Gender differences in empathy and clinical symptoms in chronic schizophrenia patients: a large sample study based on a Chinese Han population.

Background: Empathy is social cognition and reduced empathy in schizophrenia (SCZ) has been noted; however, whether there are gender differences in empathy remains unclear. Therefore, the purpose of this study was to explore this issue by examining a large sample of the population with SCZ.

Methods: We recruited 987 SCZ patients (M/F = 638/349). The empathy was assessed by The Interpersonal Reactivity Index (IRI). The Positive and Negative Syndrome Scale (PANSS) was adopted to assess their clinical psychiatric symptoms and their ability to recognise the facial emotions of others was assessed by the Pictures Of Facial Affect (POFA).

Results: Female SCZ patients had higher IRI total score than male patients. In male patients, Pearson correlation analysis showed that empathy was negatively correlated with PANSS total score and negative symptom subscale scores, but positively correlated with anger identification. In female patients, IRI total score was negatively correlated with PANSS total score as well as its positive and negative symptom subscale scores (all p < 0.05).

Conclusion: There are gender differences in the empathy of SCZ patients, with female patients having greater empathy and a correlation with their clinical symptoms. This gender difference may provide potential clinical value for the treatment of SCZ.KEY POINTSFemale SCZ were more likely to empathise than males;Female patients had more severe clinical symptoms than males;There were gender differences in the association between certain specific clinical presentations and empathy.In future studies, it may be useful to investigate gender differences in schizophrenia empathy for the diagnosis and treatment of the disorder.
