Group CBT for Early Psychosis—Are There Still Benefits One Year Later?

Abstract

Our team recently conducted a randomized controlled trial comparing group cognitive behavior therapy for psychosis (CBTp) to group social skills training for symptom management and a wait-list control group, for early psychosis. The results at post-therapy and six months provided considerable empirical support for the efficacy of the group CBTp. The results of the one-year follow-up are described here. Given the high attrition rates, mostly in the comparison and control conditions, imputations were not possible, so that only the results of those having completed more than 50% of the group CBTp are presented. Significant improvements at 12 months were found for social support and insight. Negative symptoms remained low, whereas positive symptoms went back to pre-therapy levels. Challenges regarding attrition with this clientele are discussed.
