Co-Occurring Substance Use and Personality Disorders: Current Thinking on Etiology,Diagnosis, and Treatment

ABSTRACT

Despite the high prevalence of personality disorders among substance abusing individuals, the literature on these co-occurring disorders is limited. This paper reviews the literature and provides the most current data on the demographics, the criteria for diagnosing both personality disorders and substance use disorders, and the effects of substance abuse and co-occurring personality disorders, particularly antisocial and borderline, on prognoses and treatment approaches. Recommendations for further research on these co-occurring disorders are provided.
