The purpose of this case study was to assess the treatment effectiveness of Cognitive Behavioral Therapy (CBT) on a client with a dual diagnosis of major depressive disorder and opioid dependence. The client exhibited severe depressive symptoms along with symptoms of opioid dependence. The client's depressive disorder was the primary diagnosis on Axis I due to onset of symptoms beginning before substance use began. A review of major studies evaluating Cognitive Behavioral Therapy with depressive disorders and substance dependence was conducted. Studies which evaluated the use of Cognitive Behavioral Therapy as a treatment modality alone and coupled with psychotropic medications were reviewed along with studies comparing CBT with and without medications against other types of treatment modalities. The client received treatment at a community based program using CBT techniques. The Beck's Depression Inventory (BDI) was administered before and after treatment. Results indicated that CBT was effective treatment for the client in the study with a diagnosis of depression and opioid dependence. Self report and follow-up contacts at three weeks, eight weeks and 14 weeks after discharge also supported the conclusion that the treatment was effective. The need for more research in the area of dual diagnosed individuals and CBT is discussed.
