Bridging the gap with the five-factor model.

Comments on the original article Personality traits and the classification of mental Disorders: Toward a more complete integration in DSM–5 and an empirical model of psychopathology by Robert F. Krueger and Nicholas R. Eaton (see record 2010-13810-003). Some researchers had hoped the forthcoming Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) would ask psychiatrists (and the clinical psychologists and researchers who are also tied to the DSM) to leap the gap and embrace a trait-based taxonomy of personality pathology (Widiger & Trull, 2007). Krueger and Eaton (pp. 97–118, this issue) take a more pragmatic stance: They hope to coax psychiatrists across by introducing personality dimensions as an adjunct to familiar PD types; they envision that DSM-5 might serve “as a bridge” (p. 110, this issue) to a fully dimensional Diagnostic and Statistical Manual of Mental Disorders, Sixth Edition (DSM-6). We acknowledge the wisdom of this strategy and suggest ways to strengthen it. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

From catalog to classification: Murray's needs and the five-factor model.

The alphabetical list of needs described by Murray (1938) has formed the basis for a number of inventories, including the Personality Research Form (PRF; Jackson, 1984). In an attempt to provide a more meaningful classification of the Murray needs, the scales of Form E of the PRF were examined in relation to the NEO Personality Inventory (NEO-PI; Costa & McCrae, 1985), which measures the five major dimensions of normal personality. Data from 296 adult men and women showed hypothesized correlations on the level of individual scales, and suggested that the Desirability scale of the PRF measures substantive traits when used in a volunteer sample. Although the NEO-PI and PRF have different conceptual origins and measure somewhat different aspects of personality, a joint factor analysis showed that the needs measured by the PRF can be meaningfully organized within the framework of the five-factor model. Use of this taxonomy can facilitate communication between motivational and trait psychologists, and supplement the dynamic interpretation of motives with a second level of interpretation that points to related affective, interpersonal, and experiential styles.

Validation of the five-factor model of personality across instruments and observers.

Two data sources—self reports and peer ratings—and two instruments—adjective factors and questionnaire scales—were used to assess the five-factor model of personality. As in a previous study of self-reports (McCrae & Costa, 1985b), adjective factors of neuroticism, extraversion, openness to experience, agreeableness–antagonism, and conscientiousness–undirectedness were identified in an analysis of 738 peer ratings of 275 adult subjects. Intraclass correlations among raters, ranging from .30 to .65, and correlations between mean peer ratings and self-reports, from .25 to .62, showed substantial cross-observer agreement on all five adjective factors. Similar results were seen in analyses of scales from the NEO Personality Inventory. Items from the adjective factors were used as guides in a discussion of the nature of the five factors. These data reinforce recent appeals for the adoption of the five-factor model in personality research and assessment. (69 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The structure of musical preferences: A five-factor model.

Music is a cross-cultural universal, a ubiquitous activity found in every known human culture. Individuals demonstrate manifestly different preferences in music, and yet relatively little is known about the underlying structure of those preferences. Here, we introduce a model of musical preferences based on listeners' affective reactions to excerpts of music from a wide variety of musical genres. The findings from 3 independent studies converged to suggest that there exists a latent 5-factor structure underlying music preferences that is genre free and reflects primarily emotional/affective responses to music. We have interpreted and labeled these factors as (a) a Mellow factor comprising smooth and relaxing styles; (b) an Unpretentious factor comprising a variety of different styles of sincere and rootsy music such as is often found in country and singer–songwriter genres; (c) a Sophisticated factor that includes classical, operatic, world, and jazz; (d) an Intense factor defined by loud, forceful, and energetic music; and (e) a Contemporary factor defined largely by rhythmic and percussive music, such as is found in rap, funk, and acid jazz. The findings from a fourth study suggest that preferences for the MUSIC factors are affected by both the social and the auditory characteristics of the music.

A meta-analysis of the five-factor model of personality and academic performance.

This article reports a meta-analysis of personality–academic performance relationships, based on the 5-factor model, in which cumulative sample sizes ranged to over 70,000. Most analyzed studies came from the tertiary level of education, but there were similar aggregate samples from secondary and tertiary education. There was a comparatively smaller sample derived from studies at the primary level. Academic performance was found to correlate significantly with Agreeableness, Conscientiousness, and Openness. Where tested, correlations between Conscientiousness and academic performance were largely independent of intelligence. When secondary academic performance was controlled for, Conscientiousness added as much to the prediction of tertiary academic performance as did intelligence. Strong evidence was found for moderators of correlations. Academic level (primary, secondary, or tertiary), average age of participant, and the interaction between academic level and age significantly moderated correlations with academic performance. Possible explanations for these moderator effects are discussed, and recommendations for future research are provided. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Clarification of the five-factor model with the Abridged Big Five Dimensional Circumplex.

Shows how the Abridged Big Five Dimensional Circumplex (AB5C; W. K. Hofstee, et al; see PA, Vol 79:39188 ) clarifies disputes about the Big Five or 5-factor model. Trait ratings from instruments representing 4 versions of the Big Five (L. R. Goldberg, see PA, Vol 79:25730; R. Hogan and J. A. Johnson, 1981; R. R. McCrae and P. T. Costa, see PA, Vols 73:3750 and 74:15614; and W. T. Norman, 1963) were subjected to separate AB5C analyses for 2,148 American and 1,285 German Ss. Replicated results formed standard designation codes representing trait adjectives' primary and secondary factor loadings. These codes unveiled the unique coloring imparted by secondary loadings to different scales proffered by researchers to represent the 5 factors.

The Estonian Self-Consciousness Scale and its relation to the five-factor model of personality

This article reports on the current state of our efforts to shed light on the origin and evolution of linguistic diversity using synthetic modeling and artificial life techniques. We construct a simple abstract model of a communication system that has been designed with regard to referential signaling in nonhuman animals. We analyze the evolutionary dynamics of vocabulary sharing based on these experiments. The results show that mutation rates, population size, and resource restrictions define the classes of vocabulary sharing. We also see a dynamic equilibrium, where two states, a state with one dominant shared word and a state with several dominant shared words, take turns appearing. We incorporate the idea of the abstract model into a more concrete situation and present an agent-based model to verify the results of the abstract model and to examine the possibility of using linguistic diversity in the field of distributed AI and robotics. It has been shown that the evolution of linguistic diversity in vocabulary sharing will support cooperative behavior in a population of agents.     

An alternative to the search for single polymorphisms: Toward molecular personality scales for the five-factor model.

There is growing evidence that personality traits are affected by many genes, all of which have very small effects. As an alternative to the largely unsuccessful search for individual polymorphisms associated with personality traits, the authors identified large sets of potentially related single nucleotide polymorphisms (SNPs) and summed them to form molecular personality scales (MPSs) with from 4 to 2,497 SNPs. Scales were derived from two thirds of a large (N = 3,972) sample of individuals from Sardinia who completed the Revised NEO Personality Inventory (P. T. Costa, Jr., & R. R. McCrae, 1992) and were assessed in a genomewide association scan. When MPSs were correlated with the phenotype in the remaining one third of the sample, very small but significant associations were found for 4 of the 5e personality factors when the longest scales were examined. These data suggest that MPSs for Neuroticism, Openness to Experience, Agreeableness, and Conscientiousness (but not Extraversion) contain genetic information that can be refined in future studies, and the procedures described here should be applicable to other quantitative traits.

The structure of interpersonal traits: Wiggins's circumplex and the five-factor model.

Using a sample of 315 adult men and women, self-reports on Wiggins's revised Interpersonal Adjective Scales were jointly factored with self-reports, peer ratings, and spouse ratings on the NEO Personality Inventory to examine the relations between the two models. Results suggest that the interpersonal circumplex is defined by the two dimensions of Extraversion and Agreeableness, and that the circular ordering of variables is not an artifact of response biases or cognitive schemata. Circumplex and dimensional models appear to complement each other in describing the structure of personality, and both may be useful to social psychologists in understanding interpersonal behavior.

Using the five-factor model to identify a new personality disorder domain: The case for experiential permeability.

Two studies were conducted to demonstrate that maladaptive aspects of high and low Openness to Experience were related to characterological impairment and that this aspect of personality may define a new domain of personality dysfunction. The 55-item Experiential Permeability Inventory (EPI; containing 4 scales) was developed and demonstrated to have acceptable psychometric properties. Evidence of convergent, discriminant, and incremental validity was provided. These studies provide a methodological framework for identifying and developing aspects of personality dysfunction that can expand the comprehensiveness of the current set of Axis II disorders. Theoretical implications of the EPI are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The five-factor model of personality as a framework for personality-health research.

The NEO Personality Inventory and representative personality scales drawn from health psychology were administered to 2 samples of male military recruits (Ns?=?296 and 502). Factor analysis of health-related personality scales revealed 3 conceptually meaningful domains. Examination of these domains and their constituent scales, with reference to the 5-factor model of personality, permits 3 general conclusions. First, most health-relevant dimensions and scales appear to be complex mixtures of broad personality domains. Second, variation in many health-related personality instruments is explained to a significant degree by the 5-factor model. Third, 2 of the 5 personality domains (i.e., conscientiousness and openness) appear to be substantially neglected in health psychology research.

Private self-consciousness and the five-factor model of personality: Distinguishing rumination from reflection.

A distinction between ruminative and reflective types of private self-attentiveness is introduced and evaluated with respect to L. R. Goldberg's (1982) list of 1,710 English trait adjectives (Study 1), the five-factor model of personality (FFM) and A. Fenigstein, M. F. Scheier, and A. Buss's (1976) Self-Consciousness Scales (Study 2), and previously reported correlates and effects of private self-consciousness (PrSC; Studies 3 and 4). Results suggest that the PrSC scale confounds two unrelated, motivationally distinct dispositions—rumination and reflection—and that this confounding may account for the "self-absorption paradox" implicit in PrSC research findings: Higher PrSC scores are associated with more accurate and extensive self-knowledge yet higher levels of psychological distress. The potential of the FFM to provide a comprehensive framework for conceptualizing self-attentive dispositions, and to order and integrate research findings within this domain, is discussed.

Are indigenous personality dimensions culture specific? Philippine inventories and the five-factor model.

The authors addressed the culture specificity of indigenous personality constructs, the generalizability of the 5-factor model (FFM), and the incremental validity of indigenous measures in a collectivistic culture. Filipino college students (N=508) completed 3 indigenous inventories and the Filipino version of the Revised NEO Personality Inventory (NEO-PI-R). On the basis of the factor and regression analyses, they concluded that (a) most Philippine dimensions are well encompassed by the FFM and thus may not be very culture specific; (b) a few indigenous constructs are less well accounted for by the FFM; these constructs are not unknown in Western cultures, but they may be particularly salient or composed somewhat differently in the Philippines; (c) the structure of the NEO-PI-R FFM replicates well in the Philippines; and (d) Philippine inventories add modest incremental validity beyond the FFM in predicting selected culture-relevant criteria.

Validity of observer ratings of the five-factor model of personality traits: A meta-analysis.

Conclusions reached in previous research about the magnitude and nature of personality–performance linkages have been based almost exclusively on self-report measures of personality. The purpose of this study is to address this void in the literature by conducting a meta-analysis of the relationship between observer ratings of the five-factor model (FFM) personality traits and overall job performance. Our results show that the operational validities of FFM traits based on observer ratings are higher than those based on self-report ratings. In addition, the results show that when based on observer ratings, all FFM traits are significant predictors of overall performance. Further, observer ratings of FFM traits show meaningful incremental validity over self-reports of corresponding FFM traits in predicting overall performance, but the reverse is not true. We conclude that the validity of FFM traits in predicting overall performance is higher than previously believed, and our results underscore the importance of disentangling the validity of personality traits from the method of measurement of the traits.

The five-factor model of personality traits and organizational citizenship behaviors: A meta-analysis.

Using meta-analytic tests based on 87 statistically independent samples, we investigated the relationships between the five-factor model (FFM) of personality traits and organizational citizenship behaviors in both the aggregate and specific forms, including individual-directed, organization-directed, and change-oriented citizenship. We found that Emotional Stability, Extraversion, and Openness/Intellect have incremental validity for citizenship over and above Conscientiousness and Agreeableness, 2 well-established FFM predictors of citizenship. In addition, FFM personality traits predict citizenship over and above job satisfaction. Finally, we compared the effect sizes obtained in the current meta-analysis with the comparable effect sizes predicting task performance from previous meta-analyses. As a result, we found that Conscientiousness, Emotional Stability, and Extraversion have similar magnitudes of relationships with citizenship and task performance, whereas Openness and Agreeableness have stronger relationships with citizenship than with task performance. This lends some support to the idea that personality traits are (slightly) more important determinants of citizenship than of task performance. We conclude with proposed directions for future research on the relationships between FFM personality traits and specific forms of citizenship, based on the current findings.

Relationship between the five-factor model of personality and Axis I disorders in a nonclinical sample.

The relationship between the 5-factor model (FFM) of personality and Axis I disorders was evaluated in a nonclinical sample of 468 young adults. In general, scores on the 5 personality dimensions of neuroticism, extraversion, openness to experience, agreeableness, and conscientiousness (assessed via the NEO Five-Factor Inventory) distinguished Ss with and without a variety of Axis I diagnoses from the Diagnostic and Statistical Manual of Mental Disorders-III-Revised (DSM-III-R). In several instances, results indicate that scores on these dimensions were differentially sensitive to diagnosis. Furthermore, scores on these 5 personality dimensions accounted for unique variance in several Axis I diagnoses above and beyond that accounted for by a general measure of current psychopathological symptoms. These results support the utility of the FFM of personality in Axis I diagnostic assessment. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
