手机成瘾与大学生学业拖延:有调节的中介模型

Mobile phone addiction and academic procrastination of college students:moderated mediation model

目的基于自我控制双系统模型的视角,探究手机成瘾对学业拖延的影响以及自我控制双系统和认知情绪调节策略在其中的作用机制。方法采用手机成瘾指数量表(mobile phone addiction index scale,MPAI)中文版、学业拖延量表(procrastination assessment scale-students,PASS)、青少年自我控制双系统量表(dual-mode of self-control scale,DMSC-S)以及认知情绪调节问卷中文版(cognitive emotion regulation questionnaire,Chinese version,CERQ-C)对某医学院458名大学生进行问卷调查。结果手机成瘾可正向预测大学生的学业拖延(β=0.434,P<0.001)。冲动系统在手机成瘾和学业拖延之间起部分中介作用(95%CI:0.065~0.178),效应估计值为0.118,中介效应占总效应的27.19%;而控制系统的中介作用不显著。适应性调节策略可以正向调节冲动系统中介作用的后半段路径(INDEX=0.045,95%CI:0.003~0.092);非适应性策略的调节作用不显著。结论手机成瘾可以通过冲动系统对大学生学业拖延产生影响,且该中介作用还会受到适应性调节策略的调节。

Objective To explore the effect of mobile phone addiction on academic procrastination,and investigate the mediating role of self-control dual system and whether cognitive emotion regulation strategies play a moderating role in this mediating process based on a dual system theory.Methods The mobile phone addiction index(MPAI)scale,the procrastination assessment scale-students(PASS),the dual-mode of self-control scale(DMSC-S),and cognitive emotion regulation questionnaire-Chinese version(CERQ-C)were administered to a sample of 458 students from a medical college.Results Mobile phone addiction can significantly predict college students'academic procrastination(β=0.434,P<0.001).The impulse system mediated the relationship between mobile phone addiction and academic procrastination(95%CI:0.065-0.178).The effect estimate was 0.118 and the mediating effect accounted for 27.19%of the total effect.And the mediating effect of the control system did not reach statistical significance.The relationship between impulse system and procrastination was moderated by adaptive cognitive emotion regulation strategies(INDEX=0.045,95%CI:0.003-0.092).And the moderating effect of maladaptive cognitive emotion regulation strategies did not reach statistical significance.Conclusion Mobile phone addiction can affect academic procrastination through the impulse system and the adaptive cognitive emotion regulation strategies can moderate the mediating model.
