Abstract

Previous research has shown that an increase in identity confusion is associated with a higher risk of non-suicidal self-injury (NSSI) in adolescents. Based on the identity-NSSI interplay model, we tested psychological distress as a mediator of this association. Based on the life history theory, we tested whether a slow life history strategy could weaken this mediation process. Five hundred and eighty-two Chinese middle school students (M_age = 13.75, SD = 0.67) completed questionnaires regarding identity confusion, psychological distress, life history strategy, and NSSI in May 2024. The results of structural equation modeling showed that identity confusion significantly predicted adolescent NSSI, and psychological distress mediated the association. Life history strategy moderated the second stage of the indirect effect (i.e., the relationship between psychological distress and NSSI). Specifically, the slower the life history strategy, the weaker the indirect effect of identity confusion on NSSI through psychological distress. These findings highlight the value of integrating life history strategy into research on adolescent NSSI.

身份困惑与青少年非自杀性自伤的关系：心理困扰的中介作用和生活史策略的调节作用

先前的研究表明，身份混淆的增加与青少年非自杀性自伤（NSSI）的高风险有关。基于身份-自伤相互作用模型，我们测试了心理困扰作为这种关联的中介。基于生活史理论，我们测试了慢生活史策略是否会削弱这一中介过程。582名中国中学生（Mage = 13.75, SD = 0.67）于2024年5月完成了身份困惑、心理困扰、生活历史策略和自伤问卷。结构方程模型结果显示，身份混淆对青少年自伤行为有显著的预测作用，而心理困扰在其中起中介作用。生活史策略调节第二阶段的间接效应（即心理困扰与自伤的关系）。具体而言，生活史策略越慢，身份混淆通过心理困扰对自伤行为的间接影响越弱。这些发现突出了将生活史策略整合到青少年自伤研究中的价值。

With its dual focus on victims and victimizers, the journal will publish material that addresses the causes, effects, treatment, and prevention of all types of violence. JIV only publishes reports on individual studies in which the scientific method is applied to the study of some aspect of interpersonal violence. Research may use qualitative or quantitative methods.
