Researchers from Curtin University of Technology in Perth, Western Australia, compared the effectiveness of group vs. individual Cognitive Behavioral Therapy for obsessive-compulsive disorder (OCD) and found both programs highly effective by the time of follow-up.

Researchers from the School of Psychology at Curtin University of Technology in Perth, Western Australia, compared the effectiveness of group vs. individual Cognitive Behavioral Therapy for obsessive-compulsive disorder (OCD).

Subjects were randomly assigned to either a 10-week individual CBT program, an identical, 10-week group CBT program or a wait-list condition. Large effect sizes were found for both treatment conditions. Analysis of clinically significant change showed that, although the individual treatment program was associated with a more rapid response, both treatments had equivalent rates of recovered participants by the time of follow-up.
