ABSTRACT

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 ( r=0.281-0.389, P<0.01), while each of them was negatively correlated ( r=-0.453--0.194, all 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. Conclusion:Self-control and rumination have mediating effects between neuroticism and insomnia in college students.
