Metacognitive and social cognition approaches to understanding the impact of schizophrenia on social quality of life.

While some studies view metacognition and social cognition as representing the same phenomenon, others suggest that they represent distinctive sets of abilities that are related to different outcomes. The current study used a cross-sectional design that includes samples of persons with schizophrenia (N=39) and healthy individuals (N=60) to further explore the distinction between social cognition and metacognition and their associations with social quality of life. The Face Emotion Identification Task (FEIT), Faux-Pas Task, Indiana Psychiatric Illness Interview (IPII), Metacognition Assessment Scale - Abbreviated (MAS-A), and Social Quality of Life Scale were administrated to all participants. Correlations, t-tests and regressions were conducted. Results showed that persons with schizophrenia performed more poorly on all measures than healthy controls. Social cognition and metacognition measures were related for the combined total sample, but only a few associations were found among both sub-samples. A diagnosis of schizophrenia and metacognitive capacity, but not social cognition, predicted social quality of life. Self-reflectivity had a negative relationship to social quality of life while understanding of others' minds had a positive relation to social quality of life. The current study provides evidence that many with schizophrenia experience deficits in both social cognition and metacognition and that those deficits may be distinct and have different kinds of relationships with social quality of life. Clinical implications include the need to emphasize narrative aspects of psychotherapy in order to promote metacognition.
