Background: The relationship between neurocognition and symptomatology in people with schizophrenia has been established. The present study examined whether social cognition could mediate this relationship.Methods: There were 119 participants (58 people with paranoid schizophrenia and 61 healthy controls) participated in this study. Neurocognition was assessed by Raven's Progressive Matrices Test, the Judgment of Line Orientation Test, and the Tower of London Test. Psychiatric symptoms in people with schizophrenia were assessed by the Positive and Negative Syndrome Scale. Social cognition was measured by the Faux Pas Test, the " Reading the Mind in the Eyes" Test, and the Interpersonal Reactivity Index.Results: Results were consistent with previous findings that neurocognition and social cognition were impaired in the clinical participants. A novel observation is that social cognition significantly mediated the relationship between neurocognition and symptomatology.Conclusions: These findings suggest that neurocognitive deficits predispose people with schizophrenia to worse psychiatric symptoms through the impairment of social cognition. Findings of the present study provide important insight into a functional model of schizophrenia that could guide the development of cost-effective interventions for people with schizophrenia.
