初中学生家庭功能对自杀相关行为的影响:抑郁的中介作用

Effect of Family Function on Suicide-Related Behaviors of Junior Middle School Students: The Mediating Effect of Depression

  • 摘要:
      目的   了解目前初中学生自杀相关行为的流行情况,探索抑郁在家庭功能影响自杀相关行为中的中介作用。
      方法   使用青少年危险行为监测问卷(YRBSS)自杀相关问题、儿童家庭功能评定量表(C-FAI)、流调中心儿童抑郁量表(CES-DC)对成都市三所中学2572名初中学生进行面对面调查,利用结构方程模型进行分析。
      结果   受访的中学生自杀相关行为检出率为26.01%,其中,自杀意念、自杀计划、自杀未遂的检出率依次为24.38%、13.49%和10.77%。抑郁在家庭功能对自杀相关行为的影响中起部分中介作用,直接效应值为0.170(95%CI:0.117~0.218,P<0.001),间接效应值为0.205(95%CI:0.176~0.234,P<0.001),中介效应值占总效应值的54.67%。
      结论   家庭功能低下会增加中学生自杀相关行为的发生风险,这一作用大部分是通过影响儿童心理健康来实现的。改善家庭功能,不仅能改善儿童心理状况,还能减少自杀相关行为。

     

    Abstract:
      Objective  To examine the prevalence of suicide-related behaviors among junior middle school students, and to explore the mediating role of depression in the relationship between suicide-related behaviors and family function.
      Methods  A total of 2572 junior middle school students from three middle schools in Chengdu were interviewed face-to-face by using suicide-related items from Youth Risk Behavior Surveillance System (YRBSS), Chinese Family Assessment Instrument (C-FAI), and Center for Epidemiologic Studies Depression Scale for Children (CES-DC). The mediating role of depression was analyzed with structural equation model.
      Results  The prevalence of suicide-related behaviors was 26.01% among the respondents. The prevalence of suicide ideation, suicide plan and suicide attempt were 24.38%, 13.49% and 10.77%, respectively. Depression played a partial mediating role in how family function impacted on suicide-related behaviors, presenting a direct effect value of 0.170 (95% CI: 0.117-0.218, P<0.001) and an indirect effect value of 0.205 (95% CI: 0.176-0.234, P<0.001), with the mediating effect accounting for 54.67% of the total effect.
      Conclusion  Poor family function may increase the risk of suicide-related behaviors, and this effect is produced mostly through the impact on children's mental health. Improving family function will not only improve children's psychological status, but also reduce suicide-related behaviors.
