Treatment utilization by patients with personality disorders.

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 personality disorders had more extensive histories of psychiatric outpatient, inpatient, and psychopharmacologic treatment than patients with major depressive disorder. Compared to the depression group, patients with borderline personality disorder were significantly more likely to have received every type of psychosocial treatment except self-help groups, and patients with obsessive-compulsive personality disorder reported greater utilization of individual psychotherapy. Patients with borderline personality disorder were also more likely to have used antianxiety, antidepressant, and mood stabilizer medications, and those with borderline or schizotypal personality disorder had a greater likelihood of having received antipsychotic medications. Patients with borderline personality disorder had received greater amounts of treatment, except for family/couples therapy and self-help, than the depressed patients and patients with other personality disorders. CONCLUSIONS: These results underscore the importance of considering personality disorders in diagnosis and treatment of psychiatric patients. Borderline and schizotypal personality disorder are associated with extensive use of mental health resources, and other, less severe personality disorders may not be addressed sufficiently in treatment planning. More work is needed to determine whether patients with personality disorders are receiving adequate and appropriate mental health treatments.

Patterns of personality pathology in patients with generalized anxiety disorder, panic disorder with and without agoraphobia, and social phobia.

The relationship between co-occurring personality disorders and anxiety disorders (panic disorder with or without agoraphobia, social phobia, and generalized anxiety disorder) was examined, taking into account the effect of major depression. This article describes findings for 622 participants in the Harvard/Brown Anxiety Research Project, a longitudinal follow-up study of DSM-III-R-defined anxiety disorders. A total of 24% of participants had at least one personality disorder, with avoidant, obsessive compulsive, dependent, and borderline most common. Generalized anxiety disorder, social phobia, and major depression were positively associated with the occurrence of one or more personality disorders, whereas panic disorder with agoraphobia was not associated. Major depression was associated in particular with dependent, borderline, histrionic, and obsessive compulsive personality disorders and social phobia was associated with avoidant personality disorder. Whereas some of our findings confirm results from earlier studies, others are somewhat inconsistent with previous results and indicate the need for further investigation.

An eight-year longitudinal comparison of clinical course and characteristics of social phobia among men and women.

OBJECTIVE: Social phobia is a chronic disorder with a higher prevalence among women than men. Data from an eight-year longitudinal study were analyzed to investigate the course of social phobia and to explore potential sex differences in the course and characteristics of the illness. METHODS: Data were analyzed from the Harvard/Brown Anxiety Research Program, a naturalistic, observational study begun in 1989 in which patients with social phobia are assessed every six to 12 months. Treatment was observed but not prescribed by the program personnel. Data on comorbidity, remission, and health-related quality of life were collected for 176 patients with social phobia. RESULTS: Only 38 percent of women and 32 percent of men experienced a complete remission during the eight-year study period, a difference that was not significant. A larger proportion of women than men had the generalized form of social phobia, although the difference was not significant. Women were more likely to have concurrent agoraphobia, and men had a higher rate of comorbid substance use disorders. Social phobia had a more chronic course among women who had low Global Assessment of Functioning scores and a history of suicide attempts at baseline than among men who had these characteristics. Health-related quality of life was similar for both men and women, except that women were slightly but significantly more impaired in household functioning. CONCLUSIONS: The chronicity of social phobia was striking for both men and women. Although remission rates did not differ significantly between men and women, clinicians should be alert to the fact that women with poor baseline functioning and a history of suicide attempts have the greatest chronicity of illness.

Factors predicting the clinical course of generalised anxiety disorder.

BACKGROUND: Cross-sectional data show that generalised anxiety disorder (GAD) is a chronic condition with episodes lasting much longer than the six-month minimum required by DSM-III-R and DSM-IV. Although GAD is chronic, little is known about factors influencing illness duration. AIMS: To investigate variables that influence the clinical course of GAD. METHOD: A total of 167 patients with GAD participated in the Harvard-Brown Anxiety Research Program. Patients were assessed at intake and re-examined at six- to twelve-month intervals for five years. Kaplan-Meier curves were constructed to assess the likelihood of remission. Regression analysis was used to investigate factors predicting full or partial remission. RESULTS: The rate of remission was 0.38 after five years. Diminished likelihood of remission was associated with low overall life satisfaction, poor spousal or family relationships, a concurrent cluster B or C personality disorder and a low global assessment score. CONCLUSIONS: Full or partial remissions were less likely to occur in patients with poor relationships and personality disorders. These patients should be given more intensive and possibly multi-modal therapy.

Co-occurrence of mood and personality disorders: a report from the Collaborative Longitudinal Personality Disorders Study (CLPS).

The purpose of this study was to examine the relationship of subtypes and particular clinical features of mood disorders to co-occurrence with specific personality disorders. Five hundred and seventy-one subjects recruited for the Collaborative Longitudinal Personality Disorders Study (CLPS) were assessed with the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) and the Diagnostic Interview for DSM-IV Personality Disorders (DIPD-IV). Percent co-occurrence rates for current and lifetime mood disorders with personality disorders were calculated. Logistic regression analyses examined the effects of clinical characteristics of depressive disorders (e.g., age at onset, recurrence, symptom severity, double depression, and atypical features) on personality disorder co-occurrence. In comparison with other DSM-IV personality disorders, avoidant, borderline, and dependent personality disorders (PDs) were most specifically associated with mood disorders, particularly depressive disorders. Severity and recurrence of major depressive disorder and comorbid dysthymic disorder predicted co-occurrence with borderline and to a lesser extent research criteria depressive personality disorders. The results are consistent with the view that a mood disorder with an insidious onset and recurrence, chronicity, and progression in severity leads to a personality disorder diagnosis in young adults.
