A comparison of the validity of the Five-Factor Model (FFM) Personality Disorder Prototypes using FFM self-report and interview measures.

Recent studies have demonstrated that personality disorders (PDs) can be assessed via a prototype-matching technique, which enables researchers and clinicians to match an individual's five-factor model (FFM) personality profile to an expert-generated prototype. The current study examined the relations between these prototype scores, using interview and self-report data, and PD symptoms in an outpatient sample (N = 115). Both sets of PD prototype scores demonstrated significant convergent validity with PD symptom counts, suggesting that the FFM PD prototype scores are appropriate for use with both sources of data.

Using a Five-Factor Lens to Explore the Relation Between Personality Traits and Violence in Psychiatric Patients.

Recent work suggests that predictors of violence are similar for individuals with and without mental illness. Although psychopathy is among the most potent of such predictors, the nature of its relation to violence is unclear. On the basis of a sample of 769 civil psychiatric patients, the authors explore the possibility that measures of psychopathy provide a glimpse of higher order personality traits that predispose individuals toward violence. Results indicate that general traits captured by a measure of the 5-factor model, particularly antagonism, were relatively strongly associated with violence and shared most of their violence-relevant variance with a leading measure of psychopathy. Because interpersonal and affective features of psychopathy are less important than basic traits of antagonism in postdicting violence, it may be appropriate to broaden focus in risk assessment to patients' basic personality traits.

The Representation of Four Personality Disorders by the Schedule for Nonadaptive and Adaptive Personality Dimensional Model of Personality.

This study examined the relationships of the Schedule for Nonadaptive and Adaptive Personality (SNAP) model of personality to 4 targeted personality disorders (PDs) in a large multisite sample of patients. Data were examined from 529 patients, who were assigned 1 of 5 primary diagnoses: borderline, schizotypal, avoidant, and obsessive-compulsive PDs and major depression without PD. Patients were administered the SNAP questionnaire and results were compared among diagnostic groups and between patient groups and nonclinical norms. Results indicated that the dimensions of the model appear to have considerable promise in differentiating normal from abnormal personality, particularly in the propensity of individuals with PDs to manifest negative affects and interpersonal detachment. Furthermore, the model appeared to successfully distinguish specific PDs, a property that represents a particular challenge for dimensional models of personality.

Associations in the Course of Personality Disorders and Axis I Disorders Over Time.

In this study, the authors examined time-varying associations between schizotypal (STPD), borderline (BPD), avoidant (AVPD), or obsessive-compulsive (OCPD) personality disorders and co-occurring Axis I disorders in 544 adult participants from the Collaborative Longitudinal Personality Disorders Study. The authors tested predictions of specific longitudinal associations derived from a model of crosscutting psychobiological dimensions (L. J. Siever & K. L. Davis, 1991) with participants with the relevant Axis I disorders. The authors assessed participants at baseline and at 6-, 12-, and 24-month follow-up evaluations. BPD showed significant longitudinal associations with major depressive disorder and posttraumatic stress disorder. AVPD was significantly associated with anxiety disorders (specifically social phobia and obsessive-compulsive disorder). Two of the four personality disorders under examination (STPD and OCPD) showed little or no association with Axis I disorders. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Review of Personality disorders and the Five-Factor Model of personality.

Reviews the book, Personality disorders and the Five-Factor Model of personality, edited by Paul T. Costa Jr. and Thomas A. Widiger (see record 1993-99107-000). This book's value lies in its comprehensive coverage of the links between a particular model of personality dispositions and a wide range of topics relating to personality dysfunctions and disorders. The particular model of personality dispositions is the Five-Factor Model (FFM) developed by Costa and McCrae, and with the exception of a chapter by Millon buried near the end of the book all of the authors explicitly use the FFM as a conceptual framework. The book begins with an introduction by the editors, followed by three chapters of Conceptual Background. Part II includes four chapters of Empirical Research. These first seven chapters will be of interest to scientists interested in personality and psychopathology. The final four chapters, however, are not well integrated with the rest, and thus seem superfluous and out of place. All in all, though, clinicians will find many chapters to mull over, and both scientists and clinicians will applaud the book's value as a resource in the understanding of personality disorders.

Factor Structure of the Psychopathic Personality Inventory: Validity and Implications for Clinical Assessment.

Psychopathy is a personality disorder characterized by impulsive antisocial deviance in the context of emotional and interpersonal detachment. A factor analysis of the subscales of the Psychopathic Personality Inventory (PPI) yielded evidence for 2 factors. One factor showed relations with external criteria mirroring those of the emotional-interpersonal facet of psychopathy, including high dominance, low anxiety, and venruresomeness. The other factor showed relations paralleling those of the social deviance facet of psychopathy, including positive correlations with antisocial behavior and substance abuse, negative correlations with socioeconomic status and verbal ability, and personality characteristics including high negative emotionally and low behavioral constraint. Findings support using the PPI to assess these facets of psychopathy in community samples and to explore their behavioral correlates and genetic-neurobiological underpinnings.

The Longitudinal Relationship of Personality Traits and Disorders.

Personality disorders are presumed to be stable because of underlying stable and maladaptive personality traits, but while previous research has demonstrated a link between personality traits and personality disorders cross-sectionally, personality disorders and personality traits have not been linked longitudinally. This study explores the extent to which relevant personality traits are stable in individuals diagnosed with 4 personality disorders (schizotypal, borderline, avoidant, and obsessive-compulsive personality disorders) and examines the assumption that these personality disorders are stable by virtue of stable personality traits. This assumption was tested via the estimation of a series of latent longitudinal models that evaluated whether changes in relevant personality traits lead to subsequent changes in personality disorders. In addition to offering large consistency estimates for personality traits and personality disorders, the results demonstrate significant cross-lagged relationships between trait change and later disorder change for 3 of the 4 personality disorders studied.

Alcohol, Tobacco, and Drug Use Disorders and Personality Disorder Symptoms.

In a nonclinical sample of 395 young adults, the authors evaluated the relations between major personality traits, Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV; American Psychiatric Association, 1994) personality disorder symptoms, and DSM-IV alcohol use disorders (AUDs). Consistent with previous findings, traits related to disinhibition and negative affectivity were consistently associated with AUDs, as were Cluster B personality disorder symptoms (especially antisocial and borderline disorder symptoms). Multivariate analyses revealed that Cluster B symptoms were significantly associated with AUDs above and beyond what was accounted for by personality traits. Further, the authors found differential patterns of relations between other substance use disorders (SUDs; i.e., tobacco dependence and drug use diagnoses) and personality disorder symptoms. Overall, these results suggest that personality disorder symptoms predict unique variance in SUDs that reflect maladaptive aspects of personality traits.

Borderline personality disorder from the perspective of general personality functioning.

The authors extended previous work on the hypothesis that borderline personality disorder (BPD) can be understood as a maladaptive variant of personality traits included within the 5-factor model (FFM) of personality. In each of 3 samples, an empirically derived prototypic FFM borderline profile was correlated with individuals' FFM profiles to yield a similarity score, an FFM borderline index. Results across all samples indicated that the FFM borderline index correlated as highly with existing borderline measures as they correlated with one another, and the FFM borderline index correlated as highly with measures of dysfunction, history of childhood abuse, and parental psychopathology as did traditional measures of BPD. Findings support the hypothesis that BPD is a maladaptive variant of FFM personality traits. (PsycINFO Database Record (c) 2010 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)     

Circumplex structure and personality disorder correlates of the Interpersonal Problems Model (IIP-C): Construct validity and clinical implications.

This study assessed the construct validity of the circumplex model of the Inventory of Interpersonal Problems (IIP-C) in Norwegian clinical and nonclinical samples. Structure was examined by evaluating the fit of the circumplex model to data obtained by the IIP-C. Observer-rated personality disorder criteria (DSM-IV, Axis II) were used as external correlates. The reliability of the IIP-C scales was acceptable and in the same range as in the original version. A multisample analysis strategy did not support an invariant circumplex model across the 2 groups. However, the estimated structures reflected mostly the same circular pattern of a quasi-circumplex model in the 2 groups. Departures from the ideal model were of negligible practical significance. The validity results examining personality disorder correlates of the IIP-C generally conformed to predictions, providing direct evidence for agreement between self-report and expert judgments of interpersonal problems.

Unsupported Gender Differences on Some Personality Disorder Scales of the Millon Clinical Multiaxial Inventory-III.

Psychologists in many settings work with clients who may have personality disorders, and psychologists need to identify such problems accurately and fairly. The Millon Clinical Multiaxial Inventory-III focuses on attempting to diagnose personality disorders, but a number of its scales manifest gender differences that are not supported by research data. Practitioners should be very cautious about using this measure and be aware that, in some cases, a focus on assessment of relevant patterns of emotion and behavior is preferable to trying to diagnose whether a personality disorder is present.

Five-factor model personality disorder prototypes in a community sample: Self- and informant-reports predicting interview-based DSM diagnoses.

The need for an empirically validated, dimensional system of personality disorders is becoming increasingly apparent. While a number of systems have been investigated in this regard, the five-factor model of personality has demonstrated the ability to adequately capture personality pathology. In particular, the personality disorder prototypes developed by Lynam and Widiger (2001) have been tested in a number of samples. The goal of the present study is to extend this literature by validating the prototypes in a large, representative community sample of later middle-aged adults using both self and informant reports. We found that the prototypes largely work well in this age group. Schizoid, Borderline, Histrionic, Narcissistic, and Avoidant personality disorders demonstrate good convergent validity, with a particularly strong pattern of discriminant validity for the latter four. Informant-reported prototypes show similar patterns to self reports for all analyses. This demonstrates that informants are not succumbing to halo representations of the participants, but are rather describing participants in nuanced ways. It is important that informant reports add significant predictive validity for Schizoid, Antisocial, Borderline, Histrionic, and Narcissistic personality disorders. Implications of our results and directions for future research are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Incremental Validity of the Frame-of-Reference Effect in Personality Scale Scores: A Replication and Extension.

Context-specific personality items provide respondents with a common frame of reference unlike more traditional, noncontextual personality items. The common frame of reference standardizes item interpretation and has been shown to reduce measurement error while increasing validity in comparison to noncontextual items (M. J. Schmit, A. M. Ryan. S. L. Stierwalt. & S. L. Powell, 1995). Although the frame-of-reference effect on personality scales scores has been well investigated (e.g., M. J. Schmit et al., 1995), the ability of this innovation to obtain incremental validity above and beyond the well-established, noncontextual personality scale scores has yet to be examined. The current study replicates and extends work by M. J. Schmit et al. (1995) to determine the incremental validity of the frame-of-reference effect. The results indicate that context-specific personality items do indeed obtain incremental validity above and beyond both noncontextual items and cognitive ability, and in spite of socially desirable responding induced by applicant instructions. The implications of these findings for personnel selection are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

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)     

A structured interview for the assessment of the Five-Factor Model of Personality.

The authors report on the psychometric properties of a new semistructured interview, the Structured Interview for the Five-Factor Model of Personality (SIFFM; T J. Rull & T A. Widiger, 1997). The SIFFM assesses major dimensions of the five-factor model (FFM) as well as trait facets for each dimension. Analyses of data obtained from both nonclinical and clinical participants support the reliability and validity of SIFFM scores. Specifically, SIFFM scores were reliable across raters, were internally consistent and relatively stable over time, and were correlated with scores from related measures (e.g., personality, personality disorders). The authors discuss the need for and attractiveness of an interview-based measure of the FFM in assessing normal and dysfunctional personality traits.

Assessing Personality With a Structured Employment Interview: Construct-Related Validity and Susceptibility to Response Inflation.

The authors evaluated the extent to which a personality-based structured interview was susceptible to response inflation. Interview questions were developed to measure facets of agreeableness, conscientiousness, and emotional stability. Interviewers administered mock interviews to participants instructed to respond honestly or like a job applicant. Interviewees completed scales of the same 3 facets from the NEO Personality Inventory, under the same honest and applicant-like instructions. Interviewers also evaluated interviewee personality with the NEO. Multitrait-multimethod analysis and confirmatory factor analysis provided some evidence for the construct-related validity of the personality interviews. As for response inflation, analyses revealed that the scores from the applicant-like condition were significantly more elevated (relative to honest condition scores) for self-report personality ratings than for interviewer personality ratings. In addition, instructions to respond like an applicant appeared to have a detrimental effect on the structure of the self-report and interview ratings, but not interviewer NEO ratings.
