目的:探讨网络成瘾对青少年非自杀性自伤(NSSI)的影响,检验精神病性体验在两者间的中介作用以及双元自主性的调节效应.方法:采用网络成瘾问卷、非自杀性自伤问卷、双元自主性问卷和简式版社区心理评估量表对6053名13~22岁的青少年施测.结果:①网络成瘾显著正向预测青少年NSSI(r=0.37,P<0.001);②精神病性体验在网络成瘾与NSSI间起部分中介作用(β=0.61,t=35.60,P<0.001);③双元自主性在中介路径的后半段"精神病性体验→NSSI"中起调节作用(β=-0.01,t=-11.17,P<0.05).结论:网络成瘾不仅可以直接预测非自杀性自伤,还会通过精神病性体验对其产生间接影响,同时双元自主性对此中介路径(后半段)起调节作用.
Objective:To explore the impact of internet addiction on non-suicidal self-injury(NSSI)in adoles-cents,and to examine the mediating role of psychotic-like experiences as well as the moderating effect of dual au-tonomy.Methods:A total of 6,053 adolescents aged 13~22 were surveyed using the Internet Addiction Question-naire,Non-Suicidal Self-Injury Questionnaire,Dual Autonomy Questionnaire,and the Brief Community Psycho-logical Assessment Scale.Results:①Internet addiction significantly positively predicted adolescent NSSI(r=0.37,P<0.001);②Psychotic-like experiences partially mediated the relationship between internet addiction and NSSI(β=0.61,t=35.60,P<0.001);③Dual autonomy moderated the latter half of the mediation pathway"psychotic-like experiences NSSI"(β=-0.01,t=-11.17,P<0.05).Conclusion:Internet addiction not only directly predicts non-suicidal self-injury but also indirectly influences it through psychotic-like experiences,while dual autonomy mod-erates this mediation pathway(latter half).
