The Childhood Trauma and Adolescent Internet Addiction:the Chain Mediation of Depression Symptoms and Academic Burnout and the Moderating Role of Gender
摘要
Abstract
Background The detection rate of internet addiction among Chinese adolescents is high,and its harmful effects are increasingly prominent.Previous studies have indicated strong associations between childhood trauma,depressive symptoms,and academic burnout with internet addiction,while gender factors may also play a moderating role.However,the underlying mechanisms among these variables remain to be further investigated.Objective This study aims to construct a moderated chain mediation model to examine the relationships among childhood trauma,depressive symptoms,academic burnout,gender,and internet addiction,providing a theoretical basis for prevention and intervention.Methods In February 2022,students from all 10 secondary schools in a district of Chengdu were selected as the study subjects.General information was collected through questionnaires,and childhood trauma,depressive symptoms,academic burnout,and internet addiction levels were assessed using the Childhood Trauma Questionnaire Short Form(CTQ-SF),Patient Health Questionnaire Depression Scale(PHQ-9),Adolescent Academic Burnout Scale(AABS),and Internet Addiction Diagnostic Scale for Adolescents(IADDS),respectively.Spearman correlation analysis was used to examine the relationships between the scores of the scales.Moderated chain mediation model analysis was performed using the SPSS macro program Process 3.5,and Bootstrap method was used to test the mediation and moderation effects.Simple slope analysis was applied to compare the interaction effects.Results A total of 34 534 valid questionnaires were collected,with an effective response rate of 84.60%.Among them,5 869 adolescents self-reported childhood trauma experiences and completed the CTQ-SF scale,which were included in the final analysis.Correlation analysis showed that the CTQ-SF score was positively correlated with the PHQ-9 score(rs=0.266,P<0.01),AABS score(rs=0.203,P<0.01),and IADDS score(rs=0.156,P<0.01).The PHQ-9 score was positively correlated with both the AABS score(rs=0.307,P<0.01)and the IADDS score(rs=0.184,P<0.01).The AABS score was positively correlated with the IADDS score(rs=0.278,P<0.01).PHQ-9 scores and AABS scores partially mediated the relationship between CTQ-SF scores and IADDS scores,accounting for 13.51%and 16.22%of the total effect,respectively.The chain mediation effect of both was 10.81%of the total effect.Gender moderated the relationship between CTQ-SF scores and PHQ-9 scores(β=0.020,P<0.01)and IADDS scores(β=-0.013,P<0.01).The simple slope analysis showed that the predictive effect of CTQ-SF scores on male IADDS scores(β=0.029,P<0.001)was significantly higher than on females(β=0.016,P<0.001);whereas the predictive effect of CTQ-SF scores on female PHQ-9 scores(β=0.085,P<0.001)was significantly higher than on males(β=0.064,P<0.001).Conclusion Depression symptoms and academic burnout play a chain mediating role in the relationship between childhood trauma and internet addiction.Childhood trauma predicts internet addiction more strongly in males,while its predictive effect on depression symptoms is stronger in females.关键词
