The comorbidity of alcoholism and personality disorders in a clinical population: prevalence rates and relation to alcohol typology variables.
This study assessed prevalence rates and overlap among Diagnostic and Statistical Manual of Mental Disorders (3rd ed., revised; DSM-III-R; American Psychiatric Association, 1987) personality disorders in a multisite sample of 366 substance abusers in treatment. In addition, the relation of antisocial personality disorder (APD), borderline personality disorder (BPD), and paranoid personality disorder (PPD) to alcohol typology variables was examined. Structured diagnostic interviews and other measures were administered to participants at least 14 days after entry into treatment. Results indicated high prevalence rates for APD and non-APD disorders. There was extensive overlap between Axis I disorders and personality disorders, and among personality disorders themselves. APD, BPD, and PPD were linked to more severe symptomatology of alcoholism and other clinical problems. However, only APD and BPD satisfied subtyping criteria, after controlling for other comorbidity. Implications for classifying alcoholics by comorbid disorders are discussed.
