摘要：Negative symptoms and depression persist in one third of patients with schizophrenia. Previous studies suggested that depression has more impact on self-perceived compared to observer-rated social functions. Reduced emotional experience, a subdomain of negative symptoms, predicts social functioning deficits, although its role in self-assessment is unclear. We examined depression and reduced emotional experience and self-reports and informant ratings of social functioning and social cognitive abilities in 135 patients with schizophrenia. Discrepancies between sources were used to index the accuracy and bias in self-assessment. Less severe depression was associated with self-reports of reduced impairments in social functioning and better social cognitive abilities. Reduced emotional experience was related to informant ratings and self-reports of social functioning. Neither reduced emotional experience nor depression was correlated with discrepancies between sources, despite the bias of patients with lower depression to report that they were higher functioning and more competent. These findings suggest that patients with schizophrenia make global judgments about functioning based on current mood states. There was minimal association between the depression severity and the accuracy of self-assessment, despite positive biases associated with lower depression severity. The determinants of accuracy and bias in self-assessment requires more detailed examination and subdivision of patients based on their depression.
