About

Major depressive disorder (MDD) is among the most common psychiatric disorders among adolescents, and is associated with considerable psychosocial and functional impairments and an elevated risk of suicidal behaviour and completed suicide. Meanwhile, sleep disturbance, particularly insomnia, is among the most prevalent and prominent presenting complaints in adolescents with depression. Despite its high prevalence, insomnia often remains overlooked and under-treated in clinical practice. However, growing evidence suggests an intricate relationship between insomnia and depression, which has become an area in need of further focused attention. This project will involve a randomised controlled trial proposed to examine whether insomnia treatment confers additional benefit to depression treatment in adolescents with comorbid depression and insomnia, for improving sleep and depressive symptoms, and other clinical and daytime symptoms as well as overall functional improvement in both the short and long term. Eligible adolescent participants will be randomised to either intervention (8-week group Cognitive Behavioural Therapy for Insomnia, CBT-I, or 8-week group Cognitive Behavioural Therapy for Depression, CBT-D) or waiting-list control condition. Assessments will be conducted at pre-treatment (week 0), during the treatment (week 2, 4, 6) and post-treatment (week 8/at the conclusion of the last group session). The two active treatment groups will be additionally followed up at posttreatment one-month and six-month.
