Effect of a Smartphone-based, Mood-enhanced Cognitive Behavioral Therapy for Insomnia in Adolescents At Risk of Depression: A Cluster Randomized Trial
Emerging encouraging evidence showed that sleep focused treatment can simultaneously improve sleep and depression in adult with comorbid conditions. Although these favorable changes in depressed adults is encouraging, little is known in the potential efficacy of CBT-I in altering depression trajectory in adolescent population. This current study aims to compare the effect of digitally delivered, mood enhanced cognitive behavioral therapy for insomnia (M-dCBT-I) and standard digital cognitive behavioral therapy for insomnia (dCBT-I) in improving depressive symptoms in adolescents, and to examine the potential sustained treatment effect in mood outcomes following M-dCBT-I or dCBT-I treatment.
