Overview
This randomized controlled trial (RCT) study aims to evaluate the effectiveness of a digital-based multimodal sleep management program compared to a waitlist control group in improving sleep-related outcomes, including insomnia severity, daytime sleepiness, objective sleep parameters, and sleep reactivity to stress, as well as psychological health indices, such as depression, anxiety, and resilience. Additionally, this study seeks to examine the mediating role of different chronotypes in the effectiveness of the sleep intervention on the outcomes of interest.
Description
This is a parallel-group, randomized controlled trial (RCT). 90 participants who experiencing insomnia for at least 3 months with college students will be enrolled.
Eligible participants who complete the baseline measurements will be randomly allocated to a digital-based multimodal sleep management program group (N = 45) and a waitlist control group (N = 45).
The primary outcome is insomnia severity, assessed using the Insomnia Severity Index (ISI). The secondary outcomes include daytime sleepiness, objective sleep parameters, sleep reactivity, resilience, anxiety, and depression, which will be examined using the Epworth Sleepiness Scale (ESS), a wearable sleep tracker, the Ford Insomnia Response to Stress Test (FIRST), the Brief Resilience Scale (BRS), the State-Trait Anxiety Inventory (STAI), and the Beck Depression Index II (BDI-II), respectively. Additionally, chronotype will be assessed using the Morningness-Eveningness Questionnaire (MEQ) as a moderating role to be tested in this study. All outcomes will be measured at three time points: T0 (baseline assessment), T1 (immediately after the 4-week intervention period), and T2 (4 weeks after the intervention period).
