Abstract:

The present study constructed a moderated mediation model to explore the relationship between bedtime procrastination and daytime sleepiness in college students, and further to examine the mediating effect of insomnia and the moderating effect of chronotype by using the Bedtime Procrastination Scale, Insomnia Severity Index Scale, Epworth Sleepiness Scale and Morningness-Eveningness Questionnaire. A total of 4252 college students were recruited to participate in this study. The results showed that: 1) bedtime procrastination had a significant positive prediction on daytime sleepiness; 2) insomnia played a partial mediating role in the relationship between bedtime procrastination and daytime sleepiness; 3) the association between bedtime procrastination and insomnia was moderated by chronotype. Compared to the students with morningness, the prediction effect of bedtime procrastination on insomnia was much stronger in individuals with eveningness.

Key words: bedtime procrastination, daytime sleepiness, insomnia, chronotype, college students

摘要:

本研究探讨了大学生睡眠拖延与日间嗜睡的关系,以及失眠在其中的中介作用和睡眠时型在其中的调节作用。采用睡眠拖延量表、失眠严重程度指数量表、Epworth嗜睡量表和睡眠时型量表对4252名大学生进行调查。结果表明:(1)睡眠拖延对日间嗜睡有显著的正向预测作用;(2)失眠在大学生睡眠拖延与日间嗜睡的关系中起部分中介作用;(3)睡眠拖延经由失眠影响日间嗜睡的中介作用受到睡眠时型的调节,相对于清晨型,睡眠拖延对夜晚型大学生失眠的预测作用更强。
