摘　　要：青春期是同一性发展的关键期,这一时期同时伴随着心理社会发展的不适应问题(例如,自伤)。本研究采用随机截距交叉滞后模型(RI-CLPM),考察青少年同一性混乱和自伤(NSSI)的动态双向作用模式,并检验疏离感在二者之间的中介作用。采用同一性混乱量表、疏离感量表和自伤行为量表对1258名中学生进行为期一年的三波段调查(分别记作T1、T2和T3)。RI-CLPM结果表明:(1)分离了个体间效应后,个体内水平上T1的NSSI显著正向预测T2的同一性混乱,而T2的同一性混乱显著正向预测T3的NSSI,T2的NSSI也显著正向预测T3的同一性混乱。青少年同一性混乱和NSSI之间存在双向影响关系;(2)个体内水平上T2的疏离感在T1的NSSI与T3的同一性混乱的关系中具有纵向中介作用。本研究基于Erikson的心理社会发展理论的视角,将同一性这一青少年的关键发展任务和NSSI在时间尺度上联系起来,对青少年NSSI的预防和干预具有一定的启示意义。Nonsuicidal self-injury(NSSI)is defined as the deliberate,direct,and socially unacceptable destruction of one’s own body tissue without a conscious suicidal intent.This behavior has become a major public health problem among adolescents.The initial occurrence of NSSI and its subsequent peak periods often coincide with the identity crisis stage of adolescents.Identity confusion represents a sense of feeling“mixed up,”that is,being unable to enact and maintain lasting commitments to life alternatives and lacking a clear sense of purpose and direction.Considerable evidence has linked identity confusion to NSSI.According to the identity-NSSI interplay model,NSSI may serve as a means of developing a sense of identity(i.e.,“I am a self-injurer”),which goes against the common values and attitudes in society.The destabilization of a self-injurer may lead individuals to a further increased sense of identity diffusion.Based on this theory,the present study tested the bidirectional association between identity confusion and adolescents’NSSI as well as the mediating role of alienation and the moderating role of gender in this association.A sample of 1258 Chinese middle school students(50.1%girls;Mage at Wave 1=13.81 years)completed self-report questionnaires regarding identity confusion,alienation,and NSSI at three time points(called T1,T2,and T3),with 6-month intervals.The random intercept cross-lagged panel model(RI-CLPM)was employed to separate between-and within-person effects,and to test the mediation role of alienation in the reciprocal relations between identity confusion and adolescent NSSI.Moreover,the multi-group RI-CLPM was used to test the gender differences in the associations among identity confusion,alienation,and NSSI.Results showed that identity confusion and NSSI were mutually reinforcing at the within-person level when controlling for between-person effects.Specifically,initial NSSI significantly and positively predicted T2 identity confusion,which in turn significantly positively predicted T3
