Abstract

OBJECTIVES: Previous studies have shown that cognitive impairment plays a key role in suicide, an important factor leading to premature death in schizophrenia (SCZ) patients. Empathy has received extensive attention recently; however, the relationship of empathy with suicide in schizophrenia is still unknown. The main aim of this study was to investigate the prevalence of suicide attempts and its association with empathy and other characteristics in Chinese chronic SCZ patients.

METHODS: The suicide attempt data, together with demographic characteristics and clinical variables were collected from 627 chronic inpatients with schizophrenia. We utilized the Positive and Negative Syndrome Scale (PANSS) for the psychopathological symptoms, and the Interpersonal Reactivity Index (IRI) for affective and cognitive empathy in this study.

RESULTS: We found a suicide attempt rate of 11.3% in chronic SCZ patients. Compared to non-attempters, suicide attempters were more likely to be women, had younger age and higher education level, as well as higher positive symptoms and depressive factor score, but lower negative symptoms of PANSS (all p < .05). Moreover, after controlling the confounding factors, suicide attempters scored higher in Personal Distress subscale of IRI (F_{1, 455} = 5.446, p = .020) than non-attempters.

CONCLUSIONS: The prevalence of suicide attempt is high in chronic SCZ patients. Its risk factors include some demographic and clinical variables. Moreover, suicide attempters experienced stronger personal distress, suggesting that stronger empathy may be a risk factor of suicide.
