无法忍受不确定性与大学生网络成瘾:负性认知偏向和情绪调节困难的多重中介作用

Intolerance of uncertainty and internet addiction among college students:the mediating roles of negative cognitive bias and difficulties in emotion regulation

目的探讨大学生无法忍受不确定性与网络成瘾的关系及负性认知偏向和情绪调节困难在二者关系中的作用。方法2022年9月,使用无法忍受不确定性量表、负性认知加工偏向问卷、情绪调节困难量表和网络成瘾量表对1762名大学生进行横断面调查。采用SPSS 24.0进行描述性统计和相关分析,使用AMOS 23.0构建多重中介模型并采用Bootstrap法进行中介效应检验。结果(1)无法忍受不确定性评分为34.00(28.00,40.00)分,负性认知偏向评分为42.00(34.00,50.00)分,情绪调节困难评分为26.00(20.00,32.00)分,网络成瘾评分为36.00(28.00,46.00)分。(2)Spearman相关分析结果显示,无法忍受不确定性、负性认知偏向、情绪调节困难以及网络成瘾彼此间均呈正相关(r=0.343~0.626,均P<0.01)。(3)路径分析结果显示,无法忍受不确定性对网络成瘾的直接效应不显著,总间接效应为0.402(95%CI=0.354~0.451)。负性认知偏向在无法忍受不确定性和网络成瘾中的间接效应值为0.253(95%CI=0.200~0.305),占总间接效应62.94%(0.253/0.402);情绪调节困难在无法忍受不确定性和网络成瘾中的间接效应值为0.052(95%CI=0.033~0.076),占总间接效应12.93%(0.052/0.402);负性认知偏向和情绪调节困难在无法忍受不确定性和网络成瘾中的链式中介效应值为0.097(95%CI=0.068~0.131),占总间接效应24.13%(0.097/0.402)。结论无法忍受不确定性与网络成瘾显著正相关,且其对网络成瘾的影响分别受到负性认知偏向、情绪调节困难的单独中介作用以及二者的链式中介作用。

Objective To explore the relationship between intolerance of uncertainty and internet addiction among college students,as well as the mediating roles of negative cognitive bias and difficulties in emotion regulation.Methods In September 2022,1762 college students were assessed with intolerance uncertainty scale,negative cognitive process bias questionnaire,difficulties in emotion regulation scale and internet addiction test.SPSS 24.0 software was used for descriptive statistics and correlation analysis.AMOS 23.0 was used to construct a multiple mediation model,and Bootstrap method was used for mediation effects testing.Results(1)The score of intolerance of uncertainty was 34.00(28.00,40.00),the score of negative cognitive bias was 42.00(34.00,50.00),the score of difficulties in emotion regulation was 26.00(20.00,32.00),and the score of internet addiction was 36.00(28.00,46.00).(2)The Spearman correlation analysis showed that intolerance of uncertainty,negative cognitive bias,difficulties in emotion regulation,and internet addiction were significantly positively correlated with each other(r=0.343-0.626,P<0.01).(3)The results of the path analysis indicated that the direct effect of intolerance of uncentainty on internet addiction was not significant,and the total indirect effect was 0.402(95%CI=0.354-0.451).The indirect effect of negative cognitive bias was 0.253(95%CI=0.200-0.305),accounted for 62.94%(0.253/0.402)of the total indirect effect.The indirect effect of difficulties in emotion regulation was 0.052(95%CI=0.033-0.076),accounted for 12.93%(0.052/0.402)of the total indirect effect.And the chain mediating effect of negative cognitive bias and difficulties in emotion regulation was 0.097(95%CI=0.068-0.131),accounted for 24.13%(0.097/0.402)of the total indirect effect.Conclusion Intolerance of uncertainty is significantly positively correlated with internet addiction,and its effects on internet addiction are individually mediated by negative cognitive bias and difficulties in emotion regulation,as well as their chain mediating effects.
