Cognitive behavior therapy has been shown to be effective in the treatment of generalized anxiety disorder (GAD) and social phobia. However, little is known regarding best treatment practices when these disorders co-occur. The following is an illustration of a successful implementation of an empirically supported treatment for GAD with a gay Caucasian client with co-occurring social phobia and GAD in addition to concurrent depressive symptomatology. Particular emphasis was placed on the use of a functional assessment in case conceptualization and in treatment planning, which suggested that the client's socially anxious and depressive symptomatology were related to his chronic worry. At termination, criteria for GAD and social phobia were no longer met, and depressive symptomatology was reduced to minimal levels. Ongoing assessment demonstrated clinically significant treatment gains. Additionally, the importance of homework completion is demonstrated and discussed.
