摘要
目的比较生活事件量表在自杀研究中不同信息来源下的一致性。方法纳入104例自杀未遂和147例自杀死亡案例。每个案例都分别由1名家属和1名亲友报告案例对象在自杀行为前经历过的生活事件,自杀未遂者本人也报告自己在自杀行为前经历过的生活事件,用生活事件量表进行评估。采用Kappa值、组内相关系数(intraclass correlation coefficient,ICC)等指标评估生活事件量表的不同信息来源之间的一致性。结果自杀未遂者本人和2名知情人报告的夫妻关系、自身患病、家庭关系、家人去世等类型生活事件的一致性接近中等及以上水平(Kappa≥0.39),而本人与知情人之间慢性压力总分及急性应激强度得分的一致性较低(ICC为0.11~0.24)。自杀者的2名知情人在配偶去世、工作学习、自身患病类生活事件上的一致性达到中等及以上水平(Kappa≥0.49),慢性压力总分一致性一般(ICC=0.47)。结论在自杀研究中运用结构化的生活事件量表从知情人处获得自杀者或未遂者的生活事件信息比较可靠。
Objective To conduct concordance test on L/fe Event Scale reported by different informants and the suicide-attemptcrs themselves in Chinese suicide research. Methods In this retrospective study, 104 attempted suicide cases and 147 suicide cases were included. Each case had two informants. One was family member, and the other was associate （friends, neighbors, etc.）. Suicide attempters （only for attempted suicide cases） were also interviewed by qualified psychiatrists. Life Event Scale was administered to each respondent to obtain life events experienced by the case before the suicidal behavior. Kappa and Intraclass Correlation Coefficient （ICC） were used to compare the suicide attempters＇ self-reports with two informants＇ reports, and to present the concordance of two informants＇ reports for suicides. Results For attempted suicide group, agreements were nearly moderate or better for life events on marital relation, physical illness, family relation, love, birth or death of family members （KappaS0.39）; Proxy-based chronic stress and acute stress scores were significantly lower than subject-reports （ICC： 0.11-0.24, P〈0.01）. For suicide group, the agreements between the two informants＇ reports were moderate or better on death of spouse, work/study or physical illness （Kappa ≥0.49）; The agreement for chronic stress score was fair （ICC=0.47）. Conclusions The results have demonstrated that proxy-based data on life events are valid if structured and objective scales are used.
