Symptom correlates of facial emotion recognition impairment in schizophrenia.

ABSTRACT

BACKGROUND: The ability to facial emotion recognition (FER), a key component of socioemotional competence, is often impaired in schizophrenic disorders. The purpose of the present study was to examine the relationship between emotion recognition performance and symptoms in a group of patients with schizophrenia spectrum disorders. SAMPLING AND METHODS: Seventy-nine patients meeting DSM-IV-TR criteria for schizophrenia, schizophreniform disorder and schizoaffective disorder were assessed by the Positive and Negative Syndrome Scale and a FER task. In schizophrenia patients and healthy control subjects, FER performance was compared. In order to avoid a possible confounding role of cognitive impairment, we carried out partial correlations corrected for an index of global cognition. RESULTS: Patients performed worse than a healthy control group on all negative emotions. Partial correlations showed that cognitive/disorganized symptoms correlated with a worse performance in the FER task, whereas no correlations were found with positive, negative, excitement and depressive symptoms. CONCLUSIONS: Our findings support that in schizophrenia FER impairment is specific for negative emotions and that there is a relationship between this deficit and cognitive/disorganized symptoms, regardless of the general cognitive level.
