The relationship between self-control and obsessive-compulsive symptoms:the chain mediating effect of procrastination and anxiety Palizhati·Muhetaer

目的探究大学生自我控制与强迫症状的关系,以及拖延与焦虑在两者间的中介作用。方法采用自我控制量表、拖延问卷、症状自评量表对6367名大学生进行问卷调查。采用SPSS 23.0进行描述性分析、Pearson相关分析,Mplus 7.4进行模型拟合度检验,并用PROCESS宏程序的Bootstrap法进行链式中介效应检验。结果Pearson相关分析显示,自我控制、拖延、焦虑和强迫症状之间存在显著相关(r=-0.71~0.78,均P<0.01)。中介效应分析表明,自我控制对强迫症状的总间接效应(效应值为-0.303)显著,占总效应的63.13%;拖延在自我控制和强迫症状之间的效应值为-0.045,占总效应的9.38%;焦虑在自我控制和强迫症状之间的效应值为-0.239,占总效应的49.79%;此外拖延、焦虑在自我控制和强迫症状之间的链式中介作用显著,效应值为-0.019,占总效应的3.96%。结论自我控制显著负向预测强迫症状,并且拖延和焦虑在自我控制和强迫症状之间起链式中介作用。

Objective To investigate the relationship between self-control and obsessive-compulsive symptoms(OCS),and the mediating role of procrastination and anxiety in this relation.Methods Totally 6367 Chinese college students were recruited to complete the Chinese version of the self-control scale,the Aitken procrastination inventory,and the symptom checklist-90.Descriptive analysis and Pearson correlation were carried out using SPSS 23.0.Mplus 7.4 was used to test the model fit.The mediating effects were tested using the Bootstrap method.Results Pearson correlation analysis showed that there were significant correlations among self-control,procrastination,anxiety,and obsessive-compulsive symptoms(r=-0.71-0.78,P<0.01).Mediation modeling analysis showed that the total indirect effect of self-control on OCS was-0.303,accounting for 63.13%of the total effect.The mediating effect of procrastination between self-control and OCS was-0.045,accounting for 9.38%of the total effect.The mediating effect of anxiety between self-control and OCS was-0.239,accounting for 49.79%of the total effect.Moreover,the chain mediating effect of procrastination and anxiety between self-control and OCS was also significant,with an effect value of-0.019,accounting for 3.96%of the total effect.Conclusion Self-control can negatively predict OCS,procrastination and anxiety play a chain mediating role in the effect of self-control on OCS.
