Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The hiSG Sleep Health Study (hiSG SHS) sub-study, will evaluate the efficacy of two goal-based interventions for improving sleep. Participants will be recruited from the existing hiSG subject pool (target N=300), and should have a habitual sleep duration below the recommended 7h (as determined from the currently available hiSG data). Following informed consent, participants will be randomized by the study team into two groups, a) Goal-Setting and b) Tracking, based on a 2:1 ratio, i.e. in the event 300 participants are enrolled, 200 will be allocated to Goal-Setting and 100 to Tracking.
The study is 22 weeks long and will proceed in 3 main phases, namely, 1) Baseline (Week 1-2) 2) Intervention (Week 3-12), and 3) Follow-up (Week 13-22).
Throughout the study, participants in both groups will be rewarded for logging their nightly sleep sessions regularly on their study wearable device, based on a weekly completion bonus for a minimum of 3 nights of sleep preceding weekdays (Sunday - Thursday nights) per week.
Daily questionnaires probing daytime sleepiness, mood, and stress levels as well as once-per-study phase sleep health, sleep hygiene, work-related stress and mental wellbeing questionnaires will be pushed to participants during the baseline (Week 1-2), intervention (Week 11-12) and follow-up periods (Week 21-22) via the hiSG mobile application. Participants will also be reimbursed for completion of these questionnaires.
Both groups will also receive sleep education tips before the intervention period. During the intervention phase, the Goal-Setting group will be additionally rewarded for achieving sleep goals, i.e. 30 mins longer than their habitual sleep duration and sleeping before midnight.
In addition, given the pervasive telecommuting arrangements presently enforced in many workplaces to curb spread of the COVID-19 pandemic, a work-life balance, burnout and work engagement questionnaire will be administered to better understand reasons that could contribute to poor sleep health and mental wellbeing.
