Digital Sleep Program for College Students with Insomnia

The participants in the waitlist control group will be informed that they are on a waiting list during the intervention period, serving as a no-treatment control. They will receive the sleep intervention (i.e., the digital-based sleep management program) four weeks after the intervention period is completed.

The digital-based multimodal sleep management program consists of (1) sleep hygiene education, (2) sleep restriction, and (3) mindfulness breathing exercises. The program is internet-integrated and delivered via Google Meet, with 45-minute weekly sessions over four weeks. To increase participants' adherence to the sleep management program , the course instructor will request the participants to record their daily sleep diaries (time to bed, time to sleep, wake time during sleep and wake time) and sleep journals(practices of sleep hygiene, sleep restriction and mindfulness breathing exercise) in the mobile app for at least five consecutive days each week.
