童年期创伤与青少年抑郁的关联及风险机制:多重中介作用与性别差异分析OA

Objective To explore the effects of childhood trauma on adolescent depression and its gender differences,and to analyze the mediating roles of psychological resilience,social support,and internet addiction in these relationships.Methods Using a random sampling method,5,869 middle school students in Chengdu,Sichuan Province,were selected as survey participants and a questionnaire survey was conducted.Structural equation modeling was used to examine the relationships a-mong variables,and multigroup analysis was employed to explore gender differences.Results The structural equation mod-el showed that emotional abuse and physical abuse had positive direct effects on depression(β=0.168,0.083,P<0.05).Emotional neglect had an indirect effect on depression through the chain mediating pathway of psychological resilience to so-cial support(β=0.017,P<0.05).Sexual abuse could amplify the positive effect on depression through internet addiction(β=0.019,P<0.05).Multigroup analysis by gender showed that the effect of emotional neglect on psychological resilience was stronger in females(males:β=-0.233,P<0.05;females:β=-0.273,P<0.05),while the effect of physical neg-lect on psychological resilience was stronger in males(males:β=-0.145,P<0.05;females:β=-0.065,P<0.05).The pathway from emotional abuse through internet addiction was significant in females(β=0.101,P<0.05)but not in males(P>0.05).Conclusion Different dimensions of childhood trauma have different effects on adolescent depression,and gender differences exist.Psychological resilience and social support are protective factors for adolescent depression,while internet addiction is a risk factor.Gender-specific prevention and intervention strategies for adolescent depression should be developed.
