Structural relations between borderline personality disorder features and putative etiological correlates.

This study assessed the structural relations between borderline personality disorder (BPD) features and purported etiological correlates. Approximately 5,000 18-year-old nonclinical young adults were screened for BPD features, and 2 cohorts of participants (total N = 421; approximately one half of whom endorsed significant borderline features) completed the laboratory phase of the study. Measures included self-report and interview-based assessments of BPD psychopathology, personality, psychopathology in biological parents, and childhood physical and sexual abuse. Significant relations between BPD features and purported etiological correlates of BPD were found. A multivariate model that included parental psychopathology, childhood abuse, and personality factors provided an adequate fit to the data and supported the contention that the personality traits disinhibition and negative affectivity underlie BPD features.

A structured interview for the assessment of the Five-Factor Model of personality: facet-level relations to the axis II personality disorders.

The Structured Interview for the Five-Factor Model (SIFFM; Trull & Widiger, 1997) is an 120-item semistructured interview that assesses both adaptive and maladaptive features of the personality traits included in the five-factor model of personality, or "Big Five." In this article, we evaluate the ability of SIFFM scores to predict personality disorder symptomatology in a sample of 232 adults (46 outpatients and 186 nonclinical college students). Personality disorder symptoms were assessed using the Personality Diagnostic Questionnaire-Revised (PDQ-R; Hyler & Rider, 1987). Results indicated that many of the predicted associations between lower-order personality traits and personality disorders were supported. Further, many of these associations held even after controlling for comorbid personality disorder symptoms. These findings may help inform conceptualizations of the personality disorders, as well as etiological theories and treatment.

Relationships of borderline features to parental mental illness, childhood abuse, Axis I disorder, and current functioning.

Although a number of studies have investigated single, putative etiological factors for borderline personality disorder (BPD), few studies have assessed the relations between multiple etiological factors and borderline features within the same study. Borderline features, parental psychopathology, childhood physical and sexual abuse, lifetime Axis I disorder, and current functioning were assessed in 65 nonclinical participants, a portion of which exhibited significant BPD features. Multivariate models were tested and results indicated that parental mental illness and lifetime Axis I disorder were significant and unique predictors of borderline scores. Borderline features accounted for significant variance in current functioning beyond what was accounted for by other predictors; borderline scores mediated the relations between lifetime Axis I disorder and current functioning.

Diagnostic efficiency of the Iowa personality disorder screen items in a nonclinical sample.

The diagnostic efficiency of the 11-item Iowa Personality Disorder Screen (IPDS; Langbehn et al., 1999) was evaluated in a nonclinical sample of young adults, 35% of whom met DSM-III-R criteria for a personality disorder, in a retrospective analysis of SIDP-R data. Results indicated that two IPDS item sets (i.e., combinations of items) produced hit rates of more than 80% along with good sensitivity, specificity, positive predictive power, and negative predictive power. Combined with the findings of Langbehn et al. (1999), these results suggest that the IPDS may be useful as a screening measure for personality disorder in both clinical and nonclinical populations.

The factor structure of the Personality Assessment Inventory-Borderline Features (PAI-BOR) Scale in a nonclinical sample.

We evaluated the fit of Morey's (1991) proposed 4-factor structure on Personality Assessment Inventory-Borderline Features Scale (PAI-BOR; Morey, 1991) items in a sample of approximately 5,000 nonclinical participants. The proposed model did not fit the data well. Results from a series of exploratory and confirmatory factor analyses suggested that a 6-factor model provided the best fit to the PAI-BOR item covariances.

Borderline personality disorder and substance use disorders: a review and integration.

The empirical literature on the comorbidity between borderline personality disorder (BPD) and substance use disorders (SUDs) is reviewed. BPD-SUD comorbidity data obtained from studies published from 1987 to 1997 document the frequent co-occurrence of these diagnoses. Methodological issues and theoretical models for understanding this co-occurrence are discussed. Finally, we present our conceptualization of the relations and interactions of the major factors influencing the development of BPD and contributing to the comorbidity between BPD and SUDs.

Predictors of suggestibility and false-memory production in young adult women.

Recent controversy over memories retrieved in therapy has highlighted the importance of increasing our understanding of individual differences in suggestibility and false-memory production. The purpose of this laboratory study was to assess the ability of several clinically relevant variables (acquiescence, self-esteem, and negative affect) to predict the tendency to yield to suggestive questioning, to alter responses in the face of interpersonal criticism, or to produce false memories (in this study, false recall of implied words). Results indicated that acquiescence significantly predicted suggestibility, as did competence self-esteem scores, but global self-esteem and negative affect scores did not. False-memory production (i.e., false recall of implied words) was associated with higher levels of both acquiescence and negative affect, but the tendency to alter responses after criticism was not significantly predicted by any variable.

Inventory of Interpersonal Problems Personality Disorder scales: operating characteristics and confirmatory factor analysis in nonclinical samples.

Research involving clinical samples has demonstrated the utility of a 28-item personality disorder (PD) screening measure (Inventory of Interpersonal Problems--Personality Disorder scale [IIP-PD]) culled from the IIP in the prediction of the presence or absence of a PD (Pilkonis, Kim, Proietti, & Barkham, 1996). This article extends these diagnostic efficiency findings to nonclinical samples and presents additional data regarding the factor structure of the 28 IIP-PD items. Diagnostic efficiency statistics for the IIP-PD scale, calculated using both interview and self-report methods, support the utility of the IIP-PD scale as a screening tool for the presence or absence of a PD. High specificity estimates indicate that individuals who do not exceed Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994) symptom thresholds rarely exceed the IIP-PD cutoff. Furthermore, a high negative predictive power (NPP) estimate derived using an interview-based diagnostic standard suggests that the IIP-PD scale accurately screens out individuals who do not have a PD. Finally, cross-validated confirmatory factor-analytic results involving items composing the 5 IIP PD subscales identified in previous research (Kim, Pilkonis, & Barkham, 1997) suggest that a measurement model with a single second-order factor (general PD) and 5 first-order factors (one representing each PD subscale) provided the best fit to the observed data compared to 2 other competing models.

Family patterns of perfectionism: an examination of college students and their parents.

We examined patterns of perfectionism among college students and their biological parents in a sample of 188 undergraduates from intact families. Ratings (self vs. other) showed the greatest degree of convergence when daughters were either the target or the rater. Levels of self-oriented perfectionism in students were positively associated with the levels characterizing the same-sex parent, but unrelated (father-daughter) or negatively related (mother-son) to the levels characterizing the opposite-sex parent. Finally, parents' other-oriented perfectionism was not significantly related to students' socially prescribed perfectionism.

Two-year stability of borderline personality measures.

Two-year stability coefficients were computed for several measures of borderline personality disorder within a nonclinical sample (n = 65) that included individuals with significant borderline features. Overall, the stability coefficients were modest (r ranging from .28 to .62; intraclass correlations ranging from .26 to .62). Stability values for each of the self-report measures under study were higher than those for the interview-based measure of BPD features, and, in some cases, these values varied as a function of the prototypicality of the subsamples examined. Analyses conducted to identify moderator effects provided no evidence that the stability of BPD scores was moderated by change in personal distress level; however, changes in BPD self-report scores were related to changes in level of negative affectivity.

Borderline personality disorder features in nonclinical young adults: 2. Two-year outcome.

Borderline personality disorder (BPD) is thought to develop by early adulthood, and it is characterized by lack of control of anger, intense and frequent mood changes, impulsive acts, disturbed interpersonal relationships, and life-threatening behaviors. We describe data from a 2-year follow-up study of nonclinical young adults who, at study entry, exhibited a significant number of BPD features. Individuals with borderline features were more likely to have academic difficulties over the succeeding 2 years, and these participants were more likely to meet lifetime criteria for a mood disorder and to experience interpersonal dysfunction than their peers at the 2-year follow-up assessment. These findings indicate that BPD features are associated with poorer outcome even within a nonclinical population.

Assessment of the five-factor model of personality.

The five-factor model (FFM) of personality is obtaining construct validation, recognition, and practical consideration across a broad domain of fields, including clinical psychology, industrial-organizational psychology, and health psychology. As a result, an array of instruments have been developed and existing instruments are being modified to assess the FFM. In this article, we present an overview and critique of five such instruments (the Goldberg Big Five Markers, the revised NEO Personality Inventory, the Interpersonal Adjective Scales-Big Five, the Personality Psychopathology-Five, and the Hogan Personality Inventory), focusing in particular on their representation of the lexical FFM and their practical application.

Relations of five-factor model antagonism facets with personality disorder symptomatology.

The Five-Factor Model of Personality (FFM) has been used to conceptualize personality disorders as maladaptive variants of normal personality traits. This study assessed the convergence of 6 lower order traits, or facets, of FFM agreeableness versus antagonism (trust, straightforwardness, altruism, compliance, modesty, and tender-mindedness) with antisocial, borderline, narcissistic, paranoid, and passive-aggressive personality traits. Interview-based scores for all of the antagonism facets except compliance demonstrated the expected relations with these personality disorder traits. Results for self-reported facet scores were less clearly supportive, only yielding convergence for straightforwardness and altruism with respect to antisocial traits. It is suggested that future investigations of the FFM, or other normal personality trait models, and personality disorder symptomatology include analyses at the lower order trait level.

Comparison of the big-five factor structure across samples of Chinese and American adults.

We compared the factor structure of Goldberg's (1992) 50-item Bipolar Rating Scale (50-BRS) in samples of Chinese (n = 198) and American (n = 303) students. Results confirmed the hypothesized five-factor pattern for the U.S. sample, and a simultaneous multisample confirmatory factor analysis showed that the same five-factor pattern fit the item covariances in the Chinese sample. High levels of internal consistency were found within each sample, and a high degree of congruency of corresponding item factor loadings was obtained across samples. Overall, results supported the potential utility of the Five-Factor Model and the 50-BRS for assessing personality dimensions in Chinese culture.

Depression and openness to experience.

The relation between depression and Openness to Experience was examined. Self-report measures of personality traits (Revised NEO Personality Inventory; Costa & McCrae, 1992a) and depression (Beck Depression Inventory; Beck, Rush, Shaw, & Emery, 1979; and Inventory to Diagnose Depression; Zimmerman, 1994) were administered to 143 undergraduate participants from the following 3 groups: current depression (n = 46), past depression (n = 50), and never-depressed controls (n = 47). Depressed participants exhibited significantly higher scores than nondepressed controls on two facets of Openness (Aesthetics and Feelings). Openness to Experience was also found to account for a significant proportion of the variance in depression scores, beyond the variance accounted for by Neuroticism and Extraversion. The facet of Openness to Aesthetics appeared to be most strongly related to depression scores, and the facet of Openness to Fantasy was implicated as a moderator of the relation between Extraversion and depression.

Methodological issues in psychopathology research.

We present an overview of methodological issues involved in conducting psychopathology research, including conceptual, analytic, and interpretive considerations. Research issues germane to structured diagnostic interviewed, comorbidity of mental disorders, and ascertainment and sampling are reviewed. Further, the problem of specificity (with respect to disorder, to differential deficit, and to time) is discussed. Specific issues concerning risk vs protective factors, conducting research with special populations, and the continuity of abnormal and normal functioning are highlighted. Finally, various analogue strategies (human subclinical syndromes, experimental study of "pathological" processes in normals, animal models, and computer simulations) are critiqued. Our review documents many of the impressive methodological developments that have emerged in this field, and we hope our review stimulates additional research that exploits recent methodological advances.

Personality, life events, and depression.

The Depressive Experiences Questionnaire (DEQ; Blatt, D'Afflitti, & Quinlan, 1976a) and the Sociotropy-Autonomy Scale (SAS; Beck, Epstein, Harrison, & Emery, 1983) have been used virtually interchangeably to assess personality styles that are believed to influence the development of depressive symptomatology in the context of specific negative life events. This study examined the extent to which these two personality measures overlap and tested the congruency hypothesis. The congruency hypothesis predicts that levels of depression vary as a function of the interaction between personality and the occurrence of thematically related negative life events. Results indicated that the DEQ Dependency and the SAS Sociotropy scales appear to measure similar constructs, whereas the DEQ Self-Criticism and SAS Autonomy scales do not appear to measure similar constructs. Further, support was obtained for the congruency hypothesis using either the DEQ Dependency scale or the SAS Sociotropy scale; however, support for this hypothesis was not obtained for the DEQ Self-Criticism scale or the SAS Autonomy scale.

Personality and disinhibitory psychopathology: alcoholism and antisocial personality disorder.

We discuss the relation between personality factors and two adult forms of disinhibitory psychopathology--alcohol abuse or dependence and antisocial personality disorder. First, we briefly review various methodological issues relevant to research in this area. Next, we review empirical findings relating three broad-band personality trait dimensions neuroticism/emotionality, impulsivity/disinhibition, extraversion/sociability) to both alcohol abuse and dependence and antisocial personality disorder. Finally, theoretical models of the relationship between personality and each of these two disorders are presented. We conclude that although no single personality description is likely to be both a sensitive and specific indicator of either alcoholism or antisocial personality disorder, personality variables are important components of etiological models of these disorders.
