Abstract：
This study delves into the correlation between childhood trauma and non-suicidal self-injury (NSSI) behaviors among high school students. Additionally, it examines the mediating role of stress perception and the moderating role of the teacher-student relationship in this association. A questionnaire survey was administered to 1,329 high school students in Yunnan Province to assess childhood trauma, NSSI behaviors, and stress perception. Firstly, the survey revealed a 12% prevalence of NSSI, with girls exhibiting a higher occurrence compared to boys (OR = 0.413, 95% CI: 0.280-0.609). Secondly, childhood trauma emerged as a significant predictor of NSSI behavior, irrespective of gender or whether the individual was an only child (r = 0.17, P < 0.01). Thirdly, stress perception functioned as a mediator in the relationship between childhood trauma and NSSI among high school students (t = 4.65, P < 0.01). The mediation effect occupies 26.56% of the total effect. Furthermore, the teacher-student relationship moderated the mediating effect of stress perception on the link between childhood trauma and NSSI (β = 0.0736, P < 0.01). Notably, individuals with strong teacher-student relationships exhibited a significant elevation in stress perception upon exposure to childhood trauma. The findings of this study support a moderated mediation model in the association between childhood trauma and NSSI, suggesting profound implications for the development of targeted interventions and prevention strategies among high school students.
摘要：
本研究探讨了高中生的儿童期创伤与非自杀性自伤（NSSI）行为之间的相关性。此外,它研究了压力感知的中介作用和师生关系在这种关联中的调节作用。对云南省1,329名高中生进行问卷调查，评估儿童期创伤，NSSI行为，和压力感知。首先,调查显示NSSI的患病率为12%，女孩的发生率高于男孩（OR=0.413，95％CI：0.280-0.609）。其次,童年创伤是NSSI行为的重要预测因子，不论性别或是否为独生子女(r=0.17,P<0.01)。第三，应激感知在高中生儿童期创伤与NSSI的关系中起中介作用(t=4.65,P<0.01)。调解效应占总效应的26.56%。此外，师生关系调节了应激感知在儿童期创伤与NSSI之间的中介作用（β=0.0736，P<0.01）。值得注意的是,具有牢固的师生关系的个体在暴露于童年创伤后表现出压力感知的显着提高。这项研究的结果支持儿童期创伤与NSSI之间的相关性的适度调解模型，对高中生制定有针对性的干预措施和预防策略具有深远的意义。
