Study summary

The combination of the Integrated Psychological Therapy and Metacognitive Training in individuals with schizophrenia and treatment resistant schizophrenia.

Is it effective and efficacious?

Read the detailed description

Individuals with schizophrenia and treatment resistant schizophrenia will participate on a group cognitive behavioral therapy and rehabilitation, in which Integrated Psychological Therapy and Metacognitive Training are going to be implemented. The therapy will last 60 biweekly sessions. This is a non randomized trial.

Speed of processing, working memory, verbal memory, visual memory, reasoning and problem solving, social cognition, symptoms, functional outcome and recovery will be evaluated before, after therapy and in a 6 months follow up.

MCCB, Social Perception Scale, the Greek Test for verbal memory, PANSS, WHO DAS 2. 0 (Greek), PSYRAT and the Recovery Assessment Scale will be used ih this study.
