| 摘 要： | 目的 探讨中学生童年创伤和失眠与非自杀性自伤(NSSI)的关系，以及失眠在中学生童年创伤与非自杀性自伤间的中介效应。方法 采用童年创伤问卷、失眠严重程度指数、青少年自我伤害问卷对广西南宁市三所中学的学生进行抽样调查，采用SPSSAU 21.0进行统计分析。结果 在3442名中学生中，NSSI的检出率为31.93%，在年级、性别、家庭经济状况三方面NSSI检出率差异有统计学意义（x2=38.841，P<0.001；x2=10.524，P=0.001；x2=16.486，P<0.001）；伴NSSI组童年创伤总分及各维度得分、失眠总分高于不伴NSSI组（F值分别为249.029、138.256、65.656、23.316、90.787、279.991、386.503，均P<0.001）；童年创伤与NSSI和失眠均呈正相关（r=0.126～0.328，P<0.010；r=0.113～0.307，P<0.010），失眠与NSSI呈正相关（r=0.355，P<0.010），控制人口学资料后相关性仍然存在；控制人口学资料后，童年创伤对NSSI的总效应为0.514（95%CI:0.466～0.562），对失眠的直接效应为0.183（95%CI:0.164～0.202），失眠对NSSI的直接效应为0.634（95%CI:0.552～0.715）；失眠在童年创伤与NSSI间的中介效应为0.116（95%CI:0.081～0.153），说明失眠在中学生童年创伤与NSSI间起部分中介作用，中介效应占总效应的比例为22.568%。结论 童年创伤既可以直接影响中学生非自杀性自伤行为，也可以通过失眠的中介效应间接影响中学生非自杀性自伤行为。

| Abstract: | Objective To explore the relationship between childhood trauma, insomnia and non-suicidal self-injury (NSSI) in middle school students and to explore the mediating effect of insomnia between childhood trauma and NSSI in middle school students. Methods The Childhood Trauma Questionnaire, Insomnia Severity Index, and adolescent self-injury questionnaire were used to conduct a sample survey on students from three middle schools in Nanning, Guangxi. SPSSAU21.0 was used for statistical analysis. Results Among the 3 442 middle school students, the detection rate of NSSI was 31.93%, and there were significant differences in the detection rate of NSSI in terms of grade, gender, and family economic status (x2=38.841, P<0.001; x2=10.524, P=0.001; x2=16.486, P<0.001). The total score of childhood trauma, the scores of each dimension and the total score of Insomnia in the group with NSSI were higher than those in the group without NSSI (F-values of 249.029, 138.256, 65.656, 23.316, 90.787, 279.991, 386.503, respectively; all P<0.001). Childhood trauma were positively correlated with NSSI and Insomnia (r=0.126-0.328, P<0.001; r=0.113-0.307, P<0.010), and total insomnia scores were positively correlated with NSSI (r=0.355, P<0.010). Correlation persisted after controlling for demographic data. After controlling for demographic data, the total effect of childhood trauma on NSSI was 0.514 (95%CI: 0.466-0.562), the direct effect of childhood trauma on insomnia was 0.183 (95%CI: 0.164-0.202), and the direct effect of insomnia on NSSI was 0.634 (95%CI:0.552-0.715). The mediating effect of insomnia between childhood trauma and NSSI was 0.116 (95%CI: 0.081-0.153), indicating that insomnia played a partial mediating role between childhood trauma and NSSI in middle school students. And the mediating effect accounted for 22.568% of the total effect. Conclusion Childhood trauma can directly affect the non-suicidal self-injury behavior of middle school students, but can also indirectly affect the non-suicidal self-injury behavior of middle school students through the mediating effect of insomnia. |
