Predictors of social functioning in patients with higher and lower levels of reduced emotional experience: Social cognition, social competence, and symptom severity

Background: Deficits in social functioning in schizophrenia are primarily predicted by negative symptoms, social cognition deficits, and social skills deficits. Here we examine those predictive variables across variations in the severity of reduced emotional experience. We hypothesized that in patients with high symptom severity, factors such as social cognition would have reduced importance for predicting social outcomes. Methods: Participants with schizophrenia (n = 312) were tested using five different measures of social cognition. Performance-based assessments and clinical ratings of reduced emotion experience were used to assess social competence. High contact informants rated interpersonal functioning and social acceptability of behavior, while unaware of other patient data. Patients were divided into higher and lower reduced emotional experience using previously validated criteria. Results: 33% of the patients had at least moderate symptoms of reduced emotional experience. Patients with greater severity had more social functioning impairment, but not poorer social competence and social cognition. In the patients with lower severity, social cognition accounted for 9% of the variance in interpersonal functioning, while in patients with higher severity, social cognition did not predict any variance. In the patients with lower severity, social cognition accounted for 4% of the variance in social acceptability of behavior, while in patients with higher severity, social cognition also did not predict any variance.
