Group behavioral therapy for adolescents with tic-related and non-tic-related obsessive-compulsive disorder.

Prior research supports the distinction between tic-related and non-tic-related obsessive-compulsive disorder (OCD) based on phenomenologic, etiologic, and neurobehavioral data. The present study examines whether response to psychosocial treatment differs in adolescents, depending on the presence of comorbid tics. Nineteen adolescents, 12-17 years of age, participated in 7-week, uncontrolled trial of group cognitive-behavioral treatment (CBT) for OCD. Eight of the patients had tic-related and eleven had non-tic-related OCD. The group CBT program included psycho-education, exposure and response prevention, cognitive strategies, and family involvement. Significant improvement was observed for all subjects on the Yale-Brown Obsessive Compulsive Scale ratings of obsessions, compulsions, and total OCD symptoms. Outcomes were similar for subjects with tic-related and non-tic-related OCD. These preliminary results suggest that the presence of comorbid tic disorders may not attenuate response to behavioral group treatment among adolescents. Copyright 2003 Wiley-Liss, Inc.
