焦虑和认知情绪调节在青少年网络成瘾与抑郁之间的中介作用

Mediating effects of anxiety and cognitive emotion regulation on Internet addiction and depression in adolescents

目的探讨青少年网络成瘾与抑郁的关系以及焦虑与认知情绪调节的中介作用。方法采用网络成瘾测评量表、广泛性焦虑量表、Kutcher青少年抑郁量表和认知情绪调节问卷于2015年12月至2016年1月对上海市5所普通公立初级中学选取的2751名学生进行现场问卷调查。结果初中生抑郁症状的检出率为22.2%(610/2751),在高年级、家庭情况较差的学生中的抑郁症状更常见(P<0.05)。相关分析结果显示,网络成瘾、抑郁、焦虑和非适应性认知情绪调节策略两两均呈正相关,相关系数为0.354~0.755(均P<0.01)。结构方程模型分析结果显示,焦虑和非适应性认知情绪调节策略在青少年网络成瘾和抑郁间起中介作用,非标准化的间接效应值分别为0.340和0.031,两者的中介效应量分别占总间接效应的91.64%和8.36%,且该作用为并行式中介作用;多个拟合度指标显示,中介效应模型拟合较好(χ;/DF=1.035,GFI=0.975,AGFI=0.939,RMSEA=0.004,TLI=0.999,CFI=0.999,NFI=0.975,IFI=0.999,RFI=0.967)。结论青少年网络成瘾对抑郁有一定预测作用,也可以通过焦虑和非适应性认知情绪调节策略发挥间接作用。

Objective To explore the association between Internet addiction and depression among adolescents,as well as the mediating effects of anxiety and cognitive emotion regulation.Methods An on-site questionnaire survey was conducted among 2751 students selected from five public junior middle schools in Shanghai from December 2015 to January 2016 by using the Internet Addiction Assessment Scale,Generalized Anxiety Disorder-7,Kutcher Adolescent Depression Scale and Cognitive Emotion Regulation Questionnaire.Results The detection rate of depression was 22.2%(610/2751),and depression symptoms were more common among students in higher grades and poorer families(P<0.05).The results of correlation analysis showed that Internet addiction,depression,anxiety,and non-adaptive cognitive emotion regulation strategies were significantly positively correlated,with correlation coefficients ranging from 0.354-0.755(all P<0.01).The structural equation model(SEM)indicated that anxiety and maladaptive strategies played parallel mediating roles between Internet addiction and depression.The non-standardized indirect effect values of anxiety and nonadaptive strategies are 0.340 and 0.031,respectively,and the mediating effect of the two accounts for 91.64%and 8.36%of the total indirect effect.Various fit measures indicate that the mediation effect model fits well.(χ;/DF=1.035,GFI=0.975,AGFI=0.939,RMSEA=0.004,TLI=0.999,CFI=0.999,NFI=0.975,IFI=0.999,RFI=0.967).Conclusions Adolescent Internet addiction can predict depression,and it can also play an indirect role through anxiety and non adaptive cognitive emotion regulation strategies.
