Combined dialectical behavior therapy and fluoxetine in the treatment of borderline personality disorder.

BACKGROUND: This study examines the therapeutic effect of fluoxetine, a selective serotonin reuptake inhibitor, added to dialectical behavior therapy (DBT), an empirically supported psychosocial therapy, for the treatment of borderline personality disorder. METHOD: This is a 12-week, randomized, double-blind, placebo-controlled study of patients with borderline personality disorder (identified using the Structured Clinical Interview for DSM-IV Axis II Disorders). All subjects received individual and group DBT. Of the 20 subjects that completed treatment, 9 were randomly assigned to receive up to 40 mg/day of fluoxetine and 11 were randomly assigned to the placebo condition. Subjects were evaluated at baseline and at week 10 or 11 on self-report measures of depression, anxiety, anger expression, dissociation, and global functioning. The study was conducted between January 1998 and February 2000. RESULTS: Time-by-group interaction effects revealed no significant group differences in scores from pre-treatment to posttreatment on any measure. However, within the DBT/placebo group, there were significant pretreatment/posttreatment differences in the direction of improvement on all measures. No significant pre-treatment/posttreatment differences were found within the DBT/fluoxetine condition. CONCLUSION: The data suggest that adding fluoxetine to an efficacious psychosocial treatment does not provide any additional benefits. Further studies with larger sample sizes are warranted.

Major depressive disorder and borderline personality disorder revisited: longitudinal interactions.

BACKGROUND: This report investigates the longitudinal association of changes in major depressive disorder (MDD) and borderline personality disorder. METHOD: A DSM-IV-diagnosed sample of 161 patients with borderline personality disorder who have been followed with repeated measures at 6, 12, 24, and 36 months are investigated to see whether those with co-occurring MDD differ at baseline and in their course. Proportional hazard regression and cross-lagged panel analyses are used to demonstrate whether changes in the course of either disorder have predictable effects on the course of the other. RESULTS: The rate of remissions of borderline personality disorder was not affected by whether patients had co-occurring MDD. The rate of MDD remissions was significantly reduced by co-occurring borderline personality disorder. Both regression analyses and panel analyses indicated that improvements in borderline personality disorder were often followed by improvements in MDD but that improvements in MDD were not followed by improvements in borderline personality disorder. Five of the 9 borderline criteria, including those that most relate to affects, were particularly apt to remit prior to MDD remissions. CONCLUSIONS: When borderline personality disorder and MDD co-occur, they can sometimes have independent courses, but more often improvements in MDD are predicted by prior improvements in borderline personality disorder. Clinicians should not ignore borderline personality disorder in hopes that treatment of MDD will be followed by improvement of borderline personality disorder.

The natural course of bulimia nervosa and eating disorder not otherwise specified is not influenced by personality disorders.

OBJECTIVE: To examine prospectively the natural course of bulimia nervosa (BN) and eating disorder not otherwise specified (EDNOS) and to test the effects of personality disorder (PD) comorbidity on the outcomes. METHOD: Ninety-two female patients with current BN (N=23) or EDNOS (N=69) were evaluated at baseline enrollment in the Collaborative Longitudinal Personality Disorders Study (CLPS). Eating disorders (EDs) were assessed with the Structured Clinical Interview for DSM-IV Axis I Disorders. Personality disorders (PDs) were assessed with the Diagnostic Interview for DSM-IV PD (DIPD-IV). The course of BN and EDNOS was assessed with the Longitudinal Interval Follow-up Evaluation and the course of PDs was evaluated with the Follow-Along version of the DIPD-IV at 6, 12, and 24 months. RESULTS: Probability of remission at 24 months was 40% for BN and 59% for EDNOS. To test the effects of PD comorbidity on course, ED patients were divided into groups with no, one, and two or more PDs. Cox proportional regression analyses revealed that BN had a longer time to remission than EDNOS (p<.05). The number of PDs was not a significant predictor of time to remission, nor was the presence of Axis I psychiatric comorbidity or Global Assessment of Functioning scores. Analyses using proportional hazards regression with time-varying covariates revealed that PD instability was unrelated to changes in ED. CONCLUSIONS: BN has a worse 24-month course (longer time to remission) than EDNOS. The natural course of BN and EDNOS is not influenced significantly by the presence, severity, or time-varying changes of co-occurring PDs, co-occurring Axis I disorders, or by global functioning.

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.

Childhood antecedents of avoidant personality disorder: a retrospective study.

OBJECTIVE: To explore potential risk factors and early manifestations of avoidant personality disorder (AVPD) by examining retrospective reports of social functioning and adverse childhood experiences. METHOD: Early social functioning and pathological childhood experiences were assessed using the Childhood Experiences Questionnaire-Revised. The responses of 146 adults diagnosed with primary AVPD were compared with a group of 371 patients with other personality disorders as a primary diagnosis and a group of 83 patients with current major depression disorder and no personality disorders, using chi2 analyses. Diagnoses were based on semistructured interviews by trained reliable clinicians. RESULTS: Adults with AVPD reported poorer child and adolescent athletic performance, less involvement in hobbies during adolescence, and less adolescent popularity than the depressed comparison group and the other personality disorder group. Reported rates of physical and emotional abuse were higher than the depressed group, but this result was influenced by comorbid diagnoses. CONCLUSIONS: These results suggest that early manifestations of AVPD are present in childhood but that various forms of abuse are not specific to the disorder.

Clinical features and impairment in women with Borderline Personality Disorder (BPD) with Posttraumatic Stress Disorder (PTSD), BPD without PTSD, and other personality disorders with PTSD.

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 II disorders and compared on selected clinical variables. The additional diagnosis of PTSD in borderline women did not significantly increase the degree of borderline pathology and psychiatric morbidity but did significantly increase general dysfunction and the occurrence of hospitalization. The additional diagnosis of BPD in women with PTSD significantly increased the features of suicide proneness and impulsiveness. Both groups of women with PTSD reported significantly more types of childhood traumas relative to borderline women without PTSD. Consistent with other research, the findings suggest that PTSD does not appear to alter the central features of BPD. The clinical implications of our findings are considered.

Stability as a distinction between Axis I and Axis II disorders.

Temporal stability has served as a conceptual basis for the distinction between the clinical syndromes of Axis I disorders and the Axis II personality disorders, the latter being viewed as lifelong enduring patterns. However, comparisons of the stability of Axis I and II disorders have been limited. The present review examines findings from three naturalistic longitudinal studies that utilize similar methodology: the Collaborative Longitudinal Personality Disorders Study (CLPS; Gunderson et al., 2000), the Collaborative Depression Study (CDS; Katz & Klerman, 1979), and the Harvard/Brown Anxiety Research Program (HARP; Keller et al., 1994). Using a definition of remission/recovery as having no or minimal symptoms for 8 consecutive weeks, the courses of personality, depressive, and anxiety disorders were compared. Though remission/recovery rate at the 2-year follow-up was highest for mood disorders, the probability of recurrence was also particularly high. Personality disorders, with remission rates higher than the anxiety disorders, appear to be less stable than conceptualized. The anxiety disorders had remarkably low recovery rates even beyond 5 years of prospective follow-up. Factors that may explain these findings, as well as implications for future conceptualization of DSM, are discussed.

Plausibility and possible determinants of sudden "remissions" in borderline patients.

THIS STUDY documents dramatic improvements in patients with borderline personality disorder (BPD) and explores their possible determinants. From a sample of the 160 carefully diagnosed borderline patients on whom prospective follow-along data was collected, a subsample of 18 was identified whose DSM-IV criteria count fell to two or fewer during the course of the first 6 months of the study and retained that improvement for the next 6 months. Follow-along data including month-by-month ratings of BPD criteria; week-by-week ratings of Axis I disorders, medication changes, and life events were then used to establish concensus ratings on four hypothesized causes: Axis I remissions, situational change, misdiagnosis, and treatment effects. Follow-up data collected at 2 years was examined to see whether the improvements persisted. The results were that 18 BPD patients underwent dramatic improvements in the first 6 months. Only one had relapsed by 2 years. Though one was judged to have been misdiagnosed at baseline, the most important determinants were judged to be situational changes (n = 10) and remissions of co-occurring Axis I disorders (n = 7). In 10 patients treatment appeared to have facilitated these situational or Axis I resolutions. In conclusion, patients with BPD can make significant improvements that are rapid and of sufficient duration to be considered remissions. Determinants were identified that warrant further prospective evaluation.

Traumatic exposure and posttraumatic stress disorder in borderline, schizotypal, avoidant, and obsessive-compulsive personality disorders: findings from the collaborative longitudinal personality disorders study.

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 compared. Results indicate that BPD participants reported the highest rate of traumatic exposure (particularly to sexual traumas, including childhood sexual abuse), the highest rate of posttraumatic stress disorder, and youngest age of first traumatic event. Those with the more severe PDs (schizotypal, BPD) reported more types of traumatic exposure and higher rates of being physically attacked (childhood and adult) when compared to other groups. These results suggest a specific relationship between BPD and sexual trauma (childhood and adult) that does not exist among other PDs. In addition, they support an association between severity of PD and severity of traumatic exposure, as indicated by earlier trauma onset, trauma of an assaultive and personal nature, and more types of traumatic events.

Affect regulation in women with borderline personality disorder traits.

Affect dysregulation is considered a defining feature of borderline personality disorder (BPD). In spite of this, there is a dearth of empirical research that examines affect regulation among persons with BPD. The present study examined the relationship between specific dimensions of affect regulation and borderline traits in a sample of 39 patients. Participants were administered the Personality Diagnostic Questionnaire-Revised to assess the degree of borderline traits and the Affect Intensity Measure and Affect Control Scale to assess dimensions of affect regulation, selected based on the biosocial theory of BPD. Results from hierarchical regression analyses indicated that level of affect intensity and affect control were significantly associated with number of BPD traits, even after controlling for level of depression. Findings for affect control remained significant even after controlling for affect intensity. These results, consistent with biosocial theory of BPD, suggest that persons with BPD experience emotions more intensely and have greater difficulty in controlling their affective responses.

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.

Ethnicity and four personality disorders.

The current study examined the relationship between ethnicity and DSM-IV personality disorders. The distribution of four personality disorders--borderline (BPD), schizotypal (STPD), avoidant (AVPD), and obsessive-compulsive (OCPD)--along with their criteria sets, were compared across three ethnic groups (Caucasians, African Americans, and Hispanics) using both a clinician-administered diagnostic interview and a self-report instrument. Participants were 554 patients drawn from the Collaborative Longitudinal Personality Disorders Study (CLPS) who comprised these three ethnic groups and met personality disorder criteria based on reliably administered semistructured interviews. Chi-square analyses revealed disproportionately higher rates of BPD in Hispanic than in Caucasian and African American participants and higher rates of STPD among African Americans when compared to Caucasians. Self-report data reflected similar patterns. The findings suggest that in treatment-seeking samples, Caucasians, Hispanics, and African Americans may present with different patterns of personality pathology. The factors contributing to these differences warrant further investigation.
