Study summary

The purpose of this study is to determine whether modules of Metacognitive Training: Jumping to Conclusions and To empathize... are effective in the treatment of patients with schizophrenia. Also it was investigated whether these modules have specific impact on cognitive biases severity.

Read the detailed description

Investigators employ randomized controlled trial design. Patients in ward were recruited for the study in three waves. In each wave patients were assessed pre-intervention, then randomly allocated in one of three groups: with modules of Metacognitive Training or control group. Then patients were assessed post-intervention.
