Association between Chronotype and Sleep Quality among Chinese College Students: The Role of Bedtime Procrastination and Sleep Hygiene Awareness

Yingying Zhu et al.

Summary: This study examined the relationship between chronotype and sleep quality among Chinese college students, as well as the mediating role of bedtime procrastination and the moderating role of sleep hygiene awareness. The results showed that evening-type students had the lowest sleep quality and highest levels of bedtime procrastination, while morning-type students had the highest sleep quality and lowest levels of bedtime procrastination. Bedtime procrastination partially mediated the relationship between chronotype and sleep quality. Sleep hygiene awareness moderated the direct effect of chronotype on sleep quality and the effect of chronotype on bedtime procrastination. Improving sleep hygiene awareness and reducing bedtime procrastination are important for enhancing sleep quality among college students.
