Metacognition and social function in schizophrenia: associations of mastery with functional skills competence.

Research has suggested that many with schizophrenia experience deficits in the ability to form complex ideas about their own mental states and those of others and to use that in the service of responding to the challenges of both everyday life and the illness itself. Preliminary evidence suggests that deficits in such metacognitive and social cognitive functions are a predictor of function independent of other aspects of schizophrenia. In this study, we explored whether the domain of metacognition that reflects the ability to form knowledge about one's own mental states and those of others and to use that knowledge to respond to psychological challenges, known as Mastery, was related to performance on a test of functional skills competence. Participants were 40 adults with schizophrenia spectrum disorders in a non-acute phase of illness. Metacognitive Mastery was assessed using the Metacognitive Assessment Scale (MAS) and skills competence was assessed using the UCSD Performance-Based Skills Assessment Battery (UPSA). Symptoms were also assessed using the Positive and Negative Syndrome Scale and executive function was assessed with the Wisconsin Card Sorting Test. Correlations revealed a significant relationship between Mastery and the UPSA comprehension/planning subscale. This relationship persisted even after controlling for symptoms and executive function in a regression analysis. Results are consistent with the possibility that the ability to use metacognitive knowledge to respond to daily life is uniquely linked with certain forms of functional competence among persons with schizophrenia, independent of the effects of illness severity.
