Dual diagnosis: Clinical issues in substance abuse treatment

Dual diagnosis within the context of alcohol and substance abuse has become the focus of considerable interest, particularly when related to anxiety and depression. Depressive symptomatology is frequently associated with substance abuse and chemical dependency and numerous studies report a high concordance with these diagnostic entities and major affective disorder (Galanter,Casteneda, & Ferman, 1988). Depressive symptoms are also related to post treatment of alcohol and substance abuse with reported occurrences of 75 percent occurring with patients who have experienced relapse (Biedermann, Newcome, & Sprich, 1991).
