欺凌受害对初中生自伤行为的影响:有调节的中介模型

The Impact of Bullying Victimization on Self-injury Behavior Among Middle School Students:A Moderated Mediation Model

目的:探究初中生欺凌受害与自伤行为的关系及其作用机制。方法:采用特拉华欺凌受害量表、青少年自我伤害问卷、广泛性焦虑量表和社会支持评定量表对1081名初中生进行间隔时间为6个月的两阶段追踪测量。结果:(1)欺凌受害对初中生的自伤行为具有显著的正向预测作用;(2)欺凌受害通过焦虑情绪的中介作用影响初中生的自伤行为;(3)社会支持调节模型的直接路径和后半段路径,具体表现为:随着社会支持水平的提高,欺凌受害对自伤行为的预测作用降低;焦虑情绪对自伤行为的影响随着社会支持水平的增加而减弱。结论:初中生欺凌受害与自伤行为之间存在有调节的中介效应,焦虑情绪是二者关系的中介因素,且该中介效应受到社会支持的调节。

Objective:To explore the relationship between bullying victimization and self-injury behavior among mid-dle school students and its underlying mechanism.Methods:Delaware Bullying Victimization Scale-Student,Adolescent Self-Harm Questionnaire,Generalized Anxiety Disorder-7,and Social Support Rating Scale were used to conduct two-stage tracking measurements with a six-month interval on 1,081 middle school students.Results:(1)Bullying victimiza-tion significantly positively predicted self-injury behavior in middle school students;(2)Bullying victimization influenced self-injury behavior in middle students through the mediation of anxiety;(3)Social support moderated the direct path and the latter half of the path of the model,which was specifically shown as a decrease in bullying victimization's predictive ef-fect on self-injury behavior as the level of social support increased;and anxiety's positive effect on self-injury behavior was attenuated as the level of social support increased.Conclusion:There is a moderated mediating effect between bully-ing victimization and self-injury behavior among middle school students:anxiety is a mediator of the relationship between the two,and the mediating effect is moderated by social support.
