A practice-oriented review on effectiveness of metacognitive training (Mct) for psychosis

This review contains a practical overview of the metacognitive training for psychosis (MCT); practical issues concerning the use and administration of the training are presented. MCT consists of two cycles of 8 modules (plus two additional modules). Reviews and meta-analyses have demonstrated the feasibility and high acceptance by patients. Medium effect sizes are reported with regard to reduction of psychotic symptoms. Effects on jumping to conclusions are mixed. Largest effects are reported when patients have more general, and mild to moderate psychotic symptoms, and when the two full cycles are completed. Strengths and limitations are discussed, and recommendations for use and future research are presented. MCT is a meaningful addition to the treatment of psychosis.
