Detailed Description

The overall aim of this study was to develop a Meta cognitive group intervention in order to apply it and to understand and distinguish the components that influence participation among people with schizophrenia. The specific objectives were to:

1. Improve participation by increasing the effectiveness of cognitive strategy use and teaching clients to independently review performance and to examine the strategy's effectiveness.

2. Compare the use of cognitive strategies between participants with schizophrenia and their matched controls following the Meta cognitive group intervention and to correlate the cognitive strategies use and participation following the Meta cognitive group.

3. Examine whether symptoms moderate the association between metacognitive outcomes and participation among people with schizophrenia following the Meta cognitive group.
