Abstract:

Based on the Research Domain Criteria (RDoC) framework, this study investigated the relationship between core self-evaluations and non-suicidal self-injury (NSSI) in adolescents, with a focus on the mediating role of insomnia severity and the moderating role of parental autonomy support. A total of 4,760 middle and high school students were recruited and completed a battery of well-validated scales, including the Adolescent Self-Harm Scale, Core Self-Evaluations Scale, Insomnia Severity Index, and Parental Autonomy Support Scale. The results demonstrated that: 1) core self-evaluations negatively predicted NSSI; 2) insomnia severity mediated the relationship between core self-evaluations and NSSI; and 3) parental autonomy support moderated the direct path, the second stage of the mediation pathway, and the overall indirect effect. These findings provide evidence-based guidance for developing tailored intervention strategies to address self-injury among adolescents.

Key words: adolescent self-injury, core self-evaluation, insomnia severity, parental autonomy support

摘要:

基于研究领域标准框架探讨核心自我评价与青少年自伤行为的关系,以及失眠程度的中介作用和父母自主支持的调节作用。以4760名初高中生为被试,采用青少年自我伤害问卷、失眠严重程度指数量表、核心自我评价量表和父母自主支持量表开展问卷调查研究。结果发现,核心自我评价负向预测青少年自伤行为;失眠程度在核心自我评价和青少年自伤行为之间起中介作用;该中介模型的直接路径与后半路径,以及其间接效应受父母自主支持水平的调节。本研究为构建青少年自伤行为的差异化干预方案提供循证依据。
