Social functioning in individuals at clinical high risk for psychosis.
Poor social functioning is a hallmark of schizophrenia. The purpose of this study was to examine social functioning in individuals at clinical high risk for psychosis. Social functioning was assessed in a sample of 86 clinical high risk (CHR) individuals and compared to that of 50 first-episode of psychosis (FE) subjects, 53 multi-episode schizophrenia subjects (ME) and 55 non-psychiatric controls (NPC). Subjects were assessed on the Social Functioning Scale (SFS), the Role Functioning subscale of the Quality of Life Scale (QLS-role), and the premorbid functioning scale. On the SFS, the CHR group did not differ significantly from the FE and ME groups and all were impaired relative to the NPCs. On QLS-role, the CHR group performed significantly better than the ME patients and significantly worse than NPCs. CHR subjects did not differ from patients in terms of premorbid functioning. This study demonstrates that even at the pre-psychotic phase of the illness, these young people are demonstrating significant deficits in social functioning, supporting that social deficits are present long before the onset of psychotic symptoms.
