Non-suicidal self-injury (NSSI) is a serious public health concern. Emotional insecurity is a crucial predictor of NSSI among adolescents. However, few studies have elucidated the specific mechanisms between emotional insecurity and NSSI.
This study employed a longitudinal research design, using a sample of 886 Chinese early adolescents (M at T1 = 10.62 years, SD = 0.77 years; 47.40% females), and conducted two surveys six months apart to examine the mediating role of peer exclusion between emotional insecurity and NSSI, as well as the moderating effect of school climate.
The results indicated that peer exclusion significantly mediated the connection between emotional insecurity and adolescent NSSI. Moreover, school climate significantly moderated the connection between emotional insecurity and peer exclusion. Specifically, the impact of emotional insecurity on peer exclusion was significant only in adolescents who reported a negative school climate, but non-significant in those who reported a positive school climate.
These findings provide a robust theoretical foundation and practical insights to help inform the prevention of and interventions for NSSI in adolescents.
非自杀性自伤（NSSI）是一个严重的公共卫生问题。情绪不安全感是青少年非自杀性自伤的关键预测因素。然而，很少有研究阐明情绪不安全感与非自杀性自伤之间的具体机制。
本研究采用纵向研究设计，以886名中国青少年早期学生为样本（T1时的平均年龄M = 10.62岁，标准差SD = 0.77岁；女性占47.40%），相隔六个月进行两次调查，以检验同伴排斥在情绪不安全感与非自杀性自伤之间的中介作用，以及学校氛围的调节作用。
结果表明，同伴排斥在情绪不安全感与青少年非自杀性自伤之间的联系中起显著中介作用。此外，学校氛围显著调节了情绪不安全感与同伴排斥之间的联系。具体而言，情绪不安全感对同伴排斥的影响仅在报告学校氛围消极的青少年中显著，而在报告学校氛围积极的青少年中不显著。
这些发现为帮助预防和干预青少年非自杀性自伤提供了坚实的理论基础和实践见解。
