目的:探讨大学生自我控制、反刍思维在神经质与失眠之间的中介作用。方法:采用横断面调查方法，使用中国大五人格问卷极简版、失眠严重程度指数、反刍思维量表及自我控制量表，对四川省某高校的767名大学生进行问卷调查。结果:大学生失眠检出率36.6%；神经质[(9.63±3.41)分]、反刍思维[(22.27±5.44)分]、失眠严重程度指数[(6.61±4.28)分]呈两两正相关(n r＝0.281～0.389，n P<0.01)，与自我控制总分[(60.71±9.41)分]呈负相关(n r＝-0.453～-0.194，n P<0.01)。中介效应分析显示神经质可直接影响失眠，也可分别通过反刍思维和自我控制的中介作用间接影响失眠。n 结论:大学生自我控制、反刍思维在神经质与失眠之间存在中介作用。“,”Objective:To explore the mediating effects of self-control and rumination between neuroticism and insomnia in college students.Methods:A cross-sectional survey was conducted among 767 college students from a university in Sichuan province with Chinese big five personality inventory-15, insomnia severity index, ruminative responses scale, and self-control scale.Results:The prevalence of insomnia was 36.6% among college students.The scores of neuroticism (9.63±3.41), rumination (22.27±5.44) and ISI (6.61±4.28) were positively correlated with each other (n r=0.281-0.389, n P<0.01), while each of them was negatively correlated (n r=-0.453--0.194, all n P<0.01) with self-control (60.71±9.41). Analysis of mediating effects revealed that neuroticism not only directly affected insomnia, but also indirectly affected insomnia through the mediating effects of rumination and self-control respectively.n Conclusion:Self-control and rumination have mediating effects between neuroticism and insomnia in college students.
