reports I received. Searching for an e~planation,I natura~ysuspected that the ratings were influenced by something other thanthequalitiesoftheinstructor, whch shouldhavebeenalmost as as possible over the two offerings of this particular course. Perhaps s i ~ ~ c athat n t I fEst approached &.IS topic as an outsider who had previous research involvement in the topic. My first research on the ic therefore had some of the character of the naivechildseeing the Emperor’s New Clothes.

Fortunately,this d i s c ~ a n validity t problem of therawunemploymentratedoes not render those data useless. Ifone applies appropriate adjustments for known seasonal effects, then the adjusted unemployment rate can provide a valid measure of the overall economy. Student ratings measures are now used in most undergraduate institutions without any adjustments. In other words, student ratings are treated asiftheyhaveexcellentdiscriminantvalidtty. It is assumed that student ratings do not suffer from any substantial c o n t ~ a t i n influences g (as asserted, e.g., in the previously quoted remark byMcKeachie,1979).

For a reason soon to be made known, I had occasion to fly from C ~ f o to~ the a east coast during those tense days, a trip made with some trepidation I must say, and one whose attendant feehgs I stdl vividly recall.

As new acquaintances Sam and I hit it off fromthe start. We found that we had a lot in common, both professionally and non-professionally. On the professionalside,wewere both interested in problemsof psycholo~ca~ assessment, particularly the assessment of creativity.I had just co-authored a ~ n ~ ~ ~ ~ ~e Z ~~ ~Z e onwith c ~~G@ed :~ ~ ~ o book withJ.

We also tried to give some order to the qualities we identified. We did so by positing a developmental h yet-to-be-tested components of the construct of our work involved us in what might properly becalled the ~tmctzr of the construct ofcreativity.Another way of at we wereabout w d be introduced later. our work onthe paper my o m enthusiasm for c o n t i n ~ to g doresearch on creativity suffered a serious setback. It did so as a result ofthe trip to the east coastthat I have already mentioned. "he reason for my trip and what I found when I got there are both a bit complicated, so I must explain eachin some detd. In the research described in our book Getzels and I had focused on two groups of students identified from among all of the students, from the sixth ade forward,then attending the ~ ~ v e rofs Chicago's i ~ Laboratory School. had p e r f o ~ e very d wellon several tests of creativity, so-called, but so o u t s t a n ~ g l yon a standard test ofintekgence; the other group had apattern of scores exactlythe reverse. We sought to compare those two groups on a wide variety of dependent variables having chiefly to dowith their ~ e r f o ~ a n c in e s school-variablesliketeacher and peer ratings, attitudes toward school and f a d y , career asp~ations,and so forth. The five tests comprising our ''creativity" battery had either been modeled or after were exact of investigations of creativity copies of tests employed in a wide variety other J.P. Gdford, Raymond B. Cattell, E. Paul ors such as on. Here is how we describedthat set of five tests.
In general, our tests of creativity involved theability to deal inventivelywith verbal and n ~ e r i c a symbol l systems and with object-space relations. m a t most of these tests hadin cormnon was that thescore depended not on a single p r e d e t e ~ e dcorrect response ..but on the n w b e r , novelty, and varietyof adaptive response to a given s ~ task.

I also reasoned that the students themselves were probably not s u f f e ~ &om g having been so identified and might even be benefitting from their new educationala~angement.In.the end, my curiosity turned out tobe g s stronger than my sense of disapproval. So I suppressed my m i s ~ ~ and accepted the supe~tendent’sinvitation. I looked forwardto what my journey to Easton heldin store. My visit there covered three school days plus a day of traveling at each end. I spent mostof the timetheresitting in the backof the expe classroom, watchmg the tom’s 25 %nost creative” sixth graders and their “most creative” teacher goabout their business. m a t I saw turned out to be interesti~g,all right,but not at allin the way I had anticipated. During my first m o ~ n g ’ svisit I waschieflystruckbyhow e v e r y ~ looked. g The physical classroom, the students, the teacher, looked pretty much like their counterparts back in the Laboratory School in Chlcago, which, inturn, had looked to me pretty much &e the classrooms I had inhabited as child, I had no particular expectations about what I would witness in Easton but somehow I expected it tobe hfferent from whatit was. “he room was bright and cheerful with plenty of colorfid charts and samples of student artworkondisplay. The students seemedeager to participate in whateveractivity the teacher introduced. “hey raisedtheirhandswhen questioned. They huddled together in smallgroups to work on projects of one h d or another. They read silently during free reading time. They wrote reports. They moved about the room andchatted comfortably with each other and with their teacher during study periods. Andso on. The cwriculwn too contained nothing out of the ordinary that I could see; justthe standard school subjects of math, social studies, language arts, science, and so forth. Long before my first fullday of observation had ended I found myself sti and beginningto wonder whetheror not the trip would turn out t worthwhde. Some questions pertaining to construct validity did enter my thinkmg h o s t at once onmy first day. I worried first of allabout how well the testing had been handled.

(More on that too in due course.) But my new tourist-like gawking seemed &e the right thing to be doing and elementary classrooms seemed like the right place to do it. I m fast a p p r o a c ~ gthe end ofmy two anecdotal accountsbut I cannot resist adding a brief extension to the story I have just told. It ties to one of the things I later want to say about construct validity. In retrospect, I find it musing, although I dld not find it so at the time. N.L. Gage had just moved from the University of Illinois to Stanford that year. As we were both newcomers to the west coast and had known each other casually before then, we decided to get together on a fairly regular basis to compare notes on our new surroundings and to share some of our conxnon interests. At one of our lunchtime meetings shortly after my return from Easton I announced to Nate my planto visit some local classrooms just to look around and see whatwas going on.He stared at meas if 1had lostmy mind. ‘TI0you know what you’re doing, Phil?,”he asked incredulously, ‘You’re the electriclight!’’ What he meant, of course, s t u d ~ the g oil lamp in the of age was that any teaching I might observe was soonto be outdated and replaced by an entirely new mode of instruction that would be based on “scientific” research. He and his students at Stanford were then busily engaged in exactly the kind of research that they confidently believed would one day form the basis ofa new science of teaching. Numerous others were sknilarly engaged at u~versitiesaround the country and throughout the world. Although Nate did not come right out and say so at the b e , I have no doubt that he also believed that what I was proposing to do was unworthy of being called “research,” much less ‘cscience.’’ He might then have conceded (as he later did in someh ~ofwritings) s that the kmd of unstructured observations that I was about to undertake could possibly leadto science. “hey might, in other words, become the source of hypotheses that could later be tested but this meant that they were no more than exploratory in nature, somethingto engage in very briefly before getting down to brass tacks, which isto say: the serious business of doing research.“he latter, as both Gage and I at the time if asked, entailed undertaking a carefdly designed would have readily explained study, ~ a t h e ~ quantifiable g data,analyzing it statistically,presentingits S in tabular or graphic form, andso on. confess that at the h e Gage’s reaction aroused worries that even then I had worked hard had not been very far beneath the surface of my thoughts. how to design and conduct empirical studies. I was moderately pleased with whatI had already managed to accomplish alongthose lines.I was
Construct Validity and the Language 30'7 also as confident as was Gagethat Science with a capital S offered the only true a psychologist, particularly route to knowledge. I further took pride in being one who did research,The prospect of givingup that identification was not at allattractive, in fact it made me very uneasy, yet that was the dkection whchin my proposed plan pointed,as Gage's reaction to it clearly implied. d I have something h t h e r to say about the source of my uneasiness in due course. I now want to turn from my two anecdotal accounts to a set of remarks about construct validity as a tool of thought. All that has been to this saidpoint w li continue to reverberate as background? I trust, as I move on to what follows. My concerns are twofold. They have to do in part with what might be called the ontological status of constructs, with what thec word o ~ stands ~ ~ for ~ and c ~ with howwe habitually speak of whatever the term represents. "hey also have to do with the validation process qua process and with whether and why we should insist onit being perceived as scientific.
Do psychological constructs like intelligenceor anxiety or creativity refer to red? entities that truly exist or are they fictional devices, more theoretical than The answer to that question,according to philosopherStephen Norris, dependson one'sphilosophicalpedigree (Norris, 1983). "hose who call themselves logical positivists, for example, (a dying breed, it would seem) answer in one way, whereas those who think of themselves as realrsts (a term of self-reference alsonot in wide use, it again would seem) answer in another."he former treat constructsas fictions and thereby tend to dismiss them; the latter see them as real and thereby attach great importanceto them. VVhich one is correct? The issue, according to NOIT~S'S account, remains open to debate, although not as tendentiouslyperhapsaswasoncethecase.Moreover, opposing views of the matter are by no means limlted to philosophers who attach themselves to one or another school of thought. They also include, among others: psychologists, educational researchers, and test-makers. It is among the latter, Norris tells us, that we find some of the most ous forms of ignorance and confusion with respect to this important set of questions. The chief dtfficulty, we are told, lies in the inconsistency with which test-makers in particular view and discuss the ontological status of psychological constructs. Sometknes they treat them one way (as real) and sometimes another (as fictional). Some, it would seem, want to have it both ways at once. Still others appear not to care very much one wayor the other

When it comes to establishing fiuitfid waysof thinking about particular constructs, even when one of them posits something real and other the does not, the law of the excluded middle,it would seem, neednot always apply.

His worry, we d recall, was t ultimately suffer the negative effects of such inconsistencies.

Moreover, the risks involved in different ways of speaking are commonly m u l ~ p l i by e ~the a u t h o r i ~of the speaker.Those who present themselves as experts and who speak in the n m e of science or research do so fiom positions of authority that elevate the significance of their words far above that of the or&ary speaker.

Dewey went onto urge teachers (and others)to dunk of intelligenceas being more like an adjective or adverb than a noun, By so doing, he believed, teachers in particular would be more inched than they otherwise might be to ask how persons may be encouraged to behave moreinte~gentlyin particular circ~stancesand with referenceto particular lrlnds of materials and subject matter. In making those suggestions, Deweywas not advocating that teachers be so to speak, about well-established facts having to do with the kept in the dark, relative stability of performances on intelligence tests or a n w n g else of that nature. He was., however,q u e s t i o ~ the g wisdom of certain practices, such as s u p p l ~ gteacherswitheachstudent’sscore on suchatest. He also by i n ~ e c t i o nwas c a h g into question the kind of talk about intelligence that causal potency than the facts allow. Wedo not have to s h a t e of the risks involved in such practices and such talk to understandwhathethoughtthose risks to be. He fearedthat misinformation and even accurate ~ f o ~ a t i oirnproperly n7 co~unicated, might inadvertently contributeto a decline in teachers’ effortsto do the best they can for each of their students. The possibdity of untoward consequences being associated with certain ways of talhng about psychological constructs callsto rnkd Messiclr‘s many discussions of what he calls c the o~se~~ basis e nof~ validity, ~ ~ Z which refers to the social c o n s e ~ ~of e ~test c e ~use and interpretation (Messick, 1989a., 1989b., 1995). Would Dewey’s worries about how teachers might make use of the construct of intelligencefit comfortably within Messick‘s category of s o ~ ~ Z c O ~ s e ~ ~ Ie ~ c e s ? see no reason why not. Indeed, they seem to me to provide an almost classic instance of the kind of concerns with which today’s eahtened test-m~ers are increasingly occupied. FollowingDewey’slogic,might it bethat,ingeneral,adjectivaland adverbial ways of referencing psychological constructs are better suited to the within educational contexts than are the more kinds of discussions that go on noun-referenced discussions that typify so many psychology textbooks?

314 Jackson As part of their effort to make test use and interpretation scientifically respectable, Cronbach and Meehl includedwithin their paper (in a section subtitled “The Logicof Test Use”) alot of talk about “theinterlocking systemof laws which constitute a theory as a ~ o ~ o Z o ~g ~ e~ ~~Z (Cronbach ~ o ~ & ~:Meehl, ’ 1955, p. 290).

Things &d notturn out quite asCronbach and Meehl hadhoped. Not only were not all of the t o u g h - ~ d e dreassured by the article’s appeal to the criterion of scientific methodology, but, ironically, at least one such tough~ d e critic, d HacoldBechtoldt of the Universityof Iowa, was quickto accuse the article’s authors of themselves beingnonscienti~c.Bechtoldt mote: The renamingof the process of building a theoryof behavior by the new term‘constructvalidity’contributesnothingtotheunderstanding of the process nor to theusefidness of theconcepts.Theintroductioninto discussions of psychological theorizing of the aspects of construct validity [discussed in this article] ...creates, at best, unnecessary confusion and, at worst,anonempirical,nonscientificapproachtothestudy of behavior. (Bechtoldt, 1959, p. 628) The vituperative toneof Bechtoldt’s accusation is indicative of the passions that could be easily aroused in those days by any perceived threat to the scientific status of psychology. L o o h g back on lus jointly written paper some 30 years later, Cronbach sounded apologetic and almost embarrassed byits scientistic flavor, He said, Paragraphs on the network andon links between theoretical notions and d to the CM [Cronbach & Meehl] paper.

Cronbach’scandorisunsparingandexemplary.“Adding “‘bolstering a virtuous claim,)’ being “pretentious,” and “self-defea behalf of an ‘‘in~rnature science”-those are harsh things to say about one’s prior behavior, even from the distance of several decades. Yet, although applauding hisf o r ~ g h ~ e swe s ,must not ignore the question of why he and Meehl might have behaved that way in the fixst place. A piece of the answer surely must in liethe aspirationto be tough-minded and to be seen as being so, which, at least back then, translated into the goal of beingscientificandofscience.Moreover,thatPast, to somedegree, remains our Present. No psychologist, then or now, can remain completely indifferent to such aspirations. To do so would cast doubt on lus or her entitlement to membership within the community of psychologists. It was certainlythe fear ofthat happening that made me wary back in 1962 when 1 turned &om p i n g paper-and-penc~ tests to more informal and naturalistic methods of data- the ring. Was I not giving up science in the process? That was the question I asked myself at the time, I feared I was, knew that not every psychologist crunched nwbers and worked data. In my heart of hearts, however, I harbored little respect for those psychologistswho had nothing but words at their command. That lack of respect was widely shared by the majority of the faculty and students with whom Istudled, I must say,andremainedevidentamongmycolle associates at Chicago and elsewhere. In his 1989 overview of the history of construct validity, Cronbach clearly rues the pretensions associated with his earlier effort to pacify the toughminded andto keep psychology scientifically respectable. Yet if one reads his 1989 papercaremy one canstill discern, I believe, traces of the attitudes and biases that partially motivated the earlier work. In 1989 he stdl spoke h o s t w i s t ~ yof “‘the community of pure scienti~ts’~ and of “the very lon enterprise of pure science” which lives “for daythe whentruth becomes crystal clear’7 @. 163).
