摘　　要：青少年是自伤行为的高发人群,并且近年来青少年的自伤发生率有日渐上升的趋势。本研究基于边界模型探讨同一性混乱与青少年自伤行为的关系,并从体验回避的视角提出一个有调节的中介模型,考察疏离感的中介作用和情绪调节困难的调节作用。采用自伤行为量表、同一性混乱量表、疏离感量表和情绪调节困难量表对1319名中学生进行测查,结果表明:(1)在控制了性别和年龄后,同一性混乱显著正向预测青少年自伤,疏离感在二者之间起中介作用;(2)疏离感在同一性混乱和青少年自伤之间的中介效应受到情绪调节困难的调节,只有当情绪调节困难水平较高时,疏离感的中介作用才显著。本研究将同一性这一青少年发展的中心任务与自伤联系起来,对青少年自伤的预防和干预具有一定的指导意义。Adolescents are at high risk of non-suicidal self-injury(NSSI),and the prevalence rate of adolescent NSSI has been increasing in recent years.Based on the boundaries model of NSSI,this study aimed to explore the relationship between identity confusion and adolescent NSSI.From the perspective of experiential avoidance,a moderated mediation model was proposed to examine the mediating role of alienation and the moderating role of difficulties in emotional regulation.1319 adolescents were investigated using the Non-suicidal Self-injury Scale,the identity subscale from Erikson Psychosocial Inventory,the interpersonal alienation subscale from Adolescent Students Alienation Scale,and the Difficulties in Emotion Regulation Scale.The results indicated that after controlling gender and age,identity confusion was positively associated with adolescent NSSI,and this association was mediated by alienation.Difficulty in emotion regulation moderated the mediation effect of alienation in the association between identity confusion and NSSI.Specifically,the mediation effect of alienation was significant only for the adolescents with higher level of difficulties in emotion regulation.This study examines the relationship between the central task of adolescent development(i.e.,identity)and NSSI,which has practical implications for preventing and reducing adolescent NSSI.
