Relationships between neurocognition, social cognition and functional outcome in schizophrenia

Abstract

IntroductionThe inter-relationships of neurocognition, social cognition, residual psychopathology and real-life functioning are poorly understood. A large multicenter study was carried out by the Italian Network for Research on Psychoses to model relationships between neurocognitive deficits, psychopathology and real-life functioning, taking into account the role of functional capacity and social cognition.MethodsA structural equation model was used to investigate direct and indirect effects of neurocognition and psychopathology on real-life functioning. Social cognition and functional capacity were modeled as mediators.ResultsIn 921 patients with schizophrenia, neurocognition had both direct and indirect effects, through functional capacity and social cognition, on real-life functioning. Neurocognition predicted to a large extent social cognition on which depression and disorganization had a modest effect. Social cognition showed a significant direct impact on real-life functioning.ConclusionOur results support a strong link between neurocognition and functional outcome, independent of psychopathology. Social cognition accounted for unique incremental variance in real-life functioning.Disclosure of interestThe authors have not supplied their declaration of competing interest.
