Cognitive-behavioral therapy for obsessive-compulsive disorder: A review of the treatment literature

Once considered a rare and largely untreatable condition, obsessive-compulsive disorder (OCD) is now known lobe the fourth most common psychiatric disorder Obsessive thoughts are intrusive, repugnant, and distress and anxiety provoking, whereas compulsive rituals often lead to significant impairment in many areas of life. In this article, the authors present an empirically based review of the treatment outcome literature on cognitive-behavioral therapy for OCD. Specifically, treatment by exposure with response prevention (EX/RP) has been demonstrated to be effective in reducing OCD symptoms. The effectiveness of different variations of EX/RP and comparisons between this and other psychosocial therapies (e.g., cognitive therapy) are also discussed. Finally, the authors consider studies that have examined variables thought to influence the effectiveness of treatment.
