摘要： 目的 以自杀未遂者的自杀行为特征为依据进行聚类分析,识别自杀未遂者的不同类型,并探究各类型自杀未遂者的特征差异。 方法 运用面对面访谈的方式收集408例急诊或住院自杀未遂者的人口学、社会心理学和自杀未遂行为特征的数据。采用二阶聚类法进行聚类分析。 结果 408例自杀未遂者被分为两种类型:231例(56.62%)纳入冲动组,表现为自杀意图低、致死性低、冲动性强;177例(43.38%)纳入计划组,表现为自杀意图高、致死性高、多有自杀未遂史。与冲动组相比,计划组自杀未遂者年龄更大(P=0.003),抑郁、绝望水平更高(P<0.001),患精神障碍的比例更高(P<0.001)。 结论 两组自杀未遂者的特征明显不同,应分别采取有针对性的预防及干预措施。

Abstract: Objective To classify and explore the characteristics of different types of suicide attempters in terms of the suicidal behaviors. Methods The demographic characteristics, psychosocial factors, and details of suicide attempts of 408 medically serious suicide attempters in rural areas of Shandong Province were collected by face-to-face interviews. Cluster analysis was performed using the two-step method. Results The suicide attempters fell into two types: 231(56.62%)in the impulsive cluster, characterized by low suicide intent, low lethality, and high impulsiveness; 177(43.38%)in the well-planned cluster, characterized by high suicide intent, high lethality, and more histories of attempted suicide. The well-planned group was associated with older age(P=0.003), mental illness(P<0.001), and higher depression and hopelessness(P<0.001). Conclusion Cluster analysis extracts two distinct groups of suicide attempters showing different patterns of suicidal behaviors. Targeted prevention strategies should be formulated for different groups.
