In this study, demographic and clinical characteristics of individuals with schizophrenia in a Chinese rural community who had attempted suicide at some time in their lives and those who had not made a suicide attempt were compared. Among individuals with schizophrenia, subjects with (n = 38) and without (n = 472) a lifetime history of suicide attempt were assessed with the Present State Examination. The results indicate that attempters had a significantly younger age, higher level of education, higher rate of lifetime depressed mood and hopelessness, and a larger number of positive symptoms than patients without suicide attempts. The logistic regression models also indicated that hopelessness, the number of positive symptoms and age were the most important predictors. Early interventions focusing on reducing hopelessness and controlling positive symptoms may help reduce the risk of suicide attempts among patients with schizophrenia.
在本研究中，对中国农村社区中曾有过自杀未遂经历的精神分裂症患者和未曾有过自杀未遂经历的患者的人口统计学和临床特征进行了比较。在精神分裂症患者中，对有过自杀未遂经历（n = 38）和没有自杀未遂经历（n = 472）的受试者进行了现状检查评估。结果表明，与没有自杀未遂经历的患者相比，自杀未遂者年龄显著更小、受教育程度更高、终生抑郁情绪和绝望感发生率更高，且阳性症状数量更多。逻辑回归模型还表明，绝望感、阳性症状数量和年龄是最重要的预测因素。聚焦于降低绝望感和控制阳性症状的早期干预可能有助于降低精神分裂症患者自杀未遂的风险。
