Cognitive behavior therapy for early psychosis: a comprehensive review of individual vs. group treatment studies.

Several recent studies of individually administered cognitive behavior therapy (CBT) for early psychosis have reported only modest treatment benefits. The purpose of the current study was to review the literature to determine how outcomes of group CBT differ from outcomes of individually administered CBT among early cases. Our findings suggest that group CBT for early psychosis may be a more effective modality for this group of patients. We speculate that patients' uncertainty about illness in general may impair the effectiveness of individually administered CBT for early cases and that group CBT may be more effective for these young patients by better addressing those factors with the aid of peer-to-peer interactions, identification, and modeling.
