BACKGROUND AND OBJECTIVES: Controversial findings exist in the literature regarding the state- and trait-like characters of social cognition in schizophrenia. In order to explore the relationship of social cognition with symptom severity in the present study, Theory of mind (ToM) and emotion recognition were tested in an acute phase and later in a clinically stable phase in patients. METHODS: ToM and emotion recognition abilities were examined by using the Reading the Mind in the Eyes Test (RMET) and the Ekman 60 Faces Test (FEEST) in 43 patients with schizophrenia and 41 healthy controls. Research diagnoses were based on SCID interviews. Symptom severity in patients was assessed by the Positive and Negative Syndrome Scale (PANSS). RESULTS: ToM and emotion recognition deficits improved in the clinically stable phase compared to relapse, but were still found to be impaired compared to healthy controls. Negative symptom severity showed strong correlation with emotion recognition and ToM at both visits. CONCLUSIONS: Both ToM and emotion recognition fluctuated together with symptom severity, which confirmed the "state-like" component of these abilities. Our results, taken together with the findings of previous investigations show that social cognition deficits in schizophrenia have both state-like and trait-like components.
