This study aims to evaluate the feasibility, effectiveness, and dissemination potential of an innovative strategy for improving access to effective sleep health care for adolescents. The study will test an adaptation of the Transdiagnostic Sleep and Circadian Intervention (TranS-C), a brief sleep intervention with demonstrated efficacy for improving sleep and mental health outcomes in youth.

This adaptation is designed to address the following key challenges to accessing care: (1) to overcome the challenge of low availability of qualified providers as a barrier to treatment access, we have adapted TranS-C for online and mobile device delivery (referred to as mTranS-C), thereby leveraging the high rates of mobile phone and internet use in adolescents; (2) to further increase access we will disseminate mTranS-C within primary care services, a proven strategy for improving access to behavioral health care; and (3) we focus on low-income communities, where there is a higher prevalence of sleep problems and low access to services.

Inclusion Criteria:

• age 12-18 years
• a sleep health deficit
• youth has access to a mobile phone or internet
• youth is fluent in English.

Exclusion Criteria:

• current use of medications or herbs with known effects on sleep
• current substance use disorder
