Active versus reactive cooperativeness in Borderline Psychopathology: A dissection based on the HEXACO model of personality

The concept of personality disorders (PDs) is shifting from categorical to dimensional, conceptualizing PDs as maladaptive variants of basic personality traits. The Agreeableness trait in the Five Factor Model of personality classically represents dispositional cooperativeness, which is associated with PDs characterized by interpersonal impairments. However, recent research designates two separate dispositional tendencies: active and reactive cooperativeness. Using the HEXACO model of personality we assessed traits representing these tendencies (Honesty–Humility and Agreeableness) and investigated their relation to Borderline features in 602 individuals. Borderline features were associated with low Agreeableness scores, representing low reactive cooperation, entailing a tendency to retaliate. Yet, there was no association with Honesty–Humility, implying intact active cooperativeness and non-exploitation. These findings extend prior results on the relation between Borderline PD and basic personality dimensions driving prosocial behavior. Implications for the understanding of interpersonal problems in PDs and the refinement of existing therapies are discussed.

Childhood adversity in association with personality disorder dimensions: New findings in an old debate

BackgroundVarious studies have reported a positive relationship between child maltreatment and personality disorders (PDs). However, few studies included all DSM-IV PDs and even fewer adjusted for other forms of childhood adversity, e.g. bullying or family problems. MethodWe analyzed questionnaires completed by 512 participants of the ZInEP epidemiology survey, a comprehensive psychiatric survey of the general population in Zurich, Switzerland. Associations between childhood adversity and PDs were analyzed bivariately via simple regression analyses and multivariately via multiple path analysis. ResultsThe bivariate analyses revealed that all PD dimensions were significantly related to various forms of family and school problems as well as child abuse. In contrast, according to the multivariate analysis only school problems and emotional abuse were associated with various PDs. Poverty was uniquely associated with schizotypal PD, conflicts with parents with obsessive-compulsive PD, physical abuse with antisocial PD, and physical neglect with narcissistic PD. Sexual abuse was statistically significantly associated with schizotypal and borderline PD, but corresponding effect sizes were small. ConclusionChildhood adversity has a serious impact on PDs. Bullying and violence in schools and emotional abuse appear to be more salient markers of general personality pathology than other forms of childhood adversity. Associations with sexual abuse were negligible when adjusted for other forms of adversity.

Can protective factors moderate the detrimental effects of child maltreatment on personality functioning?

ObjectiveThe aim of this study was to examine whether, and if so, to what extent, education and coping strategies may reduce the detrimental effects of childhood maltreatment on personality functioning. MethodsWe assessed dimensional trait-scores of all 10 DSM-IV personality disorders (PDs), childhood maltreatment, education and three coping styles in 511 subjects of the general population of Zurich, Switzerland, using data from the ZInEP Epidemiology Survey. ResultsChildhood maltreatment was associated with all 10 PDs. Low education was related to antisocial, borderline and histrionic PD. Low emotion-focused coping was associated with paranoid, schizoid, borderline, avoidant, and obsessive–compulsive PD. Low problem-focused coping was related to schizoid PD and high problem-focused coping to histrionic PD. High dysfunctional coping was significantly related to all 10 PD dimensions. Obsessive–compulsive trait scores were significantly lower in maltreated subjects with high emotion-focused coping. Antisocial, borderline and narcissistic trait scores were significantly higher in maltreated subjects with high dysfunctional coping. ConclusionEducation and adaptive coping may have a protective effect on PD symptomatology. Promotion of adaptive coping and suppression of dysfunctional coping may additionally reduce PD symptoms specifically in maltreated subjects. Those findings have important clinical implications. Longitudinal research is needed to address questions of causality and to evaluate potential effects of treatment and intervention.

Interpersonal functioning deficits in association with DSM-IV personality disorder dimensions

According to DSM, interpersonal functioning deficits are a main criterion for the general definition of personality disorders (PDs), but some PD diagnoses do not appear to be related to impaired interpersonal functioning. Social deficits have rarely been studied in all PD dimensions to date. We analyzed 511 adults aged 20-41 years from the general population of the canton of Zurich, Switzerland, using data from the Epidemiology Survey of the Zurich Programme for Sustainable Development of Mental Health Services (ZInEP). PD dimensions were measured with a questionnaire and indicators of interpersonal functioning with a semi-structured interview. Associations were analyzed with generalized linear models. All PD dimensions were significantly associated with various indicators of interpersonal functioning deficits, such as distress and conflicts in friendships and partnership, feeling lonely, few close friends, and reduced social support. Schizotypal and borderline PD were relatively strongly associated with distress in friendships when compared with other PD dimensions. Furthermore, both dimensions were significantly related to all indicators of interpersonal functioning deficits. Subjects scoring high on any PD dimension reported considerable deficits in interpersonal functioning as characterized by a solitary lifestyle, conflictual and distressful social relations, and lack of social support. All DSM-IV PDs are associated with poor interpersonal functioning, but there is some evidence that schizotypal and borderline symptomatology affects deficits in social interactions even more profoundly and pervasively than other PD dimensions.

Is Dimensional Scoring of Borderline Personality Disorder Important Only for Subthreshold Levels of Severity?

Studies comparing dimensional and categorical representations of personality disorders (PDs) have consistently found that PD dimensions are more reliable and valid. While comparisons of dimensional and categorical scoring approaches have consistently favored the dimension model, two reports from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project have raised questions as to when dimensional scoring is important. In the first study, Asnaani, Chelminski, Young, and Zimmerman (2007) found that once the diagnostic threshold for borderline PD was reached the number of criteria met was not significantly associated with indices of psychosocial morbidity. In the second study, Zimmerman, Chelminski, Young, Dalrymple, and Martinez (2012) found that patients with 1 criterion of borderline PD had significantly more psychosocial morbidity than patients with 0 criteria. The findings of these two studies suggest that dimensional ratings of borderline PD may be more strongly associated with indicators of illness severity for patients who do not versus do meet the DSM-IV criteria for borderline PD. In this third report from the MIDAS project, we tested this hypothesis in a study of 3,069 psychiatric outpatients evaluated with semi-structured diagnostic interviews. In the patients without borderline PD the number of borderline features was significantly associated with each of 6 indicators of illness severity, whereas in the patients with borderline PD 3 of the 6 correlations were significant. The mean correlation between the number of borderline PD criteria and the indicators of illness severity was nearly three times higher in the patients without borderline PD than the patients with borderline PD (0.23 versus 0.08), and 4 of the 6 correlation coefficients were significantly higher in the patients without borderline PD. These findings suggest that dimensional scoring of borderline PD is more important for subthreshold levels of pathology and are less critical once a patient meets the diagnostic threshold. The implications of these findings for DSM-5 are discussed.

Have Personality Disorders Been Overdiagnosed among Eating Disorder Patients?

Background: There is persuasive evidence for a relationship between eating disorders (EDs) and personality disorders (PDs). Research studies over the last three decades have used various tools to explore PDs in EDs with differing results. We investigated PDs derived from an interview - the International Personality Disorder Examination. Methods: 132 female inpatients with restrictive anorexia nervosa (AN-R), binge-purging AN, bulimia nervosa (BN) and ED not otherwise specified were interviewed. MANCOVA was used to test for differences in dimensional PD scores for the ED diagnostic and behavioural groups. Results: Twenty-one percent of patients had a definite DSM-IV PD diagnosis and 37% of patients had ≥1 definite or probable DSM-IV PD diagnoses. Cluster C PDs were most commonly found [avoidant (25%), obsessive-compulsive (9%), dependent (2%)], followed by cluster B PDs [borderline (13%), histrionic (2%)]. Comparison of PD dimensional scores revealed significantly lower PD scores for borderline PD in AN-R when compared to the other diagnostic groups; and significantly higher scores for histrionic, narcissistic, antisocial, and not otherwise specified PDs for BN when compared to the other diagnostic groups. Self-induced vomiting was the only behaviour significantly associated with any PD dimensional scores (borderline and narcissistic). Conclusions: Assessment of PDs using a highly structured interview administered by trained interviewers results in less PD diagnoses compared with previous studies of inpatients with an ED. Avoidance is the most common PD and those patients who induce vomiting are more likely to have borderline features.

Ten‐Year Rank‐Order Stability of Personality Traits and Disorders in a Clinical Sample

This study compares the 10-year retest stability of normal traits, pathological traits, and personality disorder dimensions in a clinical sample. Ten-year rank-order stability estimates for the Revised NEO Personality Inventory, Schedule for Nonadaptive and Adaptive Personality, and Diagnostic Interview for DSM-IV Personality Disorders were evaluated before and after correcting for test-retest dependability and internal consistency in a clinical sample (N = 266). Dependability-corrected stability estimates were generally in the range of.60-.90 for traits and.25-.65 for personality disorders. The relatively lower stability of personality disorder symptoms may indicate important differences between pathological behaviors and relatively more stable self-attributed traits and imply that a full understanding of personality and personality pathology needs to take both traits and symptoms into account. The five-factor theory distinction between basic tendencies and characteristic adaptations provides a theoretical framework for the separation of traits and disorders in terms of stability in which traits reflect basic tendencies that are stable and pervasive across situations, whereas personality disorder symptoms reflect characteristic maladaptations that are a function of both basic tendencies and environmental dynamics.

Subtypes, Dimensions, Levels, and Mental States in Narcissism and Narcissistic Personality Disorder

Various conceptualizations of subtypes, levels, and dimensions of narcissism and narcissistic personality disorder (NPD) are considered with a particular focus on overt grandiose presentations and covert vulnerable presentations. Evidence supporting this distinction and clinical vignettes to illustrate it are presented as well as their implications for clinical work with NPD patients. The research and clinical evidence points to the conclusion that these broad categorical subtypes are better conceptualized as dimensions on which individual patients vary on relative levels, thus suggesting that grandiose and vulnerable presentations represent two sides of the same coin. A case example and clinical implications are provided and discussed.

Neurocognitive Deficits in Borderline Personality Disorder: Implications for Treatment

The cognitive dimension of Borderline Personality Disorder has received relatively little attention in the clinical literature and is poorly understood. This article illustrates how a range of cognitive problems including attention deficit disorder and learning disabilities may contribute to the cognitive disturbances identified in the disorder including dissociation, paranoia, all or nothing thinking, overvalued ideas, and denial and splitting. A review of relevant research supporting the presence of cognitive deficits is summarized along with a developmental pathway for the expression of the cognitive dimension. Clinical examples are provided. Recommendations for inclusion of assessment and treatment strategies that address cognitive deficits within a psychodynamically based psychotherapy are discussed.

Relationship between personality disorder dimensions and verbal memory functioning in a community population

Based on the Baltimore Epidemiologic Catchment Area (ECA) follow-up survey, we examined relationships between dimensions of Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) personality disorders and both subjective and objective memory functioning in a community population. Our study subjects consisted of 736 individuals from the ECA follow-up study of the original Baltimore ECA cohort, conducted between 1993 and 1996 and available for assessment in the Hopkins Epidemiology Study of Personality Disorders from 1997 to 1999. Subjects were assessed for DSM-IV personality disorders using a semi-structured instrument, the International Personality Disorder Examination, and were asked about a subjective appraisal of memory. Verbal memory function, including immediate recall, delayed recall, and recognition, were also evaluated. Multiple linear regression analyses were used to determine associations between personality dimensions of DSM-IV Axis II traits and subjective and objective memory functioning. Scores on schizoid and schizotypal personality dimensions were associated with subjective and objective memory dysfunction, both with and without adjustment for Axis I disorders. Borderline, antisocial, avoidant, and dependent personality disorder scores were associated with subjective memory impairment only, both with and without adjustment for Axis I disorders. This study suggests that subjective feelings of memory impairment and/or objective memory dysfunction are associated with specific personality disorder dimensions.

The Shedler-Westen Assessment Procedure (SWAP)

The Shedler-Westen assessment procedure (SWAP) is a personality assessment instrument designed for use by expert clinical assessors. Critics have raised questions about its psychometrics, most notably its validity across observers and situations, the impact of its fixed score distribution on research findings, and its test-retest reliability. We review empirical data addressing its validity, emphasizing the multitrait-multimethod approach to evaluating test validity. To evaluate the hypothesis that the fixed, asymmetric score distribution artifactually inflates correlations between SWAP profiles, we conducted Monte Carlo simulations and also presented empirical data from a large patient sample. We observed a mean correlation of zero between simulated SWAP profiles, indicating that the score distribution does not impact the correlation coefficients. Empirical correlations between SWAP profiles of actual patients were small and similar to those obtained using Diagnostic and statistical manual of mental disorders, fourth edition (DSM-IV) personality disorder scales that had no fixed score distributions, suggesting that the correlations were not a methodological artifact of the SWAP. We report new test-retest reliability data (median coefficient > .85) for the SWAP's trait and personality disorder dimensions. The SWAP appears to be reliable and valid. The data do not support its primary psychometric critiques.

Distinguishing general and specific personality disorder features and implications for substance dependence comorbidity.

Clinical and population-based samples show high comorbidity between Substance Use Disorders (SUDs) and Axis II Personality Disorders (PDs). However, Axis II disorders are frequently comorbid with each other, and existing research has generally failed to distinguish the extent to which SUD/PD comorbidity is general or specific with respect to both specific types of PDs and specific types of SUDs. We sought to determine whether ostensibly specific comorbid substance dependence-Axis II diagnoses (e.g., alcohol use dependence and borderline personality disorder) are reflective of more pervasive or general personality pathology or whether the comorbidity is specific to individual PDs. Face-to-face interview data from Wave 1 and Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions were analyzed. Participants included 34,653 adults living in households in the United States. We used hierarchical factor models to statistically partition general and specific personality disorder dimensions while simultaneously testing for specific PD-substance dependence relations. Results indicated that substance dependence-Axis II comorbidity is characterized by general (pervasive) pathology and by Cluster B PD pathology over and above the relationship to the general PD factor. Further, these relations between PD factors and substance dependence diagnoses appeared to largely account for the comorbidity among substance dependence diagnoses in the younger but not older participants. Our findings suggest that a failure to consider the general PD factor, which we interpret as reflecting interpersonal dysfunction, can lead to potential mischaracterizations of the nature of certain PD and SUD comorbidities.

Toward a Multidimensional Model of Personality Disorder Diagnosis: Implications for DSM–5

This article outlines a model of personality disorder (PD) diagnosis that combines clinically useful constructs from the Diagnostic and Statistical Manual of Mental Disorders (DSM) with assessment procedures that maximize reliability and clinical utility while minimizing problems associated with threshold-based PD classification. I begin by addressing limitations in the current DSM conceptualization of PDs: excessive comorbidity, use of arbitrary cutoffs to distinguish normal from pathological functioning, failure to capture variations in the adaptive value of PD symptoms, and inattention to situational influences that shape PD-related behaviors. The revisions proposed by the DSM–5 Personality and Personality Disorders Work Group help resolve some of these issues, but create new problems in other areas. A better solution would be to employ a multidimensional model of PD diagnosis in which clinicians (a) assign a single dimensional rating of overall level of personality dysfunction, (b) provide separate intensity and impairment ratings for each PD dimension, and (c) list those personality traits—including PD-related traits—that enhance adaptation and functioning. Preliminary evidence bearing on the multidimensional model is reviewed, and broader clinical and empirical implications of the model are discussed.

Beyond Dysfunction and Threshold-Based Classification: A Multidimensional Model of Personality Disorder Diagnosis

An alternative dimensional model of personality disorder (PD) diagnosis that addresses several difficulties inherent in the current DSM conceptualization of PDs (excessive PD overlap and comorbidity, use of arbitrary thresholds to distinguish normal from pathological personality functioning, failure to capture variations in the adaptative value of PD symptoms, and inattention to the impact of situational influences on PD-related behaviors) is outlined. The model uses a set of diagnostician-friendly strategies to render PD diagnosis in three steps: (1) the diagnostician assigns every patient a single dimensional rating of overall level of personality dysfunction on a 50-point continuum; (2) the diagnostician assigns separate intensity and impairment ratings for each PD dimension (e.g., narcissism, avoidance, dependency); and (3) the diagnostician lists any personality traits-including PD-related traits-that enhance adaptation and functioning (e.g., histrionic theatricality, obsessive attention to detail). Advantages of the proposed model for clinicians and clinical researchers are discussed.

What Attracts Men Who Batter to Their Partners? An Exploratory Study

Men who batter, because of particular personality traits and sense of entitlement, may select partners whom they perceive will be dependent on them, meet their emotional needs, or be "objects" of physical attractiveness. During treatment intake, 181 offenders responded to the question, "What attracted you to her (your partner)?" We explored whether men who mentioned their own needs or her physical traits would engage in more frequent and severe violence and would have specific forms of personality disorder dimensions or personality traits. Six categories of attraction, including "her physical traits" and "his needs," were derived from the men's responses. The results showed that men who focused on their partners' physical attractiveness were more likely to be violent after treatment. Men who cited their own needs for their attraction had higher scores on borderline personality, alcohol abuse, and psychotic thinking and lower scores on compulsive-conforming.

Borderline personality disorder traits and their relationship with dimensions of normative personality: a web-based cohort and twin study

To describe the structure of genetic and environmental risk factors for four dimensions of borderline personality disorder (BPD) and to understand the source of resemblance of these dimensions and normal personality. A web-based sample (n = 44,112 including 542 twin pairs) completed items from 4 scales of the Dimensional Assessment of Personality Pathology Basic Questionnaire and the Big Five Inventory. A one-factor common pathway model best fits the 4 BPD scales producing a highly heritable latent liability (heritability = 60%) and strong loadings on all 4 dimensions. Affective instability had the lowest trait-specific genetic loading, suggesting that it was a core feature of BPD. A complex pattern of genetic and environmental associations was found between the big five personality traits and BPD dimensions. The strongest genetic correlations with the BPD traits were generally seen for neuroticism (positive), followed by conscientiousness and agreeableness, both negative. In the general population, these four BPD dimensions reflect one underlying highly heritable factor. The association between normative personality and dimensions of BPD is complex with high degrees of genetic correlation.

Personality Disorders and Clinical Syndromes in ADHD Prisoners

Objective: The main objective of this article is to investigate the type of personality disorders and clinical syndromes (CSs) that were best related to ADHD symptoms among prisoners. Method: The authors screened for childhood and adult ADHD symptoms and administered the Millon Clinical Multiaxial Inventory–III (MCMI-III) to 196 serving prisoners. Results: Childhood and adult ADHD symptoms were most strongly related to the compulsive (negative relationship) and borderline (positive relationship) scales on the MCMI-III with large and medium effect sizes, respectively. Hierarchical multiple regressions revealed that the absence of compulsive personality disorder traits (i.e., a low score as a dimension) was the single best Axis II predictor of childhood and adult ADHD symptoms. CSs did not add significantly to the variance in childhood ADHD beyond that of the personality disorder dimensions, but it did so for current ADHD symptoms in relation to alcohol dependence. Conclusion: The findings demonstrate the relative absence of compulsive personality disorder traits in prisoners with ADHD symptoms as core maladaptive traits involving disorganization.

Relationship between Assessed Emotion, Personality, Personality Disorder and Risk in Offenders with Intellectual Disability

In mainstream studies on offenders and on individuals with psychopathology, relationships have been found between personality characteristics, emotional problems and personality disorders. This study reviewed the relationships between the Emotional Problems Scale, two circumplex measures of personality, personality disorder assessments and risk assessments in 212 offenders with intellectual disability. Previous studies had established the reliability and validity of these measures with the client group. Strong relationships emerged between externalizing emotional problems and dominant and hostile personality dimensions with weaker but significant relationships between internalizing problems and submissive and hostile dimensions. Externalizing problems were strongly associated with risk for violence, while internalizing problems had a weaker but significant relationship with some historical and clinical risk scales. Dominant personality dimensions were associated with narcissistic personality disorder and nurturant personality dimensions negatively associated with anti-social personality disorder. It would seem that there are orderly, significant relationships among measures of personality, personality disorders, emotional problems and risk. We discuss the implications of emotional assessment for the evaluation of risk and prediction of treatment progress.

Psychological dimensions of antisocial personality disorder as predictors of psychotherapy noncompletion among sexual offenders

The goal of this study was to examine whether psychological dimensions of antisocial personality disorder (ASPD), as conceptualized by Kernberg (1992), could predict psychotherapy noncompletion (PNC) among 50 men found guilty of sexual abuse of children. All participants began a 65-week, court-mandated course of cognitive-behavioral psychotherapy, which 20 (40%) of them did not complete. Pretherapy personality was assessed with the Structured Clinical Interview for DSM Axis II Disorders (First, Spitzer, Gibbon, Williams, & Benjamin, 1997), the Personality Organization Diagnostic Form (Diguer, Normandin, & Hébert, 2001), and Blatt and colleagues' (Blatt, Bers, & Schaffer, 1993; Blatt, Chevron, Quinlan, Schaffer, & Wein, 1988) scales of mental representations, as well as the State-Trait Anger Expression Inventory (Spielberger, 1988). A discriminant function analysis, which explained 46% of the total variance, showed that descriptive (antisocial and narcissistic personality disorders), psychological (primitive defense mechanisms, identity diffusion and self-representations), and demographic (work status and income) variables predicted PNC. The classification analysis correctly classified 78% of the participants. These findings support the hypothesis that psychological dimensions of ASPD help explain PNC among sexual offenders. The authors discuss the theoretical and clinical implications of these results.
