Effectiveness of metacognitive interventions for mental disorders in adults – a systematic review and meta‐analysis (METACOG)

AbstractWe evaluated the effectiveness and acceptability of metacognitive interventions for mental disorders. We searched electronic databases and included randomized and non ‐randomized controlled trials comparing metacognitive interventions with other treatments in adults with mental disorders. Primary effectiveness and acceptability outcomes were symptom severity and dropout, respectively. We performed random‐effects meta‐analyses. We identified Metacognitive Tr aining (MCTrain), Metacognitive Therapy (MCTherap) and Metacognition Reflection and Insight Therapy (MERIT). We included 49 trials with 2,609 patients. In patients with schizophrenia, MCTrain was more effective than a psychological treatment (cognitive remediation, SMD=‐0.39). It bordered signific ance when compared to standard or other psychological treatments. In a post hoc analysis, across all studies, the pooled effect was significant (SMD=‐0.31). MCTrain was more effective than standard treatment in patients with obsessive‐compulsive disorder (SMD=‐0.40). MCTherap was more effectiv e than a waitlist in patients with depression (SMD=‐2.80), posttraumatic stress disorder (SMD=‐2.36) and psychological treatments (cognitive behavioral) in patients with anxiety (SMD=‐0.46). In patients with depression MCTherap was not superior to psychological treatment (cognitive behavioral) . For MERIT, the database was too small to allow solid conclusions. Acceptability of metacognitive interventions among pa...
