The NEO-PI-3: a more readable revised NEO Personality Inventory

Use of the Revised NEO Personality Inventory (NEO-PI-R; Costa & McCrae, 1992) in adolescent samples has shown that a few respondents have difficulty with a subset of items. We identified 30 items that were not understood by at least 2% of adolescent respondents and 18 additional items with low item-total correlations, and we wrote 2 trial replacement items for each. We used self-report and observer rating data from 500 respondents aged 14 to 20 to select replacement items. The modified instrument retained the intended factor structure and showed slightly better internal consistency, cross-observer agreement, and readability (Flesch-Kincaid grade level = 5.3). The NEO-PI-3 appears to be useful in high school and college samples and may have wider applicability to adults as well.     

Replicating the five factor model of personality in a psychiatric sample

In this study we examined whether the factor structure and traits of the five-factor model of personality (FFM), derived from non-clinical samples, could be replicated in a sample of psychiatric patients. The revised NEO Personality Inventory (NEO PI-R) was administered to a study group of psychiatric patients (n=176). The test scores from these patients were intercorrelated, factor analyzed and the obtained factor structure was then compared to the factor structure of the normative data from the NEO PI-R. The factor structure from the psychiatric study group and that from the normative sample were virtually identical, with all five factors showing significant congruence. These results argue favorably for the clinical applicability of the FFM with psychiatric patients.     

Aesthetic Chills as a Universal Marker of Openness to Experience

Aesthetic chills are transient emotional responses to music or other experiences of beauty. Item 188 of the Revised NEO Personality Inventory (NEO-PI-R) asks respondents if they have experienced these chills, and in American samples it is one of the best definers of Openness to Experience, one of the five basic personality factors. As part of the NEO-PI-R, the item has been translated into over 40 languages, and an examination of back-translations suggests that the phenomenon can be expressed in all the languages examined. Data from the Personality Profiles of Cultures Project show that Item 188 is one of the best definers of Openness in most of the 51 cultures examined. Aesthetic chills appear to be a universal emotional experience, although the functions they serve and the mechanisms that account for them remain to be discovered.

Perceptions of Americans and the Iraq Invasion: Implications for Understanding National Character Stereotypes

This study examines perceptions of the "typical American" from 49 cultures around the world. Contrary to the ethnocentric bias hypothesis, we found strong agreement between in-group and out-group ratings on the American profile (assertive, open-minded, but antagonistic); Americans in fact had a somewhat less desirable view of Americans than did others. Within cultures, in-group ratings were not systematically more favorable than out-group ratings. The Iraq invasion had a slight negative effect on perceptions of the typical American, but people around the world seem to draw a clear distinction between U.S. foreign policy and the character of the American people. National character stereotypes appear to have a variety of sources and to be perpetuated by both cognitive mechanisms and socio-cultural forces.     

Rater Wealth Predicts Perceptions of Outgroup Competence

National income has a pervasive influence on the perception of ingroup stereotypes, with high status and wealthy targets perceived as more competent. In two studies we investigated the degree to which economic wealth of raters related to perceptions of outgroup competence. Raters’ economic wealth predicted trait ratings when (1) raters in 48 other cultures rated Americans’ competence and (2) Mexican Americans rated Anglo Americans’ competence. Rater wealth also predicted ratings of interpersonal warmth on the culture level. In conclusion, raters’ economic wealth, either nationally or individually, is significantly associated with perception of outgroup members, supporting the notion that ingroup conditions or stereotypes function as frames of reference in evaluating outgroup traits.     

A note on some measures of profile agreement

Profile similarity or agreement is increasingly used in personality research and clinical practice and has potential applications in many other fields of psychology. I compared 4 measures of profile agreement--the Pearson r, Cattell's (1949) r(p), McCrae's (1993) r(pa), and an intraclass correlation coefficient (double entry), ICC(DE)--using both broad factor and specific facet profiles. Matched versus mismatched self-ratings/other ratings on the NEO Personality Inventory-3 (McCrae, Costa, & Martin, 2005) were used as criteria. At the factor level, r(pa) and ICC(DE) were comparable, and both were superior to r(p) in distinguishing matched versus mismatched profiles. At the facet level, ICC(DE) was superior to the other coefficients. The Pearson r performed better than expected.     

Personality traits of Russians from the observer's perspective

Data were collected by the members of the Russian character and personality survey from 39 samples in 33 administrative areas of the Russian Federation. Respondents (N = 7065) identified an ethnically Russian adult or college‐aged man or woman whom they knew well and rated the target using the Russian observer rating version of the Revised NEO Personality Inventory, which measures neuroticism, extraversion, openness to experience, agreeableness and conscientiousness. Factor analyses within samples showed that the factor structure of an international sample combining data from 50 different cultures was well replicated in all 39 Russian samples. Sex differences replicated the known pattern in all samples, demonstrating that women scored higher than men on most of the neuroticism, openness, agreeableness and conscientiousness facet scales. Cross‐sectional analyses demonstrated consistent age differences for four factors: Older individuals compared to younger ones were less extraverted and open but more agreeable and conscientious. The mean levels of traits were similar in all 39 samples. Although in general personality traits in Russians closely followed the universal pattern, some reliable culture‐specific effects were also found that future studies can help interpret.

The five-factor model and its assessment in clinical settings.

Personality researchers have recently converged on the five-factor model as an adequate representation of the structure of personality traits. This article introduces the factors and the NEO Personality Inventory (NEO-PI), a questionnaire designed to measure the factors and some of the traits that define them. Data on the comprehensiveness of the model and on the reliability, validity, and stability of measures of the factors are reviewed, and correlations between scales from the NEO-PI and two instruments widely used in clinical practice (the Minnesota Multiphasic Personality Inventory [MMPI] and the Millon Clinical Multiaxial Inventory [MCMI]) are used to illustrate similarities and differences between normal and clinical assessment. Some issues regarding the clinical use of the five-factor model are discussed.     

Sources of structure: genetic, environmental, and artifactual influences on the covariation of personality traits

The phenotypic structure of personality traits has been well described, but it has not yet been explained causally. Behavior genetic covariance analyses can identify the underlying causes of phenotypic structure; previous behavior genetic research has suggested that the effects from both genetic and nonshared environmental influences mirror the phenotype. However, nonshared environmental effects are usually estimated as a residualterm that may also include systematic bias, such as that introduced by implicit personality theory. To reduce that bias, we supplemented data from Canadian and German twin studies with cross-observer correlations on the Revised NEO Personality Inventory. The hypothesized five-factor structure was found in both the phenotypic and genetic/familial covariances. When the residual covariance was decomposed into true nonshared environmental influences and method bias, only the latter showed the five-factor structure. True nonshared environmental influences are not structured as genetic influences are, although there was some suggestion that they do affect two personality dimensions, Conscientiousness and Love. These data reaffirm the value of behavior genetic analyses for research on the underlying causes of personality traits.     

Universal features of personality traits from the observer's perspective: data from 50 cultures

To test hypotheses about the universality of personality traits, college students in 50 cultures identified an adult or college-aged man or woman whom they knew well and rated the 11,985 targets using the 3rd-person version of the Revised NEO Personality Inventory. Factor analyses within cultures showed that the normative American self-report structure was clearly replicated in most cultures and was recognizable in all. Sex differences replicated earlier self-report results, with the most pronounced differences in Western cultures. Cross-sectional age differences for 3 factors followed the pattern identified in self-reports, with moderate rates of change during college age and slower changes after age 40. With a few exceptions, these data support the hypothesis that features of personality traits are common to all human groups.
