Childhood Trauma, Psychological Distress, and Non-Suicidal Self-Injury among Secondary school students

• 摘要：目的 探讨中学生童年创伤、心理困扰(情绪症状与睡眠问题)与非自杀性自伤行为(NSSI)之间的关系,以及心理困扰在童年创伤与NSSI间的中介作用。方法 2024年10月至2025年3月,采用方便抽样法选取泸州市5所中学的16 310名初、高中学生进行在线问卷调查,使用儿童期创伤问卷、广泛性焦虑量表、抑郁筛查量表、失眠严重程度指数及青少年非自杀性自伤行为评定问卷进行测评。采用SPSS 22.0和 R软件进行统计分析,通过Bootstrap法检验心理困扰的中介效应。结果 中学生NSSI行为检出率为20.40%,其中偶发NSSI为16.68%,反复NSSI为3.72%。童年创伤、心理困扰与NSSI行为两两呈显著正相关。心理困扰在童年创伤与NSSI之间起部分中介作用,中介效应占比为17.10%。结论 童年创伤可直接影响中学生NSSI行为的发生,也可通过心理困扰间接发挥作用。心理困扰在童年创伤与NSSI间起部分中介作用,提示在NSSI防控中应重视心理困扰(特别是情绪与睡眠问题)的早期识别与干预。

  Abstract: Objective To explore the association between childhood trauma, psychological distress (including emotional symptoms and sleep disturbances), and non-suicidal self-injury (NSSI) behaviors in secondary school students, and to investigate the mediating role of psychological distress in the relationship between childhood trauma and NSSI. Methods From October 2024 to March 2025, 16,310 students from five secondary schools in Luzhou City were recruited via convenience sampling for an online survey. Participants completed the Childhood Trauma Questionnaire (CTQ), Generalized Anxiety Disorder Scale (GAD-7), Patient Health Questionnaire (PHQ-9), Insomnia Severity Index (ISI), and the Adolescent Non-Suicidal Self-Injury Assessment Questionnaire. Statistical analyses were conducted using SPSS 22.0 and R software, and the mediating effect of psychological distress was tested using the bootstrap method. Results The prevalence of NSSI among participants was 20.40%, with occasional and repetitive NSSI accounting for 16.68% and 3.72%, respectively. Childhood trauma, psychological distress, and NSSI were significantly positively correlated. Mediation analysis indicated that psychological distress partially mediated the relationship between childhood trauma and NSSI, accounting for 17.10% of the total effect. Conclusions Childhood trauma is associated with NSSI in secondary school students both directly and indirectly through psychological distress. Since psychological distress partially mediates the relationship between childhood trauma and NSSI, early identification and intervention targeting emotional and sleep disturbances are crucial for the prevention and management of NSSI.
