%0 Journal Article %T The Relationship between Concurrent Substance Use Disorders and Eating Disorders with Personality Disorders %A Christine Courbasson %A Jacqueline M. Brunshaw %J International Journal of Environmental Research and Public Health %D 2009 %I MDPI AG %R 10.3390/ijerph6072076 %X Objective: The current pilot study investigated whether patients with concurrent substance use disorders and eating disorders (SUD and ED) who experienced a reduction in SUD and ED symptoms following treatment for SUD and ED also experienced a reduction in personality disorder (PD) symptoms. Method: Twenty patients with SUD and ED and PD were assessed pre and post treatment using clinical interviews, self-report questionnaires, and a therapist questionnaire on DSM-IV-TR symptoms for PD. Results: Symptoms for the personality disorders were reduced following treatment. This reduction was correlated with a decrease in the number of symptoms of ED at post treatment. Discussion: Chronic concurrent SUD and ED may make it difficult to separate PD symptoms from co-occurring disorders. Many features attributed to PDs may be reduced when problematic substance use and disordered eating are addressed, a fact that may increase clinician and patients¡¯optimism about therapeutic change. %K substance use disorders %K eating disorders %K personality disorders %K avoidant personality disorder %K borderline personality disorder %K obsessive compulsive personality disorder %U http://www.mdpi.com/1660-4601/6/7/2076
