The structure of traits delineating personality disorder in a Chinese sample

The present study examined the factorial structure of a Chinese language version of the self-report Dimensional Assessment of Personality Pathology Questionnaire in 581 adults. Four factors were extracted (Emotional Dysregulation, Dissocial, Inhibition, and Compulsivity) that are similar to the factors extracted in the scales' normative clinical and general population samples from North America (factor comparability coefficients range from .88 to .96), supporting the idea that this trait structure is invariant across diverse populations. The internal consistency of the scales (Cronbach's alpha) was satisfactory across age and gender groups with the exception of the Intimacy Problems scale. Possible explanations for the poor internal consistency of the Intimacy Problems scale, such as cultural differences in social factors influencing marital and romantic relationships in Chinese populations, as opposed to other populations are discussed.     

Dimensional personality traits and the prediction of DSM-IV personality disorder symptom counts in a nonclinical sample

The third edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III; APA, 1980) set forth a categorical system of personality psychopathology that is composed of discrete personality disorders (PDs), each with a distinct set of diagnostic criteria. Although this system is widely accepted and highly influential, alternative dimensional approaches to capturing personality psychopathology have been proposed. Three dimensional models of personality have garnered particular attention-the Five-Factor Model (FFM; Costa & McCrae, 1992), the Seven-Factor Psychobiological Model of Temperament and Character (Seven-Factor Model; Cloninger, Svrakic, & Przybeck, 1993); and the 18-factor model of personality pathology (18-factor model; Livesley, 1986). Although the personality traits from each of these models has been examined in relation to the ten personality disorders in the DSM-IV, no study has examined the comparative and incremental validity of these models in predicting PD symptoms for these ten disorders. Using self-report instruments that measure these models and the ten DSM-IV PDs, correlation and linear regression analyses indicate that traits from all three models had statistically significant associations with PD symptom counts. Hierarchical regressions revealed that the 18-factor model had incremental predictive validity over the FFM and Seven-Fac-tor Model in predicting symptom counts for all ten DSM-IV PDs. The FFM had incremental predictive validity over the Seven-Factor Model model for all ten disorders and the Seven-Factor was able to add incremental predictive validity over the 18-factor model for five of the ten PDs and for eight of the ten disorders relative to the FFM.     

Predicting Psychiatric Symptomatology with the Defense Style Questionnaire-40

The relationship between specific defense styles and symptom-related responses was investigated in a large sample of university students. In general, immature defenses were the major predictors of the symptom patterns measured by the Brief Symptom Inventory. In particular, combinations of projection, displacement, autistic fantasy, somatization, and acting out were the strongest predictors of psychopathology. Projection was a major predictor of psychopathology in males, whereas displacement was the major predictor for females. Several similarities and differences in the relationship between defense styles and different disorders were revealed.;or timing of both psychological and hormonal responses to 2 given volumes of training.     

Gender differences in a clinical sample of patients with borderline personality disorder

The aim of the study was to investigate gender differences and similarities in patients with borderline personality disorder (BPD) with respect to Axis I comorbidity, Axis II comorbidity, general psychopathology (Symptom Checklist 90-Revised), and dimensional personality traits (NEO-Personality-Inventory Revised [NEO-PI-R] and the Dimensional Assessment of Personality Profile Basic questionnaire [DAPP-BQ]). Fifty-seven men and 114 women with BPD were included in the study. Regarding Axis I and II disorders in an exploratory analysis, men with BPD more often fulfilled the diagnostic criteria for binge eating disorder, antisocial personality disorder, narcissistic personality disorder, and conduct disorder in childhood, whereas women had higher frequencies of bulimia nervosa, posttraumatic stress disorder, and panic disorder with agoraphobia. After correcting for multiple tests, only the gender differences in narcissistic and antisocial personality disorder remained significant. In the SCL-90-R profile, no significant gender differences could be identified. In the exploratory analysis of the dimensional personality traits, women showed higher rates on the NEO-PI-R main factors (Neuroticism and Agreeableness) compared to men. In the DAPP-BQ profile, men reached higher sores on the main factor, Dissocial Behavior. When correcting for multiple tests, gender differences still existed for Neuroticism and Dissocial Behavior. Our results argue for gender differences in Axis I and II comorbidity and dimensional personality traits in BPD. However, in general, more similarities than differences were shown in this study.     

Reliability of personality disorder symptoms and personality traits in substance-dependent inpatients

The authors compared the internal consistency, 1-year temporal stability, and self-informant agreement of ratings of personality trait (NEO Five-Factor Inventory; NEO-FFI; P. T. Costa & R. R. McCrae, 1992) and personality disorder symptom severity (Structured Clinical Interview for DSM-III-R Personality Disorders Questionnaire; SCID-II-Q; R. L. Spitzer, J. B. W. Williams, M. Gibbon, & M. First, 1990) in 131 substance-dependent inpatients. Internal consistency coefficients were acceptable to very good for most NEO-FFI and SCID-II-Q scales, and temporal stability correlations were significant for all measures. Agreement between patient and informant ratings was more modest. Substance abuse and depression symptom severity moderated the temporal stability and self-informant agreement of several personality trait and disorder ratings. The authors did not find that the five factors were more reliable than the Axis II symptoms. Issues related to the reliability of personality assessment in multiply diagnosed patients are discussed.     

Assessing the DSM-IV structure of personality disorder with a sample of Chinese psychiatric patients

The validity of the three-cluster system of personality disorders (PDs) in the latest version of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV; APA, 1994) was examined in a sample of Chinese psychiatric patients (n = 227), who completed the self-report Personality Disorders Questionnaire for DSM-IV (PDQ-4; Hyler, 1994) and who were also administered the clinician-rated Personality Disorders Interview-IV (PDI-IV; Widiger, Mangine, Corbit, Ellis, & Thomas,). Using confirmatory factor analysis, a three-factor model corresponding to the DSM-IV clusters was tested and compared statistically to a one-factor model and a set of random, three-factor models. Only the clinician-rated instrument supported the DSM-IV three-cluster model, and then only when the factors were allowed to correlate. Results from the theoretically more rigorous uncorrelated model testing did not support the DSM-IV model for either assessment modality.     

The heterogeneous structure of schizotypal personality disorder: item-level factors of the Schizotypal Personality Questionnaire and their associations with obsessive-compulsive disorder symptoms, dissociative tendencies, and normal personality

A. Raine et al.'s (1994) 3-factor scheme is currently the most widely accepted model of schizotypal personality disorder (SPD). Factor analytic studies of the Schizotypal Personality Questionnaire (SPQ; A. Raine, 1991) subscales, which represent the 9 Diagnostic and Statistical Manual of Mental Disorders (DSM) criteria for SPD, have provided the model's primary support. The use of only 9 modeled variables, however, limits the number of factors that can be extracted. To explicate this structure more fully, the authors conducted item-level factor analyses of the SPQ in a large student sample that completed the instrument twice within a 2-week interval. The authors' analyses failed to support either the 3-factor model of SPD or the 9 existing DSM-based subscales of the SPQ. Instead, 5 replicable dimensions emerged that capture recurrent symptom pairings found in the broader SPD literature: Social Anhedonia, Unusual Beliefs and Experiences, Social Anxiety, Mistrust, and Eccentricity/Oddity. These factors are only weakly correlated with each other and show differential correlational patterns with the Big Five personality traits, dissociative tendencies, and symptoms of obsessive-compulsive disorder. Moreover, they are congruent with dimensional models of personality psychopathology. Implications for SPD in DSM-V are discussed.     

Predicting counterproductive work behavior from the interaction of personality traits

Much attention has been given to enhancing the prediction of counterproductive work behavior (CWB), with a particular focus on the relationship between the five factor model of personality and CWB. Several scholars have advocated for a more complex view of this relationship, and rather than focusing simply on main effects, to examine the interaction of personality traits in predicting employee behavior. In consideration of the traits most strongly related to CWB, we examined the interaction between: (1) conscientiousness and emotional stability, (2) agreeableness and emotional stability, and (3) conscientiousness and agreeableness on CWB directed at individuals (CWB-I) and the organization (CWB-O). Results from a multi-national sample illustrate the interaction of traits increases the prediction of CWB over and above a single trait approach. The interactions suggest employees perform the least CWB when they are high on both traits (in the respective trait pairings), but low levels on either trait relate to increased CWB, and at levels comparable to individuals low on both traits. We conclude research on personality and CWB would benefit from an interactive approach as it allows for greater prediction of CWB-O and CWB-I, which is important in light of the organizational and interpersonal consequences of employee misbehavior.     

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.     

Implicit self- and other-associations in obsessive-compulsive personality disorder traits

This study investigated automatic associations with the self and with others in the context of obsessive-compulsive personality disorder (OCPD). Participants scoring high (n=20) or low (n=20) on DSM-IV OCPD traits performed three irrelevant-feature tasks in which language of the words (Dutch vs. English) was the relevant stimulus feature and word content (OCPD self-view, OCPD other-view, high self-esteem and low self-esteem) the irrelevant feature. Results showed that the high and low OCPD group differed with respect to both explicit and implicit OCPD cognitions. Typically, high OCPD participants showed better performance on OCPD-congruent trials than on OCPD-incongruent trials, whereas low OCPD participants displayed the opposite pattern. This was evident from a semantic Simon effect and from a semantic priming effect. Correlations between direct and indirect measures of OCPD beliefs and of self-esteem were low. Moreover, the indirect OCPD measures contributed uniquely and independently of explicit beliefs to the prediction of OCPD.     

Externalizing pathology and the five-factor model: a meta-analysis of personality traits associated with antisocial personality disorder, substance use disorder, and their co-occurrence

In this meta-analysis we examined Five-Factor Model of personality (FFM) characteristics of externalizing disorders. Two pathologies, Antisocial Personality Disorder (APD) and Substance Use Disorder (SUD), have significant levels of co-occurrence that may be due to shared personality traits. Results from 63 samples (N = 15,331) were analyzed in order to summarize and compare five-factor results for APD, SUD, and co-occurring APD/SUD. Shared and unique personality features were identified at both the domain and the facet level of the FFM. Moderation analyses indicated that sample source (clinical versus community) and diagnosis (psychopathy versus DSM-based APD) accounted for some of the variability at the domain level. Results are discussed with respect to personality and externalizing disorders.     

Psychopathology, childhood trauma, and personality traits in patients with borderline personality disorder and their sisters

The aim of this study was to document and compare adverse childhood experiences, and personality profiles in women with borderline personality disorder (BPD) and their sisters, and to determine how these factors impact current psychopathology. Fifty-six patients with BPD and their sisters were compared on measures assessing psychopathology, personality traits, and childhood adversities. Most sisters showed little evidence of psychopathology. Both groups reported dysfunctional parent-child relationships and a high prevalence of childhood trauma. Subjects with BPD reported experiencing more emotional abuse and intrafamilial sexual abuse, but more similarities than differences between probands and sisters were found. In multilevel analyses, personality traits of affective instability and impulsivity predicted DIB-R scores and SCL-90-R scores, above and beyond trauma. There were few relationships between childhood adversities and other measures of psychopathology. Sensitivity to adverse experiences, as reflected in the development of psychopathology, appears to be influenced by personality trait profiles.     

The meta-contrast technique: relationships with personality traits and cognitive abilities in a healthy male study sample

The relationship between defensive strategies as measured by the Meta-Contrast Technique (MCT) and self-reported trait anxiety, trait aggression and defensiveness, as measured by the Karolinska Scales of Personality (KSP), was investigated in 83 healthy men. Further aims of the study were to describe and document how a healthy and demographically well defined group of subjects responded to the MCT, and to investigate whether age, personality traits and cognitive abilities influenced the reports of picture recognition thresholds in the MCT. The results indicated no agreement between the conceptualization of anxiety as measured by the MCT and anxiety as measured by the KSP inventory. Nor was there any agreement between defensive strategies in the MCT and trait defensiveness as defined with the KSP. However, age, personality traits, and cognitive abilities all contributed to explain the variations in the threshold values of recognition of stimuli pictures, all of which are of central importance in the scoring of MCT protocols.     

Evaluation of the SCID-II personality disorder traits for DSM-IV: coherence, discrimination, relations with general personality traits, and functional impairment

The utility of the DSM personality disorder (PD) system remains a concern. The strategy employed represents one approach designed to evaluate and improve the diagnostic efficiency of the SCID-II PDs. Using a sample of 203 patients, SCID-II PD items-based on the criterion sets of the 10 DSM-IV PDs-were evaluated with respect to (a) convergent validity; (b) divergent validity; (c) relation to general personality traits; and (d) association with functional impairment. Only Borderline PD items were satisfactory on all four evaluation criteria. Histrionic and Obsessive-Compulsive PD items met criteria for convergent and divergent validity and relation to personality dimensions of the Five-Factor Model of Personality (FFM) but were not related to functional impairment, suggesting they might be reconsidered as disorders. Schizotypal PD items met three of the four criteria but showed no relation to FFM dimensions, suggesting that it may be a candidate for reassignment to Axis I.     

Comparing the constructs of antisocial personality disorder and psychopathy in a sample of incarcerated women

Our study examines the relationship between Antisocial Personality Disorder (APD) and psychopathy among a sample of 137 female offenders. Drawing from a historical review of the evolution of these two concepts, we explore their differential relationship to patterns of criminal behavior, psychological adjustment, co-morbidity with other personality disorders, victimization, and institutional adjustment. Findings suggest that the two disorders share a common foundation of social norm violations and deception; however, APD is associated with impulsive, aggressive, and irresponsible behavior, higher rates of childhood abuse, and greater co-morbidity with Cluster A PDs, while psychopathy is better characterized by higher rates of property crimes, previous incarceration, and the manifestation of remorselessness. Results contribute to a further understanding of the etiology and phenomenology of these two disorders and suggest different types of treatment and intervention.     

The relationship between personality traits and psychotic like experiences in a large non-clinical adolescent sample

ObjectiveThe relationship between personality and psychosis is well established. It has been suggested that this relationship may be partly accounted for by higher levels of depression in individuals with certain personality traits. We explored whether the link between personality and psychotic symptoms is already apparent in adolescence, and if this association would still hold when depression was controlled for.Method654 secondary school students were surveyed via self-report questionnaires measuring the Five-Factor model of personality (NEO-FFI), depression (CES-D) and psychotic-like experiences (CAPE).ResultsPositive associations were found between Neuroticism and all CAPE-subscales except Magical Thinking, which was in turn associated with all other personality traits when at high levels. Agreeableness was negatively associated with all CAPE-subscales, while Openness to Experience was only positively associated with Persecutory Ideas and Magical Thinking. After controlling for depression, many of the significant associations remained.ConclusionOur findings suggest that the chance of having psychotic like experiences is more likely for adolescents with certain personality traits. These associations are not fully explained by depression, especially when psychotic experiences are at higher levels. Future research is needed to investigate if these personality traits might put a person at risk for the development of full-blown psychosis.     

Life aspirations,personality traits and subjective well‐being in a Spanish sample

This study examines the relationships between intrinsic/extrinsic aspirations and subjective well‐being (SWB; positive affect, negative affect, satisfaction with life) in a sample of 583 Spanish adults. Firstly, the results showed that high scores for SWB are related to high scores for intrinsic aspirations and, to a lesser extent, to low scores for extrinsic aspirations; it was also found that intrinsic aspirations are mainly related to positive indicators of well‐being, whereas extrinsic aspirations are mainly associated with negative indicators. Secondly, the study also enabled exploration of the links between the domains of the Five‐Factor Model and aspirations; thirdly, the results showed that intrinsic/extrinsic aspirations predict SWB beyond the Five Factors. The results demonstrate the importance of studying the content of human aspirations for understanding psychological health. Copyright © 2011 John Wiley & Sons, Ltd.     

Beliefs in personality disorders: a test with the personality disorder belief questionnaire

The hypothesis that each personality disorder (PD) is characterized by a specific set of beliefs was tested in a sample of 643 subjects, including non-patient controls, axis-I and axis-II patients, diagnosed with SCID-I and -II interviews. Beliefs of six PDs (avoidant, dependent, obsessive-compulsive, paranoid, histrionic, borderline) were assessed with the Personality Disorder Belief Questionnaire (PDBQ). Factor analyses supported the existence of six hypothesized sets of beliefs. Structural equation modeling (SEM) supported the hypothesis that each PD is characterized by a specific set of beliefs. Path coefficients were however in the medium range, suggesting that PDs are not solely determined by beliefs. Nevertheless, empirically derived cutoff scores of the six belief subscales were reasonably successful in classifying subjects, percentages ranging form 51% to 83%. It appeared that there was a monotonical increase in scores on each belief subscale from non-patient controls, to patients without any PD, to patients with PDs (other than the pertinent PD), to patients with the pertinent PD. This suggests that PD-related beliefs are at least partly associated with (personality) psychopathology in general. Another explanation is that many patients' position on the underlying dimensions is not high enough to lead to a DSM PD diagnosis, but high enough to lead to an elevated belief score.     

DAPP-BQ: factor structure and relations to personality disorder symptoms in a non-clinical sample

We assessed the factor structure of the DAPP-BQ (Livesley & Jackson, in press), as well as the relations between DAPP-BQ higher- and lower-order personality trait scores and DSM-IV (APA, 2000) personality disorder symptoms in a sample of approximately 300 nonclinical young adults. The four-factor structure of the DAPP-BQ was replicated, and DAPP-BQ higher-order and lower-order scores were related to personality disorder symptoms in predictable ways. Finally, regression analyses revealed that specific DAPP-BQ traits accounted for variance in individual personality disorder scores above and beyond comorbid personality disorder symptoms.     

Childhood maltreatment and adult personality disorder symptoms in a non‐clinical sample

It can be argued that the well‐substantiated relationship between childhood maltreatment and adult personality disorder (PD) symptoms may be confounded by comorbid symptoms of depression, anxiety or dysfunctional childhood family environments. Therefore, the current study was designed to test the hypothesis that retrospective reports of childhood maltreatment would still be significantly related to reports of more PD symptoms when statistically controlling for these factors. One hundred and seventy‐eight non‐clinical participants were divided into groups reporting childhood maltreatment (n = 54) or not (n = 124) according to scores on the Childhood Trauma Questionnaire. Participants also completed questionnaires measuring current depression, anxiety, and PD symptoms as well as retrospective reports of their childhood environment. Results showed that individuals reporting childhood maltreatment reported more symptoms of PD than those not reporting childhood maltreatment, even when statistically controlling for depression, anxiety and retrospective reports of dysfunctional family environment. These findings underscore the relevance and independent contribution of childhood maltreatment to the development of PDs, with important implications for further research and clinical practice.
