简要总结
The hiSG Sleep Health Study seeks to investigate the efficacy of education + goal-based programmes for the promotion of healthy sleep habits and to evaluate its impact on daytime sleepiness and mental health.
详细描述
This study is a sub-study under the existing Health Insights Singapore study (hiSG). The hiSG study is a longitudinal cohort study among working adults (aged 21-42y), monitoring health parameters through a Fitbit tracker and mobile phone-based questionnaires.
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.

结局指标
主要结局
Change in bedtimes measured by wearable device
时间窗: Baseline (Week 1-2), Intervention (Week 11-12), Follow up (Week 21-22)
We hypothesize that the Goal-Setting group will exhibit earlier bedtimes across both Intervention and Follow-Up phases, compared to the Tracking group.
Change in bedtime regularity (standard deviation) measured by wearable device
时间窗: Baseline (Week 1-2), Intervention (Week 11-12), Follow up (Week 21-22)
We hypothesize that the Goal-Setting group will exhibit more consistent bedtimes across both Intervention and Follow-Up phases, compared to the Tracking group.
Change in social jetlag (midpoint of sleep on weekends - weekdays) measured by wearable device
时间窗: Baseline (Week 1-2), Intervention (Week 11-12), Follow up (Week 21-22)
We hypothesize that the Goal-Setting group will exhibit reduced social jetlag measures across both Intervention and Follow-Up phases, compared to the Tracking group.
Change in scores on the Work-Related Perseverative Thought and Work Home Interference questionnaires
时间窗: Baseline (Week 1-2), Intervention (Week 11-12), Follow up (Week 21-22)
We hypothesize that the Goal-Setting group will exhibit reduced work stress levels across both Intervention and Follow-Up phases, compared to the Tracking group.
Change in sleep duration measured by wearable device (mins)
时间窗: Baseline (Week 1-2), Intervention (Week 11-12), Follow up (Week 21-22)
We hypothesize that the Goal-Setting group will exhibit longer sleep duration across both Intervention and Follow-Up phases, compared to the Tracking group.
Change in scores on the Sleep Health Index questionnaire
时间窗: Baseline (Week 1-2), Intervention (Week 11-12), Follow up (Week 21-22)
We hypothesize that the Goal-Setting group will exhibit improved sleep health across both Intervention and Follow-Up phases, compared to the Tracking group.
Change in scores on the Sleep Hygiene Scale questionnaire
时间窗: Baseline (Week 1-2), Intervention (Week 11-12), Follow up (Week 21-22)
We hypothesize that the Goal-Setting group will exhibit better sleep hygiene across both Intervention and Follow-Up phases, compared to the Tracking group.
Change in sleep duration regularity (standard deviation) measured by wearable device (mins)
时间窗: Baseline (Week 1-2), Intervention (Week 11-12), Follow up (Week 21-22)
We hypothesize that the Goal-Setting group will exhibit more consistent sleep durations across both Intervention and Follow-Up phases, compared to the Tracking group.
Change in scores on the Oldenberg Burnout Inventory questionnaire
时间窗: Baseline (Week 1-2), Intervention (Week 11-12), Follow up (Week 21-22)
We hypothesize that the Goal-Setting group will exhibit reduced burnout across both Intervention and Follow-Up phases, compared to the Tracking group.
