青少年抑郁网络成瘾及遭受校园欺凌网络建模分析

Network modeling analysis of depression,Internet addiction and campus bullying in adolescents

目的 探究青少年抑郁情绪、网络成瘾及校园欺凌及其影响因素间的网络关系,为青少年心理状况及相关危险行为的综合防控提供理论依据。方法 于2020年9月采用分层随机整群抽样方法,在江苏省13个市抽取1个城区、1个郊县,共抽5 000名在校中学生进行调查,采用结构方程模型对抑郁、网络成瘾、校园欺凌及其相关影响因素进行分析。结果 青少年抑郁与网络成瘾呈正向相关(β=0.35,P<0.01);青少年遭受校园欺凌与抑郁状态和网络成瘾呈正向相关(β值分别为0.23,0.05,P值均<0.01)。青少年抑郁在睡眠时长对网络成瘾的影响中发挥部分中介作用,间接效应为-0.01,占总效应的63.6%。青少年抑郁在中高强度运动频次对网络成瘾的影响中发挥部分中介作用,间接效应为-0.01,占总效应的21.8%。结论 青少年抑郁、网络成瘾、遭受校园欺凌间相互影响,在制定预防和干预策略时需全面考虑其影响因素,从而有针对性地提出综合预防和干预策略,为促进学生身心健康提供科学有效的保障。

Objective To explore network relationships among depression,Internet addiction and campus bullying among adolescents,so as to provide a theoretical basis for the comprehensive prevention and control of adolescents'psychological status and risky behaviors.Methods In September 2020,a stratified random cluster sampling method was adopted to select 5000 middle-school students for investigation.A structural equation model was used to analyze depression,Internet addiction and bullying and their related influencing factors in order to clarify the pathway and magnitude of effects.Results Depression had a positive effect on Internet addiction with adolescents(β=0.35,P<0.01),school bullying had a positive effect on depression and Internet addiction with adolescents(β=0.23,0.05,P<0.01).Adolescent depression was found to play a partial mediating role with respect to the influence of sleep duration on Internet addiction,and the indirect effect was-0.01,accounting for 63.6% of the total effect.Depression played a partial mediating role regarding the influence of the frequency of moderate and high intensity exercise on Internet addiction in adolescents;the indirect effect was-0.01,accounting for 21.8% of the total effect.Conclusion Considering the interaction among adolescent depression,Internet addiction,and school bullying,it's important to include associated factors when developing effective prevention and intervention strategies,which can thus promote the physical and mental health of students,and provide scientific and effective protection.
