Stability of functional impairment in patients with schizotypal, borderline, avoidant, or obsessive–compulsive personality disorder over two years

BACKGROUND A defining feature of personality disorder (PD) is an enduring pattern of inner experience and behavior that is stable over time. Follow-up and follow-along studies have shown considerable diagnostic instability of PDs, however, even over short intervals. What, then, about personality disorder is stable? The purpose of this study was to determine the stability of impairment in psychosocial functioning in patients with four different PDs, in contrast to patients with major depressive disorder (MDD) and no PD, prospectively over a 2-year period. METHOD Six hundred treatment-seeking or treated patients were recruited primarily from clinical services in four metropolitan areas of the Northeastern USA. Patients were assigned to one of five diagnostic groups: schizotypal (STPD) (n=81), borderline (BPD) (n=155), avoidant (AVPD) (n=137), or obsessive-compulsive (OCPD) (n=142) personality disorders or MDD and no PD (n=85), based on the results of semi-structured interview assessments and self-report measures. Impairment in psychosocial functioning was measured using the Longitudinal Interval Follow-up Evaluation (LIFE) at baseline and at three follow-up assessments. RESULTS Significant improvement in psychosocial functioning occurred in only three of seven domains of functioning and was largely the result of improvements in the MDD and no PD group. Patients with BPD or OCPD showed no improvement in functioning overall, but patients with BPD who experienced change in personality psychopathology showed some improvement in functioning. Impairment in social relationships appeared most stable in patients with PDs. CONCLUSION Impairment in functioning, especially social functioning, may be an enduring component of personality disorder.

Toward a Model for Assessing Level of Personality Functioning in DSM–5, Part I: A Review of Theory and Methods

Personality disorders are associated with fundamental disturbances of self and interpersonal relations, problems that vary in severity within and across disorders. This review surveyed clinician-rated measures of personality psychopathology that focus on self–other dimensions to explore the feasibility and utility of constructing a scale of severity of impairment in personality functioning for DSM–5. Robust elements of the instruments were considered in creating a continuum of personality functioning based on aspects of identity, self-direction, empathy, and intimacy. Building on preliminary findings (Morey et al., 2011/this issue), the proposed Levels of Personality Functioning will be subjected to extensive empirical testing in the DSM–5 field trials and elsewhere. The resulting version of this severity measure is expected to have clinical utility in identifying personality psychopathology, planning treatment, building the therapeutic alliance, and studying treatment course and outcome.

Gender differences in borderline personality disorder: findings from the collaborative longitudinal personality disorders study

A majority of the literature on borderline personality disorder (BPD) focuses on its occurrence in women or does not specifically assess for gender differences in clinical presentations. Some studies report that men with BPD may be more likely to be diagnosed with substance use disorders, as well as paranoid, passive-aggressive, narcissistic, sadistic, and antisocial personality disorders (PDs). Additionally, women with BPD appear to be more likely to report histories of adult physical and sexual abuse and to meet diagnostic criteria for post-traumatic stress disorder (PTSD) and eating disorders. The purpose of the present study was to further examine gender differences in BPD. Using baseline data from the Collaborative Longitudinal Personality Disorders Study (CLPS), men and women who met criteria for BPD were compared on current axis I and II disorders, BPD diagnostic criteria, childhood trauma histories, psychosocial functioning, temperament, and personality traits. Men with BPD were more likely to present with substance use disorders, and with schizotypal, narcissistic, and antisocial PDs, while women with BPD were more likely to present with PTSD, eating disorders, and the BPD criterion of identity disturbance. Generally speaking, women and men with BPD displayed more similarities than differences in clinical presentations. The differences that did emerge are consistent with those found in epidemiological studies of psychopathology and therefore do not appear unique to BPD. Additionally, many gender differences traditionally found in epidemiological samples did not emerge in BPD subjects. For example, no difference was found in rates of major depressive disorder, a condition that is more prevalent in females. Thus, BPD pathology may be a prevailing characterization that can attenuate usual gender-based distinctions.

Proposed changes in personality and personality disorder assessment and diagnosis for DSM-5 part I: description and rationale

A major reconceptualization of personality psychopathology has been proposed for DSM-5 that identifies core impairments in personality functioning, pathological personality traits, and prominent pathological personality types. A comprehensive personality assessment consists of four components: levels of personality functioning, personality disorder types, pathological personality trait domains and facets, and general criteria for personality disorder. This four-part assessment focuses attention on identifying personality psychopathology with increasing degrees of specificity, based on a clinicians available time, information, and expertise. In Part I of this two-part article, we describe the components of the new model and present brief theoretical and empirical rationales for each. In Part II, we will illustrate the clinical application of the model with vignettes of patients with varying degrees of personality psychopathology, to show how assessments might be conducted and diagnoses reached.

Axis I and Axis II Disorders as Predictors of Prospective Suicide Attempts: Findings From the Collaborative Longitudinal Personality Disorders Study

This study examined diagnostic predictors of prospectively observed suicide attempts in a personality disorder (PD) sample. During 2 years of follow-up, 58 participants (9%) reported at least 1 definitive suicide attempt. Predictors that were examined include 4 PD diagnoses and selected Axis I diagnoses (baseline and course). Multivariate logistic regression analyses indicated that baseline borderline personality disorder (BPD) and drug use disorders significantly predicted prospective suicide attempts. Controlling for baseline BPD diagnosis, proportional hazards analyses showed that worsening in the course of major depressive disorder (MDD) and of substance use disorders in the month preceding the attempt were also significant predictors. Therefore, among individuals diagnosed with PDs, exacerbation of Axis I conditions, particularly MDD and substance use, heightens risk for a suicide attempt.

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.

Toward a model for assessing level of personality functioning in DSM-5, part II: Empirical articulation of a core dimension of personality pathology

The extensive comorbidity among Diagnostic and Statistical Manual of Mental Disorders (4th ed. [DSM–IV]; American Psychiatric Association, 1994) personality disorders might be compelling evidence of essential commonalities among these disorders reflective of a general level of personality functioning that in itself is highly relevant to clinical decision making. This study sought to identify key markers of such a level, thought to reflect a core dimension of personality pathology involving impairments in the capacities of self and interpersonal functioning, and to empirically articulate a continuum of severity of these problems for DSM–5. Using measures of hypothesized core dimensions of personality pathology, a description of a continuum of severity of personality pathology was developed. Potential markers at various levels of severity of personality pathology were identified using item response theory (IRT) in 2 samples of psychiatric patients. IRT-based estimates of participants’ standings on a latent dimension of personality pathology were significantly related to the diagnosis of DSM–IV personality disorder, as well as to personality disorder comorbidity. Further analyses indicated that this continuum could be used to capture the distribution of pathology severity across the range of DSM–IV personality disorders. The identification of a continuum of personality pathology consisting of impairments in self and interpersonal functioning provides an empirical foundation for a “levels of personality functioning” rating proposed as part of a DSM–5 personality disorder diagnostic formulation.

WHY ARE WOMEN DIAGNOSED BORDERLINE MORE THAN MEN

DSM-IV-TR states that borderline personality disorder (BPD) is “diagnosed predominantly (about 75%) in females.” A 3:1 female to male gender ratio is quite pronounced for a mental disorder and, consequently, has led to speculation about its cause and to some empirical research. The essential question is whether the higher rate of BPD observed in women is a result of a sampling or diagnostic bias, or is it a reflection of biological or sociocultural differences between women and men? Data to address these issues are reviewed. The differential gender prevalence of BPD in clinical settings appears to be largely a function of sampling bias. True prevalence by gender is unknown. The modest empirical support for diagnostic biases of various kinds would not account for a wide difference in prevalence between the genders. Biological and sociocultural factors provide potentially illuminating hypotheses, should the true prevalence of BPD differ by gender.

Recent life events preceding suicide attempts in a personality disorder sample : Findings from the collaborative longitudinal personality disorders study

Few studies have examined the relationship between life events, suicide attempts, and personality disorders (PDs), in spite of the strong associations between PDs and suicidal behavior, and the poor coping strategies often exhibited by these individuals. The authors examined whether participants with PDs who attempted suicide during the first 3 years of a prospective, longitudinal study were more likely to experience specific life events in the month during and preceding the suicide attempt. Of 489 participants with PDs, 61 attempted suicide during the 3-year, follow-up interval. Results indicated that negative life events, particularly those pertaining to love-marriage or crime-legal matters, were significant predictors of suicide attempts, even after controlling for baseline diagnoses of borderline PD, major depressive disorders, substance use disorders, and a history of childhood sexual abuse. Therefore, certain types of negative life events are unique risk factors for imminent suicide attempts among individuals with PDs.

Stressful life events as predictors of functioning: findings from the Collaborative Longitudinal Personality Disorders Study

Objective:  Although much attention has been given to the effects of adverse childhood experiences on the development of personality disorders (PDs), we know far less about how recent life events influence the ongoing course of functioning. We examined the extent to which PD subjects differ in rates of life events and the extent to which life events impact psychosocial functioning.
