Introduction

Social cognition is a complex construct that refers to the functions required to understand other people's mental states and behavior. In people with schizophrenia, social cognition deficits account for a proportion of variance in functional outcome, independent of symptomatology. However, the relationships among social cognition, neurocognitive functioning and functional outcome are still unclear. Previous investigations had several limitations including small sample size, heterogeneous and limited measures of social cognition and neurocognitive functions.

Aims

Within the study of the Italian Network for Research on Psychoses, we investigated factors influencing outcome in patients with schizophrenia and their unaffected relatives. Psychopathology, including depression, neurocognition, social cognition and outcome were assessed using instruments designed to overcome some of the previous limitations.

Methods

Structural equation modeling was used to test direct and indirect effects of neurocognition, social cognition and functional capacity on vocational and interpersonal functioning. Tests of facial emotion recognition, emotional intelligence and theory of mind were included to assess social cognition. The MATRICS Consensus Cognitive Battery (MCCB) was used to investigate neurocognition.

Results

In both subjects with schizophrenia and their first-degree relatives, social cognition was found to be independent of negative symptoms and to have a direct impact on outcome. Neurocognition was a predictor of functional capacity and social cognition, which both mediated its impact on outcome. Social cognition was independent of functional capacity and negative symptoms.

Conclusions

Better understanding of how neurocognitive dysfunction and social cognition deficits relate to one another may guide efforts toward targeted treatment approaches.
