Feasibility, Acceptability and Effectiveness of the SOmNI Mobile Phone App for Sleep Promotion in Adolescents

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.
