This study evaluates the acceptability, feasibility, and efficacy of an intervention using wearable sensors and a mHealth application, SOmNI, to promote sleep for adolescents. The investigators hypothesize that a behavioural intervention delivered through a mobile app will be a cost-effective and accessible method of engaging adolescents in the self-management of sleep behaviours. Participants will be randomized to either the SOmNI Intervention group or the Control group. Participants receiving the SOmNI app will attempt to incrementally move their school night bedtime earlier in the evening.
Over 60% of adolescents sleep less than the 9 hours of sleep recommended for 13-18 year olds. Quality of life is reduced due to the daytime consequences of chronic sleep deprivation such as sleepiness, fatigue, low mood, and inattentiveness at school. Although this sleep debt occurs in otherwise healthy adolescents, it significantly increases their risk of development of the chronic health conditions (cardiovascular disease and depression) and forms of accidental injury (motor vehicle accidents) that place the greatest demands on our health care system. Despite increased recognition of adequate sleep as a key contributor to health, there exist few effective interventions to promote sleep in adolescents. This study is designed to determine compliance, feasibility and preliminary data on health outcomes (nocturnal sleep measured objectively by actigraphy; daytime sleepiness; anxiety; depression; unintentional injuries; morning school attendance). This study will be a pilot RCT, randomizing 76 adolescents to one of two groups (i.e. 38 per group). Study arms will include a control group and intervention group (activity monitoring device with custom application). Mobile health, user-friendly low-intensity interventions with wearable sleep sensors and tailored feedback may help many adolescents to increase the amount of sleep they achieve.

In addition to allowing users to track sleep behaviours across the four-week intervention period, the SOmNI app will also provide messaging via alerts and tips to outline the importance of sleep to health, suggest optimal sleep timing/duration, and suggest sleep promotion strategies. Daily review questions in the app will help the participants link changes in sleep behaviours to changes in health outcomes. As well, when goals related to sleep extension are met, the SOmNI rewards program awards points to the participant and these points can then be redeemed in $5 increments to a maximum of $40 for gift certificates.
The research assistant will advise the participant to increase the amount of nighttime sleep achieved but will not give any sleep hygiene advice or instructions for moving their bedtime earlier.
