The aims of this study were to examine differences in clinical features, impairment, and types of childhood traumas among women with borderline personality disorder (BPD), women with BPD and posttraumatic stress disorder (PTSD), and those with other personality disorders and PTSD. Using baseline data from the Collaborative Longitudinal Study of Personality Disorders, 186 women were divided into 3 groups (BPD+PTSD, BPD, PTSD), based on structured diagnostic interviews for Axis I and Axis ...

OBJECTIVE: To examine prospectively the natural course of bulimia nervosa and eating disorder not otherwise specified (EDNOS) and to test for the effects of personality disorder psychopathology on remission and relapse.

METHOD: Subjects were 92 female patients with current bulimia nervosa (N = 23) or EDNOS (N = 69) at baseline enrollment in the Collaborative Longitudinal Personality Disorders Study. Axis I psychiatric disorders (including eating disorders) were assessed with the ...

CONTEXT: Borderline personality disorder (BPD) is traditionally considered chronic and intractable.

OBJECTIVE: To compare the course of BPD's psychopathology and social function with that of other personality disorders and with major depressive disorder (MDD) over 10 years.

DESIGN: A collaborative study of treatment-seeking, 18- to 45-year-old patients followed up with standardized, reliable, and repeated measures of diagnostic remission and relapse and of both global social functioning ...

OBJECTIVE: To examine prospectively the course of major depressive disorder (MDD) and to test for the moderating effects of personality disorder (PD) comorbidity on relapse after remission from an episode of MDD.

METHOD: Participants were 303 patients (196 women and 107 men) with current DSM-IV-diagnosed MDD at baseline enrollment in the Collaborative Longitudinal Personality Disorders Study. Major depressive disorder and Axis I psychiatric disorders were assessed with the Structured ...

The association between trauma and personality disorders (PDs), while receiving much attention and debate, has not been comprehensively examined for multiple types of trauma and PDs. The authors examined data from a multisite study of four PD groups: schizotypal, borderline (BPD), avoidant, and obsessive-compulsive, and a major depression comparison group. Rates of traumatic exposure to specific types of trauma, age of first trauma onset, and rates of posttraumatic stress disorder are ...

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 ...

OBJECTIVE: Utilization of mental health treatment was compared in patients with personality disorders and patients with major depressive disorder without personality disorder.

METHOD: Semistructured interviews were used to assess diagnosis and treatment history of 664 patients in four representative personality disorder groups-schizotypal, borderline, avoidant, and obsessive-compulsive-and in a comparison group of patients with major depressive disorder.

RESULTS: Patients with ...

BACKGROUND: In the context of much literature and conjecture about the relationship of personality disorders (PD) and major depressive disorder (MDD), this paper uses longitudinal data to assess the frequency with which PD patients, and especially those with borderline personality disorder (BPD), have recurrences (for patients with lifetime histories), or new onsets (for patients without lifetime histories) of MDD.

METHODS: A sample of 478 PD patients received reliable repeated follow-up ...

OBJECTIVE: Personality disorders are defined as enduring patterns of maladaptive behaviors and traits that are stable over time. This study prospectively examined the stability of four personality disorders (schizotypal, borderline, avoidant, and obsessive-compulsive) over a 1-year follow-up period.

METHOD: Subjects (N=668) were recruited from multiple clinical settings at four collaborating institutions. Subjects met criteria for one or more of the four personality disorders or were ...

OBJECTIVE: Depressive personality disorder was introduced into DSM-IV's appendix amid controversy. While that disorder appears to be a reliable and valid one, the authors offer new data about its relationship to major depression, dysthymic disorder, and other personality disorders.

METHOD: The authors assessed 54 subjects with early-onset, long-standing mild depressive features for depressive personality disorder, axis I and axis II disorders, family history, and treatment history; they ...

OBJECTIVE: This study tracked the individual criteria of four DSM-IV personality disorders-borderline, schizotypal, avoidant, and obsessive-compulsive personality disorders-and how they change over 2 years.

METHOD: This clinical sample of patients with personality disorders was derived from the Collaborative Longitudinal Personality Disorders Study and included all participants with borderline, schizotypal, avoidant, or obsessive-compulsive personality disorder for whom complete 24-month ...

BACKGROUND: This study prospectively examined the natural clinical course of six anxiety disorders over 7 years of follow-up in individuals with personality disorders (PDs) and/or major depressive disorder. Rates of remission, relapse, new episode onset and chronicity of anxiety disorders were examined for specific associations with PDs.

METHOD: Participants were 499 patients with anxiety disorders in the Collaborative Longitudinal Personality Disorders Study, who were assessed with ...

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 ...

OBJECTIVE: The purpose of this study was to compare psychosocial functioning in patients with schizotypal, borderline, avoidant, or obsessive-compulsive personality disorder and patients with major depressive disorder and no personality disorder.

METHOD: Patients (N=668) were recruited by the four clinical sites of the Collaborative Longitudinal Personality Disorders Study. The carefully diagnosed study groups were compared on an array of domains of psychosocial functioning, as measured ...
