Pursuit of the quantified self in the last decade has transformed the lucrative advancement of consumer sleep trackers (CSTs) for their promise to improve individual sleep behaviours and sleep quality. Among the highest consumers are emerging adults uniquely vulnerable to sleep problems and resulting negative consequences on academic performance and mental health. One driving factor in using CSTs is that few emerging adults can access behavioural sleep medicine treatments. When available (e.g, cognitive behavioural therapy), they do not effectively treat sleep conditions other than insomnia. While Fitbit is a popular CST for sleep problems, recent literature suggests it may not improve individuals' sleep behaviours. One self-management sleep app and a mainstream contender to Fitbit is DOZE (Delivering Online Zzz’s with Empirical Support), rooted in cognitive-behavioural principles to address sleep problems in emerging adults. Given the growing demand for accessible, transdiagnostic behavioural sleep treatments, it is imperative to investigate the efficacy of mainstream self-management interventions in improving individuals' sleep and health behaviours. This study aims to investigate the changes in sleep and health behaviour indices of emerging adults when using Fitbit vs. DOZE. It will provide insight into which consumer self-management sleep interventions are applicable in improving the sleep and well-being of this population and support intervention feasibility and acceptability in our current times of digital tracking.
