What this Trial Is About

Insomnia is prevalent in adolescents. Together with an increase of evening preference (i.e. evening chronotype) in adolescent, sleep disturbance in adolescents are associated with a constellation of adverse outcomes. Insomnia and evening chronotype in adolescents are also found to predict the development of mental health problems and negative health-related outcomes in young adulthood. While cognitive behavioural therapy for insomnia (CBT-I) and bright light therapy were evidenced to be effective in managing sleep problems in adults, there is limited evidence to support their efficacy in children and adolescents. To address the limitations in the existing literature, this study aims to conduct a randomised controlled trial to examine the effects of CBT-I and light therapy on insomnia and mood symptoms, and other clinical and daytime symptoms, as well as overall functioning in adolescents with insomnia (particularly sleep onset insomnia) and evening chronotype.
