Effect of meta-cognitive training in the reduction of positive symptoms in schizophrenia

Metacognitive training (MCT), a variant of Cognitive Behaviour Therapy, is a recently developed therapeutic method that targets active positive symptoms, primarily delusions. It translates basic research related to cognitive biases behind these symptoms into a training procedure for schizophrenia patients. To see the effectiveness of MCT a total of sixteen recently admitted schizophrenia patients were randomly divided into two groups. One group underwent treatment as usual (TAU) and the other group underwent MCT plus TAU. The MCT group showed steeper decline in positive symptoms with medium to large effect sizes. Findings are discussed in the light of their practical implications.
