Personality profiles of cultures: aggregate personality traits

Personality profiles of cultures can be operationalized as the mean trait levels of culture members. College students from 51 cultures rated an individual from their country whom they knew well (N=12,156). Aggregate scores on Revised NEO Personality Inventory (NEO-PI-R) scales generalized across age and sex groups, approximated the individual-level 5-factor model, and correlated with aggregate self-report personality scores and other culture-level variables. Results were not attributable to national differences in economic development or to acquiescence. Geographical differences in scale variances and mean levels were replicated, with Europeans and Americans generally scoring higher in Extraversion than Asians and Africans. Findings support the rough scalar equivalence of NEO-PI-R factors and facets across cultures and suggest that aggregate personality profiles provide insight into cultural differences.     

Experimental manipulation of NEO-PI-R items.

Research assessing the relationship of the Five-factor model (FFM) of personality to personality disorder symptomatology has generally been consistent with theoretical expectations. Three exceptions, however, have been failures to confirm predicted associations of the NEO-Personality Inventory-Revised (NEO-PI-R) Conscientiousness scale with obsessive-compulsive personality disorder symptomatology, the NEO-PI-R Agreeableness scale with dependent symptomatology, and the NEO-PI-R Openness scale with schizotypal symptomatology. It was the hypothesis of this study that these findings might be due in part to a relative emphasis on adaptive rather than maladaptive variants of these domains of personality functioning within the NEO-PI-R. This hypothesis was tested by experimentally altering NEO-PI-R items to reverse their implications for maladaptiveness. The predicted correlations of the FFM were confirmed with the experimentally altered items in a sample of 86 adult psychiatric outpatients.

Commentary on Reconceptualizing Personality Disorder Categories Using Trait Dimensions

The present study examined Widiger and Lynam's (1998) hypothesis that psychopathy can be represented using the Five-Factor Model (FFM) of personality. Participants in the study consisted of 481 21-22-year-old men and women who are part of an ongoing longitudinal study. Psychopathy was assessed by the degree of similarity between an individual's NEO-PI-R and an expert-generated FFM psychopathy prototype. The expert-based prototype supported the account of Widiger and Lynam (1998), as did the correlations between the NEO-PI-R Psychopathy Resemblance Index (PRI) and the individual personality dimensions. The PRI was also related in predicted ways to measures of antisocial behavior, drug use, and psychopathology. The results support the contention that psychopathy can be understood as an extreme variant of common dimensions of personality, and underscore the utility of a dimensional model of personality disorders.     

Effects of response sets on NEO-PI-R scores and their relations to external criteria

Validity scales indicate the extent to which the results of a self-report inventory are a valid indicator of the test taker's psychological functioning. Validity scales generally are designed to detect the common response sets of positive impression management (underreporting, or faking good), negative impression management (overreporting, or faking bad), and random responding. The revised NEO Personality Inventory (NEO-PI-R; Costa & McCrae, 1992b) is a popular personality assessment tool based on the 5-factor model of personality and is used in a variety of settings. The NEO-PI-R does not include objective validity scales to screen for positive or negative impression management. The purpose of this study was to examine the utility of recently proposed validity scales for detecting these response sets on the NEO-PI-R (Schinka, Kinder, & Kremer, 1997) and to examine the effects of positive and negative impression management on correlations between the NEO-PI-R and external criteria (the Interpersonal Adjective Scale-Revised-B5 [Wiggins & Trapnell, 1997] and the NEO-PI-R Form R). The validity scales discriminated with reasonable accuracy between standard responding and the 2 response sets. Additionally, most correlations between the NEO-PI-R and external criteria were significantly lower when participants were dissimulating than when responding to standard instructions. It appears that response sets of positive and negative impression management may pose a significant threat to the external validity of the NEO-PI-R and that validity scales for their detection might be a useful addition to the inventory.     

On the usefulness of measures of normal personality for clinical assessment: evidence of the incremental validity of the Revised NEO Personality Inventory

As a means of examining the incremental validity of a normal personality measure in the prediction of selected Axis I and II diagnoses, 1,342 inpatient substance abusers completed the Revised NEO Personality Inventory (NEO-PI-R) and the Minnesota Multiphasic Personality Inventory--2 (MMPI-2) and were assessed with structured clinical interviews to determine diagnostic status. Results demonstrated that scores from the NEO-PI-R (a) were substantially related to the majority of diagnoses, accounting for between 8% and 26% of the variance in the diagnostic criteria; (b) explained an additional 3% to 8% of the variability beyond 28 selected MMPI-2 scale scores; (c) increased diagnostic classification an additional 7% to 23% beyond MMPI-2 scale scores; and (d) were significantly more useful when examined at the facet trait level than at the domain trait level. Implications for incorporating measures of normal personality into clinical assessment batteries are discussed.     

Thinking styles in relation to personality traits: an investigation of the Thinking Styles Inventory and NEO-PI-R

This study is an investigation of the Sternberg-Wagner Thinking Style Inventory (TSI), with regard to cross-cultural replication and relation to the five-factor personality model (FFM). TSI and NEO-PI-R were administered to 107 participants from USA and 114 participants from Norway. Inter-correlations between NEO-PI-R dimensions and TSI-scales and factors were not very strong, few exceeding 0.40, and the correlations were in predicted directions. Joint factor analyses of TSI and NEO-PI-R showed that TSI covers variance that NEO-PI-R does not explain. Thus, it is argued that the thinking styles give an independent contribution beyond FFM dimensions. However, TSI did not relate to FFM in the same manner in the two samples. Finally, the TSI-scales and factors were replicable across samples by Procrustes rotation. The question whether thinking style may be regarded as a valid and reliable construct is discussed.     

Predicting dimensions of personality disorder from domains and facets of the Five-Factor Model

We compared the utility of several trait models for describing personality disorder in a heterogeneous clinical sample (N = 94). Participants completed the Schedule for Nonadaptive and Adaptive Personality (SNAP; Clark, 1993b), a self-report measure that assesses traits relevant to personality disorder, and two measures of the Five-Factor Model: the Revised NEO Personality Inventory (NEO-PI-R; Costa and McCrae, 1992) and the Big Five Inventory (BFI; John, Donahue, & Kentle, 1991). Regression analyses indicated substantial overlap between the SNAP scales and the NEO-PI-R facets. In addition, use of the NEO-PI-R facets afforded substantial improvement over the Five-Factor Model domains in predicting interview-based ratings of DSM-IV personality disorder (American Psychiatric Association, 1994), such that the NEO facets and the SNAP scales demonstrated roughly equivalent levels of predictive power. Results support assessment of the full range of NEO-PI-R facets over the Five-Factor Model domains for both research and clinical use.     

The hoarding dimension of OCD: psychological comorbidity and the five-factor personality model

Although hoarding has been associated with several psychological disorders, it is most frequently linked to obsessive-compulsive disorder (OCD). The present study assessed hoarding obsessions and compulsions in 204 individuals with OCD, and evaluated how hoarding was related to obsessive-compulsive symptom severity, psychological comorbidity, and personality as measured by the five-factor model. Results indicated that hoarding in OCD is a dimensional variable that is positively associated with dysphoria, total number of lifetime Axis I disorders, and lifetime histories of bipolar I, PTSD, and body dysmorphic disorder. Hoarding was negatively correlated with the NEO-Personality Inventory-Revised (NEO-PI-R) factor of Conscientiousness and positively associated with the NEO-PI-R factor of Neuroticism. When all personality and psychopathology variables were entered into a regression equation, dysphoria, bipolar II disorder, Conscientiousness, age, and Extraversion emerged as significant predictors of hoarding severity. Recommendations are made for clinicians and for future research.     

Anxiety sensitivity and the five-factor model of personality.

Relations between anxiety sensitivity (AS) and the higher-order and lower-order dimensions of the 'Big Five' model of personality were examined in 317 university students. AS was significantly associated with a number of personality domains and facets of the NEO-PI-R. Regression analyses indicated that only the higher-order domains of neuroticism and extraversion (negatively) and the lower-order N facets of anxiety and self-consciousness, significantly predicted AS. Three lower-order factors within AS were identified and were also compared to NEO-PI-R domains and facets. In a hierarchical regression, the three AS factors significantly predicted variance in a measure of panic-related anxiety after the effects of the six N facets were statistically controlled. Results are discussed in the context of previous work with a Big Three taxonomy of personality and implications for understanding the nature and possible origins of AS are outlined.     

Cross-cultural replication of the five-factor model and comparison of the NEO-PI-R and MMPI-2 PSY-5 scales in a Dutch psychiatric sample

The authors investigated cross-cultural replicability of the five-factor model (FFM) of personality as represented by the revised NEO Personality Inventory (NEO-PI-R; P. T. Costa & R. R. McCrae, 1992) in a sample of 423 Dutch psychiatric patients. Also, NEO-PI-R domain scales were compared with the Personality Psychopathology Five (PSY-5; A. R. Harkness & J. L. McNulty, 1994) scales of the Minnesota Multiphasic Personality Inventory-2 (J. N. Butcher, W. G. Dahlstrom, J. R. Graham, A. Tellegen, & B. Kaemmer, 2002). Principal-components analysis with procrustean rotation confirmed the hypothesized structural similarity of the present sample with the U.S. normative factor scores. All of the hypothesized relations between NEO-PI-R and PSY-5 scales were confirmed. The results provide evidence for cross-cultural replicability of the FFM and for validity of the NEO-PI-R and PSY-5 constructs in the psychological assessment of psychiatric patients.     

Convergence of Vocational Interests and Personality: Examples in an Adolescent Gifted Sample

This investigation explored the convergence between vocational interests as measured by the Strong Interest Inventory (Hansen & Campbell, 1985) and two competing personality models: the Big Five as measured by the NEO Personality Inventory-Revised (NEO-PI-R) (Costa & McCrae, 1992) and the Big Three as measured by the Multidimensional Personality Questionnaire (MPQ) (Tellegen, 1982; Tellegen & Waller, in press). The participants were 323 gifted adolescents. The authors predicted that specific NEO-PI-R facet scales and specific MPQ primary scales would add meaningful variance to the prediction of hypothesized Basic Interest Scales (BISs) on the Strong after the variation due to the respective Big Five or Big Three factors was removed. The predictions were largely supported. Moreover, this study provided additional evidence regarding convergence of Holland's Big Six and the Big Five model of personality. This study could serve to prompt a new generation of studies relating vocational interests and personality.     

Domains and facets: hierarchical personality assessment using the revised NEO personality inventory

Personality traits are organized hierarchically, with narrow, specific traits combining to define broad, global factors. The Revised NEO Personality Inventory (NEO-PI-R; Costa & McCrae, 1992c) assesses personality at both levels, with six specific facet scales in each of five broad domains. This article describes conceptual issues in specifying facets of a domain and reports evidence on the validity of NEO-PI-R facet scales. Facet analysis-the interpretation of a scale in terms of the specific facets with which it correlates-is illustrated using alternative measures of the five-factor model and occupational scales. Finally, the hierarchical interpretation of personality profiles is discussed. Interpretation on the domain level yields a rapid understanding of the individual interpretation of specific facet scales gives a more detailed assessment.     

Evaluating NEO Personality Inventory-Revised profiles in veterans with personality disorders

Fifty-one psychiatric, veteran outpatients were assessed for personality disorders on the Structured Clinical Interview for DSM-IV Axis II Disorders (SCID-II; First, Gibbon, Spitzer, Williams, & Benjamin, 1997a) and were also administered the NEO Personality Inventory-Revised (NEO-PI-R; Costa & McCrae, 1992). Results were compared to Trull and Widiger's (1997) hypotheses about the profiles of such patients and similar past studies. Correlations between NEO-PI-R facets and SCID-II personality disorder symptom clusters generally occurred in the expected direction. Facets hypothesized to be associated with a given personality disorder were able to predict variance in their respective SCID-II personality disorder scores for seven of ten personality disorders. In general, results support the facet-level conceptualizations of these disorders, except for Obsessive-Compulsive Personality Disorder.     

Competition and cooperation in the five-factor model: individual differences in achievement orientation

The authors investigated the relationship between basic achievement orientations of competition and cooperation and the five-factor model of personality as measured by the Revised NEO Personality Inventory (NEO-PI-R; P. T. Costa & R. R. McCrae, 1992). They examined 2 types of competition: hypercompetition (R. M. Ryckman, B. Thornton, & J. C. Butler, 1994) and personal development competition (R. M. Ryckman, M. Hammer, L. M. Kaczor, & J. A. Gold, 1996), as conceptualized by K. Horney (1937). In a sample of 251 young adults, 14% to 38% of the variance in achievement orientations was collectively predicted by NEO-PI-R domain scales. Of NEO-PI-R predictors, Agreeableness was most important in characterizing differences between various achievement orientations; Agreeableness was negatively related to hypercompetition, positively related to cooperation, and unrelated to personal development competition. Extraversion was positively related to both cooperation and personal development competition but was unrelated to hypercompetition. In contrast, Openness and Conscientiousness were least helpful in differentiating among achievement orientations. These findings support the useful application of the NEO-PI-R in achievement research and highlight competition and cooperation as interpersonally laden achievement orientations.     

The Italian version of the NEO PI-R: conceptual and empirical support for the use of targeted rotation

Earlier cross-cultural research on replicability of the Revised NEO Personality Inventory (NEO-PI-R) suggested that personality trait structure is universal, but a recent study using an Italian translation has challenged this position. The present article re-examines the psychometric properties of the Italian NEO-PI-R and discusses the importance of orthogonal Procrustes rotation when the replicability of complex factor structures is tested. The arguments are supported by data from a slightly modified translation of the NEO-PI-R, which was administered to 575 Italian subjects. These data show a close replication of the American normative factor structure when targeted rotation is used. Further, the validity of the Italian NEO-PI-R is supported by external correlates, such as demographic variables (age, sex, education), depression, and affect scales.     

Positive and negative symptoms of schizotypy and the Five-factor model: a domain and facet level analysis

In this study, we investigated the Five-factor model in the concurrent prediction of positive symptom schizotypy as measured by the Magical Ideation (Eckblad & Chapman, 1983) and Perceptual Aberration (Chapman, Chapman, & Raulin, 1978) scales and negative symptom schizotypy as measured by the Physical Anhedonia (Chapman, Chapman, & Raulin, 1976) and Revised Social Anhedonia (Eckblad, Chapman, Chapman, & Mishlove, 1982; Mishlove & Chapman, 1985) scales. Previous studies suggest that these measures reflect the core symptoms found in schizotypal and schizoid personality disorder (Bailey, West, Widiger, & Freiman, 1993). Negative symptoms were significantly predicted by Neuroticism (+), Extraversion (-), Openness (-), and Agreeableness (-) domains of the Revised NEO Personality Inventory (NEO-PI-R; Costa & McCrae, 1992). Additionally, positive symptoms were significantly predicted by Neuroticism (+), Openness (+), and Agreeableness (-). In addition, we examined the validity of lower order traits in de- scribing these symptoms of character pathology. These findings lend further support for the use of domain and facet scales of the NEO-PI-R in the identification of personality pathology.     

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.     

Psychopathy and the Five-factor model of personality: a replication and extension

It has recently been argued that psychopathy can be understood and represented using common dimensions of personality taken from the Five-factor model (FFM). In this research, we examined this possibility by using the Revised NEO Personality Inventory (NEO-PI-R; Costa & McCrae, 1992) to assess psychopathy in an undergraduate sample. Specifically, we matched individuals' NEO-PI-R profiles with an expert-generated psychopathy prototype to yield a psychopathy score. These scores were correlated with self-reports of drug use, delinquency, risky sex, aggression, and several laboratory tasks. FFM psychopathy was significantly related to all forms of deviance, although the effects tended to be small in size. Moreover, individuals who more closely resembled the prototypic FFM psychopath were more aggressive in a laboratory aggression task, less willing to delay gratification in a time discounting task, and demonstrated a preference for aggressive responses in a social information-processing paradigm.
