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.

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.

On the invalidity of validity scales: Evidence from self-reports and observer ratings in volunteer samples.

Because of the potential for bias and error in questionnaire responding, many personality inventories include validity scales intended to correct biased scores or identify invalid protocols. The authors evaluated the utility of several types of validity scales in a volunteer sample of 72 men and 106 women who completed the Revised NEO Personality Inventory (NEO-PI-R; P. T. Costa and R. R. McCrae, 1992) and the Multidimensional Personality Questionnaire (MPQ; A. Tellegen, 1978/1982) and were rated by 2 acquaintances on the observer form of the NEO-PI-R. Analyses indicated that the validity indexes lacked utility in this sample. A partial replication (N?=?1,728) also failed to find consistent support for the use of validity scales. The authors illustrate the use of informant ratings in assessing protocol validity and argue that psychological assessors should limit their use of validity scales and seek instead to improve the quality of personality assessments.

Cross-cultural personality assessment in psychiatric populations: The NEO-PI—R in the People's Republic of China.

The Revised NEO Personality Inventory (NEO-PI—R) is a measure of the 5-factor model developed on volunteer samples in the United States. To examine its validity in a non-Western, psychiatric sample, an existing Chinese translation was modified for use in the People's Republic of China (PRC). The instrument was administered to 2,000 psychiatric in- and outpatients at 13 sites throughout the PRC. Internal consistency was low for some facet scales, but retest reliability was adequate and the hypothesized factor structure was clearly recovered. Correlations with age, California Psychological Inventory scales, and spouse ratings supported the validity of NEO-PI—R scales, and diagnostic subgroups showed meaningful personality profiles. The 5-factor model appears to be useful for the assessment of personality among Chinese psychiatric patients. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

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.

Genetic and environmental structure of the Tridimensional Personality Questionnaire: Three or four temperament dimensions?

Previous phenotypic factor analyses suggest that C. R. Cloninger's Tridimensional Personality Questionnaire (TPQ; 1987) assesses 4 rather than 3 temperament dimensions. The purpose of this study was to determine whether Cloninger's revised 4-factor model showed incremental validity over his original model, and to investigate the convergent and discriminant validity of Cloninger's dimensions in comparison to the personality dimensions proposed by H. J. Eysenck (1981) and J. A. Gray (1970). The sample included 2,420 women and 870 men (aged 50-96) from a volunteer population-based sample of twins. Joint phenotypic factor analyses supported Cloninger's 4-dimensional temperament model. A 4-dimensional genetical factor structure was also confirmed in genetic analyses of the TPQ higher order dimensions in women. For men only 3 genetic factors were necessary to explain the genetic variance among the TPQ dimensions. (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.

Psychometric characteristics and clinical correlates of NEO-PI-R fearless dominance and impulsive antisociality in the Collaborative Longitudinal Personality Disorders Study.

[Correction Notice: An erratum for this article was reported online in Psychological Assessment on September 26 2011 (see record 2011-21951-001). The Appendix should have read: Fearless Dominance: 7*, 11, 16*, 37, 46, 71, 72, 102*, 127*, 132, 144, 152, 162*, 166, 192, 227, 232 Impulsive Antisociality: 14, 30, 44*, 45, 50*, 60*, 65*, 66, 95, 99, 159, 169, 189, 201, 205, 229, 240* * Indicates a reverse-scored item (based on original item content). NEO-PI-R = NEO Personality Inventory–Revised (Costa & McCrae, 1992).] This study evaluates the validity of derived measures of the psychopathic personality traits of Fearless Dominance and Impulsive Antisociality from the NEO Personality Inventory–Revised (NEO-PI-R; Costa & McCrae, 1992) using data from the Collaborative Longitudinal Personality Disorders Study (baseline N = 733). These 3 issues were examined: (a) the stability of the measures over a 10-year interval, (b) their criterion-related validity, and (c) their incremental validity relative to an alternative NEO-PI-R profile-rating approach for assessing psychopathy. NEO-PI-R Fearless Dominance and Impulsive Antisociality scales were relatively stable across 10 years and demonstrated differential associations with measures of personality pathology and psychopathology generally consistent with past research and theoretical considerations. Moreover, these measures demonstrated an appreciable degree of incremental validity over the NEO-PI-R profile-rating approach. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Personality and happiness: A national-level analysis.

The possibility of national personality traits could explain national subjective well-being (SWB) is controversial, with many researchers arguing that traits are irrelevant to any national-level analysis. The weaknesses of this standpoint are reviewed, followed by a series of empirical investigations. Using Eysenck's 3-factor model (H. J. Eysenck & S. B. G. Eysenck, 1975) and P. T. Costa and R. M. McCrae's (1992b) 5-factor model, the authors found that Neuroticism and Extraversion correlated significantly with national SWB. Lie scale scores were also related strongly to national SWB. Neuroticism and Extraversion incrementally predicted SWB above gross national product per capita. The strength of these results indicated that personality can have stronger relationships at national levels of analysis than at the individual level. National personality traits appear to be unwisely neglected, having considerable but largely unconsidered explanatory power. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Examining the construct validity of the Eating Disorder Inventory.

The construct validity of the Eating Disorder Inventory (EDI) was examined in 3 samples. An archival clinic sample (n=318) of women completed the EDI, a structured interview, and the Millon Clinical Multiaxial Inventory--II (MCMI-II). Confirmatory factor analyses (CFAs) indicated that neither null nor 1-factor models of the EDI fit item-level or item-parcel data. The proposed 8-factor model did not fit at the item level but did fit item-parcel data. Reliability estimates of the 8 scales ranged from .82 to .93, and low-to-moderate interscale correlations among the eating and weight-related scales provided partial support for convergent validity. EDI personality scales showed moderate interscale correlations and were associated with MCMI-II scales. A final CFA of the EDI scales supported a 2-factor model (Eating and Weight, Personality) of the 8 EDI scales. Strong associations between depression and several EDI scale scores were found in a treatment study sample (n=50). The archival clinic sample scored significantly higher on the 8 EDI scales than the nonpatient college comparison sample (n=487). (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Evaluating replicability of factors in the Revised NEO Personality Inventory: Confirmatory factor analysis versus Procrustes rotation.

Despite the empirical robustness of the 5-factor model of personality, recent confirmatory factor analyses (CFAs) of NEO Personality Inventory (NEO-PI) data suggest they do not fit the hypothesized model. In a replication study of 229 adults, a series of CFAs showed that Revised NEO-PI scales are not simple-structured but do approximate the normative 5-factor structure. CFA goodness-of-fit indices, however, were not high. Comparability analyses showed that no more than 5 factors were replicable, which calls into question some assumptions underlying the use of CFA. An alternative method that uses targeted rotation was presented and illustrated with data from Chinese and Japanese versions of the Revised NEO-PI that clearly replicated the 5-factor structure.

Self-rating scales reveal psychopathy

Psychopathy is regarded as a dimensional concept--i.e., a person can be more or less psychopathic. This approach enables psychopathy to be measured with reliable, validated personality scales, and to be related to impairment of serontonergic function in the brain. Several personality inventories are described in the article, especially the Karolinska Scales of Personality, the Zuckerman Sensation Seeking Scales, form V, the Eysenck Personality Questionnaire, including an impulsiveness scale from the IVE (Impulsiveness-Venturesomeness-Empathy) inventory, and the old dimensional scale, the Marke-Nyman Personality Temperament scale based on the personality theory of Henrik Sj?bring. In this way both old and new, and both Swedish and foreign personality concepts are linked together. Personality scales are easy to use and enable better stability and validity of results to be attained.     

Normal personality assessment in clinical practice: The NEO Personality Inventory.

Personality psychologists from a variety of theoretical perspectives have recently concluded that personality traits can be summarized in terms of a 5-factor model. This article describes the NEO Personality Inventory (NEO–PI), a measure of these 5 factors and some of the traits that define them, and its use in clinical practice. Recent studies suggest that NEO–PI scales are reliable and valid in clinical samples as in normal samples. The use of self-report personality measures in clinical samples is discussed, and data from 117 "normal" adult men and women are presented to show links between the NEO–PI scales and psychopathology as measured by D. N. Jackson's (1989) Basic Personality Inventory and L. Morey's (1991) Personality Assessment Inventory. The authors argue that the NEO–PI may be useful to clinicians in understanding the patient, formulating a diagnosis, establishing rapport, developing insight, anticipating the course of therapy, and selecting the optimal form of treatment for the patient.

Confirmatory factor analysis of the M5-50: An implementation of the International Personality Item Pool item set.

Goldberg’s International Personality Item Pool (IPIP; Goldberg, 1999) provides researchers with public-domain, free-access personality measurement scales that are proxies of well-established published scales. One of the more commonly used IPIP sets employs 50 items to measure the 5 broad domains of the 5-factor model, with 10 items per factor. The M5-50 (McCord, 2002) is a specific ordering and presentation of this 50-item set. Using data from a sample of 760 faculty, staff, and students at a midsized university, the authors assessed the reliability and construct validity of the M5-50. Cronbach’s alphas on the 5 scales ranged from acceptable to excellent. Confirmatory factor analysis indicated reasonably good model fit. Researchers who wish to measure personality would be well advised to consider using the M5-50. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

An examination of the structure of self-report psychopathy measures and their relations with general traits and externalizing behaviors.

Self-report assessment of psychopathy is plagued by inconsistencies among the relations of the various psychopathy factors. We examined the factor structure of 3 prominent self-report measures of psychopathy—the Self-Report Psychopathy Scale–III (SRP–III; Williams, Paulhus, & Hare, 2007), the Levenson Self-Report Psychopathy Scale (LSRP; Levenson, Kiehl, & Fitzpatrick, 1995), and the Psychopathic Personality Inventory–R (PPI–R; Lilienfeld & Widows, 2005). A coherent 4-factor structure resulted from conducting an exploratory factor analysis (EFA) of the psychopathy subscales along with the domains from the five-factor model. Two of these factors were consistent with traditional conceptualizations of a 2-factor structure of psychopathy (i.e., Factor 1, which loaded negatively with Agreeableness; Factor 2, which loaded negatively with Conscientiousness), while 2 additional factors emerged, 1 of which emphasized low Neuroticism and 1 of which emphasized traits related to novelty/reward-seeking and dominance-related personality traits (high Extraversion). We also investigated the relations of these factors with a variety of externalizing behaviors (EB). The psychopathy scales indicative of interpersonal antagonism (i.e., Factor 1) were most consistently and strongly related to EB. Our findings are discussed in terms of the importance of a trait-based perspective in the assessment of psychopathy. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Adjustment to residential placement in Alzheimer disease patients: does premorbid personality matter?

AIM: To evaluate the influence of premorbid personality on adaptation to placement in a long-term care facility. SUBJECTS: Twenty-eight persons with probable Alzheimer disease (AD) residing in an academically affiliated nursing home for 6-9 months. METHODS: Premorbid personality was described retrospectively by two informants for each resident using the revised NEO Personality Inventory (NEO-PI-R). Standardized tests and rating scales were used on admission to the facility to assess cognition, mood state, physical dependency and general health. Nurses rated each AD resident's social behaviour, participation in activities and quality of sleep. RESULTS: Poorer adjustment was associated with more severe dementia but better physical health. None of the NEO-PI-R domain scores predicted adjustment. CONCLUSIONS: Contrary to popular belief, premorbid personality is relatively inconsequential for an AD patient's adaptation to a long-term care facility.     

Factor structure of the Psychopathic Personality Inventory (PPI): Findings from a large incarcerated sample.

Exploratory factor analysis (EFA) of the Psychopathic Personality Inventory (PPI; S. O. Lilienfeld, 1990; S. O. Lilienfeld & B. P. Andrews, 1996) with a community sample has suggested that the PPI subscales may comprise 2 higher order factors (S. D. Benning, C. J. Patrick, B. M. Hicks, D. M. Blonigen, & R. F. Krueger, 2003). However, substantive and structural evidence raises concerns about the viability of this 2-factor model, particularly in offender populations. The authors attempted to replicate the S. D. Benning et al. 2-factor solution using a large (N = 1,224) incarcerated male sample. Confirmatory factor analysis of this model resulted in poor model fit. Similarly, using the same EFA procedures as did S. D. Benning et al., the authors found little evidence for a 2-factor model. When they followed the recommendations of J.-W. van Prooijen and W. A. van der Kloot (2001) for recovering EFA solutions, model fit results provided some evidence that a 3-factor EFA solution could be recovered via confirmatory factor analysis.

Eysenck Personality Questionnaire and Jungian Myers-Briggs type indicator correlation of extraversion-introversion.

Hypothesized that given the methods and content similarity of the Eysenck Personality Questionnaire (EPQ) and the Myers-Briggs Type Indicator (MBTI), the Extraversion-Introversion scales of the inventories will be significantly positively correlated. Data from 93 undergraduates support the prediction and provide a demonstration of convergent validity at the self-report questionnaire level.

Cattell, Comrey, and Eysenck personality factors compared: More evidence for the five robust factors?

We administered the Cattell 16 Personality Factor Questionnaire (16 PF), the Comrey Personality Scales (CPS), and the Eysenck Personality Inventory (EPI) to a sample of 669 Australians that was controlled in composition for age, sex, and social class. Factor analyses derived from analyzing scales of the three inventories in the same matrix produced a group of factors that were similar to the five robust factors of personality found in studies that used ratings by others. Two of the factors were similar to the two EPI scales and five were similar to five of the eight CPS scales. One of these five factors was similar to a single 16PF scale. The 16PF scales were highly overlapping and factorially complex, an indication that fewer than 16 separate constructs are measured at the primary level. There were, however, clear relations between the five factors and the second-order factor structure of the 16PF, as Karson and O'Dell (1976) described.
