Abstract:
Objective:To investigate the relationship between bedtime procrastination and daytime sleepiness in college students,and to explore the mediating effect of sleep quality and the moderating effect of gender in the a-bove-mentioned relationship.Methods:A total of 2 823 college students(808 males,2 015 females)from two uni-versities were selected.They were assessed with the Bedtime Procrastination Scale(BPS),Epworth Sleeping Scale(ESS,ESS score≥11 indicated daytime sleepiness)and Pittsburgh Sleep Quality Index(PSQI).Process model 4 was used to test the mediating effect of sleep quality and model 14 was used to test the moderating effect of gender.Results:There were 1 214(43.0％)college students suffering from daytime sleepiness.The scores of ESS in college students were positively associated with the BPS scores(β=0.16).The total scores of PSQI partially mediated the effect of BPS scores on college students'ESS scores,and the value of mediating effect was 39.9％.The association between PSQI scores and ESS scores was moderated by gender(β=-0.13).Conclusion:Daytime sleepiness is associated with bedtime procrastination and sleep quality in college students,and the association be-tween sleep quality and daytime sleepiness is moderated by gender.
