Maintaining Behavior Change: A 6-year Follow-up of Adolescent 'Night-owls'

A follow-up of a cohort of participants recruited for a prior study will be conducted. In the prior study, 10-18 years olds were provided one of two treatments to improve the sleep of adolescent night-owls. This follow-up will be conducted approximately 6-years following participation in the prior study. The participants will be 18-28 years of age. Specific Aim 1: At the 6-year follow-up, participants recruited for the prior study will be assessed for sleep and circadian functioning and functioning in five health- relevant domains. Specific Aim 2: The sample will also be assessed for their engagement in sleep health behavior. This research will advance knowledge on: (a) longer-term outcomes and (b) the role of eveningness as a mechanism contributing to poorer outcomes.
