中文摘要:

      摘要：背景 非自杀性自伤（NSSI）行为已成为影响青少年身心健康的全球公共卫生问题。经验回避模型指出，童年创伤会通过情绪失调导致NSSI行为。然而，现有研究多局限于单一的心理或社会因素，缺乏对两者交互作用的综合探讨。目的 探究童年创伤与青少年NSSI行为之间的关系，分析情绪失调的中介作用及社交焦虑的调节作用。方法 使用一般资料调查表、青少年非自杀性自伤行为功能评估量表、童年期创伤量表、情绪调节困难量表和青少年社交焦虑量表对纳入的282名青少年进行评定。采用Pearson相关分析检验各量表评分的相关性，采用Process 4.1中的模型4和58检验情绪失调和社交焦虑在童年创伤与NSSI行为之间的作用路径。结果 童年创伤与NSSI行为之间呈正相关。情绪失调在童年创伤与NSSI行为之间的部分中介作用显著，中介效应占总效应的40.14%。社交焦虑能够调节童年创伤与情绪失调之间的关系；同时，社交焦虑也在情绪失调与NSSI行为之间起调节作用。结论 情绪失调在童年创伤与NSSI行为之间起中介作用，社交焦虑在童年创伤与NSSI行为之间起双重调节作用。

英文摘要:

      Background: Non-suicidal self-injury (NSSI) has emerged as a global public health concern affecting adolescent physical and psychological well-being. The Experiential Avoidance Model posits that childhood trauma contributes to NSSI behavior through the mediating pathway of emotional dysregulation. However, existing research has predominantly focused on isolated psychological or social factors, with limited attention to their interactive effects. Objective: This study aimed to examine the relationship between childhood trauma and NSSI among adolescents, and to analyze the mediating role of emotional dysregulation and the moderating role of social anxiety. Methods: A total of 282 adolescents were assessed using the General Information Questionnaire, Functional Assessment of Self-Mutilation Scale, Childhood Trauma Questionnaire, Difficulties in Emotion Regulation Scale, and Social Anxiety Scale for Adolescents. Pearson correlation analysis was conducted to examine intercorrelations among variables. The mediating role of emotional dysregulation and the moderating role of social anxiety in the association between childhood trauma and NSSI were tested using Model 4 and Model 58 of the PROCESS macro (version 4.1) for SPSS. Results: Childhood trauma was positively associated with NSSI behavior. Emotional dysregulation significantly partially mediated the relationship between childhood trauma and NSSI, accounting for 40.14% of the total effect. Social anxiety moderated the association between childhood trauma and emotional dysregulation, as well as the relationship between emotional dysregulation and NSSI behavior. Conclusions: Emotional dysregulation serves as a mediator in the pathway from childhood trauma to NSSI, while social anxiety exerts a dual moderating role in this relationship.
