[Social cognition in schizophrenia. Mentalising and psychosocial functioning].

Schizophrenia is characterised by impaired psychosocial functioning that is often already present in early stages of the disorder. Recent studies suggest that social-cognitive deficits such as mental perspective-taking or mentalising are causally linked with poor social functioning in schizophrenia. This article reviews the evidence for such an association. Findings imply the integration of social-cognitive training in a treatment concept for schizophrenia. However, to date it remains elusive whether or not the impact of improved social cognition on psychosocial functioning is stable over prolonged periods of time. To answer this open question requires longitudinal studies that are currently unavailable.
