Personality scale validities increase throughout medical school.

Admissions and personnel decisions rely on stable predictor–criterion relationships. The authors studied the validity of Big Five personality factors and their facets for predicting academic performance in medical school across multiple years, investigating whether criterion-related validities change over time. In this longitudinal investigation, an entire European country’s 1997 cohort of medical students was studied throughout their medical school career (Year 1, N = 627; Year 7, N = 306). Over time, extraversion, openness, and conscientiousness factor and facet scale scores showed increases in operational validity for predicting grade point averages. Although there may not be any advantages to being open and extraverted for early academic performance, these traits gain importance for later academic performance when applied practice increasingly plays a part in the curriculum. Conscientiousness, perhaps more than any other personality trait, appears to be an increasing asset for medical students: Operational validities of conscientiousness increased from .18 to .45. In assessing the utility of personality measures, relying on early criteria might underestimate the predictive value of personality variables. Implications for personality measures to predict work performance are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Big Five factors of personality and replicated predictions of behavior.

Measures of the Big Five factors of personality were used to predict a variety of criterion variables thought to represent behaviors of some social and cultural significance (e.g., alcohol consumption, grade point average). Analyses focused on replicated predictions across 2 independent samples of participants (Ns=276 and 142) with 3 different measures of the Big Five (the NEO Five-Factor Inventory, the Revised NEO Personality Inventory, and the Five-Factor Nonverbal Personality Questionnaire, the latter an experimental nonverbal personality inventory). The results indicated substantial consistency in behavior predictions across the different Big Five assessments. The data are interpreted as supporting both the construct validity of the personality measures used and the role of the Big Five factors as determinants of certain complex behaviors.

The Proactive Personality Scale and objective job performance among real estate agents.

A sample of 131 real estate agents was used to examine the criterion validity of the Proactive Personality Scale (T. S. Bateman & J. M. Crant, 1993). A job performance index was computed for each agent from archival records of the number of houses sold, number of listings obtained, and commission income over a 9-month period. Experience, social desirability, general mental ability, and 2 of the Big Five factors—Conscientiousness and Extraversion—were controlled for, and the Proactive Personality Scale explained an additional 8% of the variance in the objective measure of agents' job performance. These results provide additional evidence for the criterion validity of the Proactive Personality Scale and suggest that specific personality measures can have incremental validity over the Big Five factors.

Benchmarks: Integrating affective and interpersonal circles with the Big-Five personality factors.

Previous research on the Big Five personality factors has not accounted for trait variables interstitial to the factor poles. To better integrate interstitial variables with the Big Five and to provide a framework for reconciling variant versions of the 5 factors, 636 self- and peer ratings using a set of 394 trait adjectives were analyzed. Pairings of 3 factors (I, II, and IV) showed a markedly large incidence of interstitial variables. These 3 factors, referencing affective and interpersonal traits, formed a 3-dimensional space. Adjective clusters defining both factor-univocal and interstitial benchmark positions in this space were developed. The 3 circles defined by the clusters showed appropriate circumplex characteristics when examined in an independent sample of 205 peer ratings. Two of these circles corresponded to the affective and interpersonal circles defined by personality research. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The Mini-IPIP Scales: Tiny-yet-effective measures of the Big Five Factors of Personality.

The Mini-IPIP, a 20-item short form of the 50-item International Personality Item Pool-Five-Factor Model measure (Goldberg, 1999), was developed and validated across five studies. The Mini-IPIP scales, with four items per Big Five trait, had consistent and acceptable internal consistencies across five studies (= at or well above .60), similar coverage of facets as other broad Big Five measures (Study 2), and test-retest correlations that were quite similar to the parent measure across intervals of a few weeks (Study 4) and several months (Study 5). Moreover, the Mini-IPIP scales showed a comparable pattern of convergent, discriminant, and criterion-related validity (Studies 2-5) with other Big Five measures. Collectively, these results indicate that the Mini-IPIP is a psychometrically acceptable and practically useful short measure of the Big Five factors of personality.

What is being assessed and why it matters: The impact of transient error on trait research.

Temporal instability can reflect either true psychological change or transient measurement error, and it is important that trait psychologists be able to distinguish one from the other. The authors report results from large retest studies of Big Five, trait affectivity, and personality disorder measures across time frames (2 months and 2 weeks) over which these constructs should show little or no true change. On average, nearly 25% of the variance in the measures was a product of transient error rather than true change; however, the proportion of error varied widely—but consistently—across measures. In addition, a reexamination of long-term longitudinal data demonstrated that ignoring transient error can lead to inaccurate conclusions. Most notably, a substantial portion of the observed instability in the Big Five and trait affectivity is due to transient error; thus, these traits are even more stable than commonly thought. The present data further suggest that previous reports of differential stability between the Big Five and trait affectivity are due, in part, to differential levels of transient error in measures of these constructs.

The nature and structure of correlations among Big Five ratings: The halo-alpha-beta model.

In light of consistently observed correlations among Big Five ratings, the authors developed and tested a model that combined E. L. Thorndike’s (1920) general evaluative bias (halo) model and J. M. Digman’s (1997) higher order personality factors (alpha and beta) model. With 4 multitrait–multimethod analyses, Study 1 revealed moderate convergent validity for alpha and beta across raters, whereas halo was mainly a unique factor for each rater. In Study 2, the authors showed that the halo factor was highly correlated with a validated measure of evaluative biases in self-ratings. Study 3 showed that halo is more strongly correlated with self-ratings of self-esteem than self-ratings of the Big Five, which suggests that halo is not a mere rating bias but actually reflects overly positive self-evaluations. Finally, Study 4 demonstrated that the halo bias in Big Five ratings is stable over short retest intervals. Taken together, the results suggest that the halo-alpa-beta model integrates the main findings in structural analyses of Big Five correlations. Accordingly, halo bias in self-ratings is a reliable and stable bias in individuals’ perceptions of their own attributes. Implications of the present findings for the assessment of Big Five personality traits in monomethod studies are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Higher-order factors of the Big Five

Estimated factor correlations from 14 studies supporting the 5 factor, Big Five model of personality trait organization--5 studies based on children and adolescents, 9 on adults--were factor analyzed. Two higher-order factors were clearly evident in all studies. One was principally related to the Big Five trait dimensions Agreeableness, Conscientiousness, and Emotional Stability; the other, the dimensions Extraversion and Intellect. Two models, one for children and adolescents, the other for adults, were tested by confirmatory factor analysis with generally excellent results. Many personality theorists appear to have considered one or both of these 2 metatraits, provisionally labeled alpha and beta.     

Personality and cognitive ability predictors of performance in graduate business school.

A cross-validation study is reported in which both personality variables and cognitive ability variables were evaluated as predictors of 2 separate performance criteria in a sample of 450 Master of Business Administration students. Whereas verbal and quantitative aptitudes of the students were found to be strong predictors of performance at written work, they were weak predictors of an in-class performance criterion. The opposite was true when specific personality trait variables were used as predictors. The personality characteristics of the students predicted classroom performance better than they predicted written performance. The Big Five factors of personality (Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness to Experience) did not predict either criterion consistently. In conclusion, personality variables are related to academic success when characteristic modes of behavior play a role in academic performance.

Integration of the Big Five and circumplex approaches to trait structure.

To integrate the 5-dimensional simple-structure and circumplex models of personality, the Abridged Big Five Dimensional Circumplex (AB5C) taxonomy of personality traits was developed, consisting of the 10 circumplexes that can be formed by pitting each of the Big Five factors against one another. The model maps facets of the Big Five dimensions as blends of 2 factors. An application to data consisting of 636 self-ratings and peer ratings on 540 personality trait adjectives yielded 34 well-defined facets out of a possible 45. The AB5C solution is compared with simple-structure and lower dimensional circumplex solutions, and its integrative and corrective potential are discussed, as well as its limitations.

On the temporal stability of personality: Evidence for differential stability and the role of life experiences.

The authors investigated the stability of personality and trait affect in young adults. In Studies 1 and 2, young adults were retested on a Big Five personality measure and a trait affect inventory over a 2.5-year and a 2-month period, respectively. Results from Study 1 point to positive mean-level changes; participants scored higher on Extraversion, Openness, Agreeableness, and Conscientiousness at Time 2. Affectively, participants experienced less negative affect and more positive affect at Time 2. Results from both retests provide clear evidence of differential stability. Affective traits were consistently less stable than the Big Five. Other analyses suggest that life events influence the stability of affective traits more than the Big Five.

Relationship of personality to performance motivation: A meta-analytic review.

This article provides a meta-analysis of the relationship between the 5-factor model of personality and 3 central theories of performance motivation (goal-setting, expectancy, and self-efficacy motivation). The quantitative review includes 150 correlations from 65 studies. Traits were organized according to the 5-factor model of personality. Results indicated that Neuroticism (average validity=-.31) and Conscientiousness (average validity=.24) were the strongest and most consistent correlates of performance motivation across the 3 theoretical perspectives. Results further indicated that the validity of 3 of the Big Five traits--Neuroticism, Extraversion, and Conscientiousness--generalized across studies. As a set, the Big 5 traits had an average multiple correlation of .49 with the motivational criteria, suggesting that the Big 5 traits are an important source of performance motivation.

Predicting actual behavior from the explicit and implicit self-concept of personality.

The authors present a behavioral process model of personality that specifies explicit and implicit aspects of the self-concept of personality as predictors of actual behavior. An extensive behavioral study (N = 130) including a variety of relevant social situations was conducted. This approach allowed reliable measurement of more than 50 behavioral indicators. A priori assignment of indicators to the Big Five dimensions was conducted on the basis of theory and expert ratings. In line with the authors’ model, 3 main findings were revealed: First, direct measures (questionnaires) of personality predicted actual behavior for all Big Five dimensions. Second, indirect measures (implicit association tests) of neuroticism and extraversion also predicted actual behavior. Third, the predictive validity of these indirect measures was incremental. The authors were additionally able to show that controlling for valence did not affect any of these results. Implications and future prospects for the study of personality and actual behavior are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Los Cinco Grandes across cultures and ethnic groups: Multitrait-multimethod analyses of the Big Five in Spanish and English.

Spanish-language measures of the Big Five personality dimensions are needed for research on Hispanic minority populations. Three studies were conducted to evaluate a Spanish version of the Big Five Inventory (BFI) (0. R John et al., 1991) and explore the generalizability of the Big Five factor structure in Latin cultural groups. In Study 1, a cross-cultural design was used to compare the Spanish and English BFI in college students from Spain and the United States, to assess factor congruence across languages, and to test convergence with indigenous Spanish Big Five markers. In Study 2, a bilingual design was used to compare the Spanish and English BFI in a college-educated sample of bilingual Hispanics and to test convergent and discriminant validity across the two languages as well as with the NEO Five Factor Inventory in both English and Spanish. Study 3 replicated the BFI findings from Study 2 in a working-class Hispanic bilingual sample. Results show that (a) the Spanish BFI may serve as an efficient, reliable, and factorially valid measure of the Big Five for research on Spanish-speaking individuals and (b) there is little evidence for substantial cultural differences in personality structure at the broad level of abstraction represented by the Big Five dimensions.

Replicability and 40-year predictive power of childhood ARC types.

We examined 3 questions surrounding the undercontrolled, overcontrolled, and resilient—or Asendorpf–Robins–Caspi (ARC)—personality types originally identified by Block (1971). In analyses of the teacher personality assessments of over 2,000 children in 1st through 6th grade in 1959–1967 and follow-up data on general and cardiovascular health outcomes in over 1,100 adults recontacted 40 years later, we found bootstrapped internal replication clustering suggesting that Big Five scores were best characterized by a tripartite cluster structure corresponding to the ARC types. This cluster structure was fuzzy rather than discrete, indicating that ARC constructs are best represented as gradients of similarity to 3 prototype Big Five profiles; ARC types and degrees of ARC prototypicality showed associations with multiple health outcomes 40 years later. ARC constructs were more parsimonious but, depending on the outcome, comparable or slightly worse classifiers than the dimensional Big Five traits. Forty-year incident cases of heart disease could be correctly identified with 67% accuracy by childhood personality information alone and stroke incidence with over 70% accuracy. Findings support the theoretical validity of ARC constructs, their treatment as continua of prototypicality rather than discrete categories, and the need for further understanding the robust predictive power of childhood personality for midlife health.

An other perspective on personality: Meta-analytic integration of observers' accuracy and predictive validity.

The bulk of personality research has been built from self-report measures of personality. However, collecting personality ratings from other-raters, such as family, friends, and even strangers, is a dramatically underutilized method that allows better explanation and prediction of personality's role in many domains of psychology. Drawing hypotheses from D. C. Funder's (1995) realistic accuracy model about trait and information moderators of accuracy, we offer 3 meta-analyses to help researchers and applied psychologists understand and interpret both consistencies and unique insights afforded by other-ratings of personality. These meta-analyses integrate findings based on 44,178 target individuals rated across 263 independent samples. Each meta-analysis assessed the accuracy of observer ratings, as indexed by interrater consensus/reliability (Study 1), self–other correlations (Study 2), and predictions of behavior (Study 3). The results show that although increased frequency of interacting with targets does improve accuracy in rating personality, informants' interpersonal intimacy with the target is necessary for substantial increases in other-rating accuracy. Interpersonal intimacy improved accuracy especially for traits low in visibility (e.g., Emotional Stability) but only minimally for traits high in evaluativeness (e.g., Agreeableness). In addition, observer ratings were strong predictors of behaviors. When the criterion was academic achievement or job performance, other-ratings yielded predictive validities substantially greater than and incremental to self-ratings. These findings indicate that extraordinary value can gained by using other-reports to measure personality, and these findings provide guidelines toward enriching personality theory. Various subfields of psychology in which personality variables are systematically assessed and utilized in research and practice can benefit tremendously from use of others' ratings to measure personality variables.

Using theory to evaluate personality and job-performance relations: A socioanalytic perspective.

The authors used socioanalytic theory to understand individual differences in people's performance at work. Specifically, if predictors and criteria are aligned by using theory, then the meta-analytic validity of personality measures exceeds that of atheoretical approaches. As performance assessment moved from general to specific job criteria, all Big Five personality dimensions more precisely predicted relevant criterion variables, with estimated true validities of .43 (Emotional Stability), .35 (Extraversion-Ambition), .34 (Agreeableness), .36 (Conscientiousness), and .34 (Intellect-Openness to Experience).

Big Five factors and facets and the prediction of behavior.

The authors compared the Big 5 factors of personality with the facets or traits of personality that constitute those factors on their ability to predict 40 behavior criteria. Both the broad factors and the narrow facets predicted substantial numbers of criteria, but the latter did noticeably better in that regard, even when the number of facet predictors was limited to the number of factor predictors. Moreover, the criterion variance accounted for by the personality facets often included large portions not predicted by the personality factors. The narrow facets, therefore, were able to substantially increase the maximum prediction achieved by the broad factors. The results of this study are interpreted as supporting a more detailed approach to personality assessment, one that goes beyond the measurement of the Big 5 factors alone.

Toward an interactionist taxonomy of personality and situations: An integrative situational—dispositional representation of personality traits.

This article has 2 goals: first, to present and test a hierarchical representation of personality that jointly incorporates both situational and personality (e.g., Big Five) factors into a trait conception, and second, to explicate the dimensions along which situations differ in their effect on responses, providing the conceptual and empirical groundwork for the development of a joint taxonomy of traits and situations. A study of the effects of situational differences on trait self-reports indicated that conscientiousness and agreeableness can be represented hierarchically, with lower levels jointly constrained by both personality content and situational breadth. This representation establishes a methodological framework allowing for the explanation of the ways that situations interact with personality to affect responses. Implications of this representation for personality theory and prediction to and from personality inventories are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
