"Normal" personality inventories in clinical assessment: General requirements and the potential for using the NEO Personality Inventory.

Issues pertaining to the use of "normal" personality inventories in clinical assessment are discussed. The basic tasks of a clinical evaluation are outlined, and the ability of normal measures of personality such as the NEO Personality Inventory (NEO–PI) to contribute to clinical assessment is considered. The authors conclude that normal personality tests should not be used as stand-alone measures in a clinical evaluation and that currently there is insufficient evidence to support the use of the NEO–PI for the differential diagnosis of psychopathology. The authors note that normal measures of personality show the greatest potential for contribution to clinical assessment in identifying stable personality characteristics.

"'Normal' personality inventories in clinical assessment: General requirements and the potential for using the NEO Personality Inventory": Reply.

Responds to comments by Y. S. Ben-Porath and N. G. Waller (see record 1992-25755-001), noting that (1) no self-report instrument can provide a complete clinical evaluation, but personality measures may contribute to the evaluation; (2) the use of validity scales is controversial and cannot supplant clinical judgment; (3) the NEO Personality Inventory embodies a hierarchical model of personality structure that can aid the interpretation of profiles; (4) anxiety, depression, and impulsiveness (inability to control urges) are all aspects of neuroticism; and (5) the time has come for a systematic reevaluation of all measures used in clinical assessment.

Effects of positive impression management on the NEO Personality Inventory–Revised in a clinical population.

Sixty adults in outpatient psychotherapy completed the NEO Personality Inventory–Revised (NEO PI–R, P. T. Costa & R. R. McCrae, 1992a). Half were instructed to fake good and half were given standard instructions. All completed the Interpersonal Adjective Scale–Revised, Big Five (J. S. Wiggins & P. D. Trapnell, 1997) under standard instructions, and their therapists completed the observer rating form of the NEO Five-Factor Inventory. A comparison group of 30 students completed the NEO PI–R under standard instructions. Standard and fake-good participants obtained significantly different NEO PI–R domain scores. Correlations between the NEO PI–R and criterion measures were significantly lower for faking than for standard patients. Validity scales for the NEO PI–R (J. A. Schinka, B. N. Kinder, & T. Kremer, 1997) were moderately accurate in discriminating faking from standard patients, but were only marginally accurate in discriminating faking patients from students.

Are cross-cultural comparisons of personality profiles meaningful? Differential item and facet functioning in the Revised NEO Personality Inventory.

Measurement invariance is a prerequisite for confident cross-cultural comparisons of personality profiles. Multigroup confirmatory factor analysis was used to detect differential item functioning (DIF) in factor loadings and intercepts for the Revised NEO Personality Inventory (P. T. Costa, Jr., & R. R. McCrae, 1992) in comparisons of college students in the United States (N = 261), Philippines (N = 268), and Mexico (N = 775). About 40%–50% of the items exhibited some form of DIF and item-level noninvariance often carried forward to the facet level at which scores are compared. After excluding DIF items, some facet scales were too short or unreliable for cross-cultural comparisons, and for some other facets, cultural mean differences were reduced or eliminated. The results indicate that considerable caution is warranted in cross-cultural comparisons of personality profiles. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

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. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Personality in adulthood: A six-year longitudinal study of self-reports and spouse ratings on the NEO Personality Inventory.

Previous longitudinal studies of personality in adulthood have been limited in the range of traits examined, have chiefly made use of self-reports, and have frequently included only men. In this study, self-reports (N?=?983) and spouse ratings (N?=?167) were gathered on the NEO Personality Inventory (Costa & McCrae, 1985b), which measures all five of the major dimensions of normal personality. Cross-sectional and longitudinal analyses on data from men and women aged 21 to 96 years showed evidence of small declines in Activity, Positive Emotions, and openness to Actions that might be attributed to maturation, but none of these effects was replicated in sequential analyses. The 20 other scales examined showed no consistent pattern of maturational effects. In contrast, retest stability was quite high for all five dimensions in self-reports and for the three dimensions measured at both times in spouse ratings. Comparable levels of stability were seen for men and women and for younger and older subjects. The data support the position that personality is stable after age 30.

The utility of the Revised NEO Personality Inventory in an outpatient, drug rehabilitation context.

This study evaluated the psychometric properties of the Revised NEO Personality Inventory (NEO–PI–R) in a mostly African American clinical sample and determined if these qualities provided useful information about their motivational characteristics that were germane to treatment. Eighty-two men and 50 women entered a 6-week outpatient drug rehabilitation program, completed the NEO–PI–R, and received counselor ratings of personality at admission. The 99 who finished the program completed a 2nd NEO–PI–R. Counselors provided ratings of treatment responsiveness. The cross-observer, cross-method, cross-time correlations indicated that the NEO–PI–R can be a useful tool for organizing clinical information about clients.

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.

Inferential structure of the NEO Five-Factor Inventory: Construct validity of the Big Four personality clusters.

Four studies investigated the dimensionality of the NEO Five-Factor Inventory (NEO-FFI; P. T. Costa & R. R. McCrae, 1992). In Study 1, four inferential dimensions and four clusters represented the NEO-FFI when 114 undergraduates freely sorted items into categories. Construct validity for four item-clusters derived from the inferential space was obtained in Study 2 based on self-report with 304 undergraduates. Study 3 validated these inferential clusters using self and peer reports for 420 undergraduates. Study 4 validated the cluster scales for predicting quality of life and significant social and cultural behaviours for 110 undergraduates. Implications for implicit personality theory, the number of dimensions issue in personality, and test construction are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The impact of NEO PI-R gender norms on the assessment of personality disorder profiles.

Many personality assessment inventories provide gender-specific norms to allow comparison of an individual's standing relative to others of the same gender. In some cases, this means that an identical raw score produces standardized scores that differ notably depending on whether the respondent is male or female. Thus, an important question is whether unisex-normed scores or gender-normed scores more validly assess personality. Gender-normed and unisex-normed scores from the NEO Personality Inventory—Revised (P. T. Costa & R. R. McCrae, 1992) were examined in a large clinical sample, using 2 measures of personality disorder as validating criteria. Gender-normed scores did not obtain significantly higher correlations. In fact, for 2 personality disorders (antisocial and narcissistic), gender-normed scores yielded significantly lower correlations, suggesting that personality disorder pathology relates most closely to one's absolute level of a personality trait, rather than one's standing relative to others of the same gender. Ramifications of this finding for personality research and clinical assessment are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Multiphasic measurement of child personality: Construction of content scales using the Personality Inventory for Children.

The application of objective test methodology to child personality is seen as having potential for improvement of similar problems in child care or treatment settings such as mental health centers, hospitals, and schools. Intuitive and statistical (internal consistency) procedures were combined to construct 10 scales for measuring child personality: Somatic Concern, poor Family Relations, Asocial Behavior, Aggression, poor Intellectual-Physical Development, Withdrawal, Anxiety, Reality Distortion, Excitement, and poor Social Skills. 4 independently collected samples were used in the construction of the content scales. These samples were designated as clinic (n = 73), psychotic (n = 60), normative (n = 2,386), and general abnormal (n = 198). A 5th sample, normal contrast, was drawn from the normative sample (n = 600). Ss were 5-16 yrs old. The scales were judged to be internally consistent, potentially applicable to clinical decision making, and to require empirical validation.

Positive Impression Management and Its Influence on the Revised NEO Personality Inventory: A Comparison of Analog and Differential Prevalence Group Designs.

Participants (n = 22) completed the Revised NEO Personality Inventory (NEO PI-R) as part of an authentic job application. Protocols produced by this group were compared with "analog" participants (n = 23) who completed the NEO PI-R under standard instructions and again under instructions designed to mimic the test-taking scenario of the job applicants (the "fake-good" condition). Participants completing the NEO PI-R under fake-good instructions and the job applicants scored lower on the Neuroticism and higher on the Extraversion scales than did the participants responding under standard instructions. Analog participants in the fake-good condition scored higher on the Extraversion and lower on the Agreeableness scales than did the job applicants. These results suggest that outcomes from analog designs are generalizable to real-world samples where response dissimulation is probable.

NEO PI-R personality characteristics of high-performing entry-level police officers.

The NEO Personality Inventory-Revised (NEO PI-R; P. T. Costa, Jr., & R. R. McRae, 1992) measures the 5-factor model of personality (Neuroticism, Extraversion, Openness, Agreeableness, Conscientiousness) and 30 specific personality facets within these domains. Researchers in personnel selection are beginning to use the NEO PI-R to describe the personality characteristics of high-functioning employees, including police officers. Here, 100 field training officers (FTOs) described the "best" entry-level police officers they had supervised, using the NEO PI-R Form R (Observer form). The resulting profile was notable for low Neuroticism, high Extraversion, and high Conscientiousness. NEO PI-R profiles of very high- and very low-performing entry-level officers were then compared. The low-performing group had higher Neuroticism and lower Conscientiousness scores than the high-performing group. The latter group was notable for low Neuroticism and high Conscientiousness scores that were similar to those obtained from the FTO sample. Results are relevant to identifying personality characteristics of high-performing entry-level police officers. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Associations among NEO personality assessments and well-being at mid-life: Facet-level analyses.

[Correction Notice: An erratum for this article was reported in Vol 16(1) of Psychology and Aging (see record 2007-17221-001). The article contained an error in the journal title for the Schmutte and Ryff (1997) reference. The correct reference is: Schmutte, P. S., & Ryff, C. D. (1997). Personality and well-being: Reexamining methods and meanings. Journal of Personality and Social Psychology, 73, 549-559.] The association between well-being and personality was examined in 2,379 middle-aged adults. Measures that parallel C. D. Ryff's (1989) psychological model were selected to assess well-being. The 30 facet scales of the NEO-PI–R were used to measure personality. More than 83% of the facet–well-being correlations within the domains of Neuroticism, Extraversion, and Conscientiousness reached statistical significance, whereas, less than half of the correlations within the domains of Agreeableness and Openness were significant. The facets within each domain demonstrated different patterns of associations with the well-being measures, indicating that facet-level assessments yield additional information.

Personality and personality disorders.

Reviews the support for the hypothesis that the personality disorders of the Diagnostic and Statistical Manual of Mental Disorders-III (DSM-III) represent variants of normal personality traits. The focus is, in particular, on the efforts to identify the dimensions of personality that may underlie the personality disorders. The relationship of personality to personality disorders is illustrated using the 5-factor model, conceptual issues in relating normal and abnormal personality traits are discussed, and methodological issues that should be addressed in future research are considered.

The prototype concept in personality assessment.

The concept of the prototype (clear category member) and the fuzzy-set form of cognitive categorization that it entails are useful as an organizational principle for research and assessment in personality psychology. With the aid of a prototype framework for conducting research, personality assessment instruments have been refined, predictable behavioral acts have been brought into focus, abnormal diagnosis has improved, and person perception has been studied. Prototypes work to the extent they provide a better understanding of how people actually think about person variables and behavior. Some of the past payoffs of a prototype approach in the field of personality psychology are reviewed, and a multidimensional scaling model of personality assessment involving a similarity-to-the-prototype rating task is introduced.

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.

Further assessment of the HEXACO Personality Inventory: Two new facet scales and an observer report form.

The HEXACO Personality Inventory (HEXACO-PI) operationalizes the six factors obtained from lexical studies of personality structure in several languages. In this study, psychometric properties of the HEXACO-PI were assessed using a community adult sample and also using observer reports, thereby extending the previous investigation relying only on self-reports from a college student sample. In addition to examining the original 24 HEXACO-PI facet scales, the authors also examined two new facet scales--Altruism versus Antagonism and Negative Self-Evaluation--that assess constructs located interstitially among the factors of the HEXACO space. The HEXACO-PI again showed favorable psychometric properties in terms of reliability and factor structure and also showed high levels of self/observer agreement.

Short-term stability of NEO–PI–R personality trait scores in opioid-dependent outpatients.

The present study examined the short-term stability of personality trait scores from the Revised NEO Personality Inventory (NEO–PI-R) among 230 opioid-dependent outpatients. The NEO–PI-R is a 240-item empirically developed measure of the five-factor model of personality (Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness). Participants completed the NEO–Pl-R at admission and again approximately 19 weeks later. Results indicated fair to good stability for all NEO–PI-R factor domain scores, with coefficients ranging from .68 to .74. Stability of NEO–PI-R scores was decreased among potentially invalid response patterns but was not significantly affected by drug-positive versus drug-negative status at follow-up.

Personality and drunk driving: Identification of DUI types using the Hogan Personality Inventory.

200 persons arrested for driving under the influence (DUI), 30 social drinkers, 30 depressed patients, 30 incarcerated criminals, and 30 alcoholics completed the Hogan Personality Inventory ([HPI]; R. Hogan, 1986) and Court Reporting Network (CRN) interview. A cluster analysis of HPI scores for the DUI group revealed 5 personality types: Impulsive-Extravert, Normal, Neurotic-Introvert, Neurotic-Hostile, and Unassertive-Conformist. The types differed predictably on demographic variables, drinking behavior, and driving records as assessed by the CRN. The Impulsive-Extravert and Normal types had HPI profiles similar to social drinkers. The Neurotic-Introvert type most resembled depressed patients, and the Neurotic-Hostile type most resembled incarcerated criminals. Results clarify previous findings on DUI personality types and establish a basis for tailoring therapeutic treatments to different types of DUI offenders.
