Insomnia is the most prevalent sleep problem in children and adolescents and it has been found to predict the development of mental health problems in young adulthood. Cognitive behavioral therapy for insomnia (CBT-I) has been found to be effective in both adults and adolescents. However, limited accessibility and availability of the treatment has only benefited a small proportion of insomnia patients. Therefore, digital CBT-I has been promoted as an alternative way to manage individual's insomnia problems with adequate efficacy. Nonetheless, one of the major limitations of the online self-help intervention is the relatively high drop-out rate and lower compliance compared to the face-to-face modality which the interactive component is less practical in the online intervention. Therefore, the objectives of current study are 1) evaluate the efficacy of mobile-APP based CBT-I in treating youth insomnia, 2) evaluate whether the provision of additional support could further enhance the treatment outcomes.
