BackgroundThe persistently high prevalence of insomnia seriously affects the quality of life of all populations. Studies showed that state-trait anxiety， resilience and neuroticism are related to the occurrence of insomnia， while the research on the relationship among the four factors in college students is still insufficient.ObjectiveTo discuss the impact of neuroticism on insomnia among college students， and to examine the mediating role of state-trait anxiety and resilience in the relationship between neuroticism and insomnia， thus providing references for the intervention of insomnia in college students.MethodsFrom September to December 2020， simple random sampling techniques were utilized to select 1 416 students in a university in Sichuan province， and all subjects were assessed using State-Trait Anxiety Inventory （STAI）， Connor-Davidson Resilience Scale （CD-RISC）， Chinese Big Five Personality Inventory-15 （CBF-PI-15） and Insomnia Severity Index （ISI）. Then Pearson correlation analysis was conducted to examine the correlation among the above four scales， and the mediating role of STAI and CD-RISC in the relationship between CBF-PI-15 neuroticism dimension and ISI was verified by Process macro mediation analysis.ResultsInsomnia was reported in 241/1 416 （17.02%） college students. The prevalence rate of insomnia in male students was higher than that in female students， with statistical difference （χ2=16.417， P<0.01）. Total ISI score was positively correlated with CBF-PI-15 neuroticism dimension and total STAI score （r=0.127， 0.563， P<0.01）， and negatively correlated with total CD-RISC score （r=-0.149， P<0.01）. State-trait anxiety and resilience of college students had a chain mediation effect on the relationship between neuroticism and insomnia （indirect effect size was -0.011）， and the size of direct effect of neuroticism on insomnia was 0.120， accounting for 75.00% of the total effect.ConclusionState-trait anxiety and resilience of college students exert a chain mediation effect on the relationship between neuroticism and insomnia， so the neuroticism causes an impact on insomnia both directly and indirectly through the chain mediating effect of state-trait anxiety and resilience.
