Social cognitive impairments in first episode psychosis

BackgroundSocial cognition is a complex phenomenon involving several distinct processes. Numerous studies have shown that individuals with schizophrenia are largely impaired on this domain of cognition. However, most have focused on a single aspect of social cognition, namely “theory of mind” and/or included patients with long standing illness.ObjectiveThe main objective of the present study was to identify social cognition deficits in first episode of schizophrenia spectrum psychosis using a case control design and a comprehensive assessment that allowed the exploration of several dimensions of this phenomenon.Subjects36 patients with a first episode of psychosis and 25 healthy controls participated in this study.MaterialMeasures of social cognition included the Hinting Task and the Four Factor Test of Social Intelligence.ResultsSignificant group differences were found on both tasks, but the Four Factor Test of Social Intelligence revealed a stronger group effect and the effects observed remained significant once IQ was covaried. Social cognition did not show any correlations with level of symptoms.ConclusionSocial cognition deficits are present during the first episode of psychosis. These impairments do not seem to be a consequence of group differences in overall intellectual functioning and are likely to be state-independent.
