Overview
Brief Summary
This study will recruit 60 night shift workers with shift work disorder. They will be invited to wear actigraphy for 3 weeks. In the first week the participants will sleep at the time they used to, and their chronotype will be determined by actigraphy and Munich Chronotype Questionnaire. In the second week the participants will be randomly assigned to morning sleep or evening sleep time, and will change to the other in the third week. We will compare sleepiness, sleep quality, daytime vigilance score changes using mixed method ANOVA. We will also examine the interaction effect of chronotype and sleep schedule on sleep-related outcome.
