Association between empathy and clinical symptoms in chronic schizophrenia: A large sample study based on Chinese Han population

Abstract Background In patients with schizophrenia, clinical symptoms and cognitive impairment are its core features, both of which have a significant impact on the prognosis and functional outcome. Empathy, as an important social cognition, has been found to be associated with the clinical symptoms in schizophrenia, but the conclusions on this issue are inconsistent. Therefore, this study will continue to explore it through a large sample of inpatients with chronic schizophrenia in the Chinese Han population. Methods We obtained the sociodemographic characteristics of 987 inpatients, measured their clinical symptoms using the Positive and Negative Syndrome Scale (PANSS), and assessed their self-reported empathy using the Interpersonal Reactivity Index (IRI). The factor score for negative symptoms (FSNS) of PANSS was additionally calculated. Results Correlation and linear regression analysis showed that patients' PANSS scores were widely correlated with their IRI scores. In particular, the negative symptoms of patients were significantly correlated to IRI total score (r = −0.131, p  Conclusions Our results indicated that clinical symptoms, especially negative symptoms, were closely related to their current empathy in patients with schizophrenia, suggesting that the severity of clinical symptoms may be a powerful factor in predicting social cognition such as empathy of schizophrenia.
