Condition: Depression, Unipolar · Eveningness · Sponsor: The University of Hong Kong
The goal of this prospective randomised controlled trial is to examine the effects of cognitive behavioural therapy and bright light therapy in youths with unipolar depression and evening chronotype. The main questions it aims to answer are: 1. What is the efficacy of CBT-D and CBT-D plus bright light therapy in reducing depression severity in adolescents with depression and eveningness? 2. What are the effects of CBT-D and CBT-D plus bright light therapy on the subjective and objective sleep and circadian measures, as well as the quality of life, daytime symptoms, and functioning (e.g., sleepiness, fatigue)? Participants will participate in 8 weekly group sessions of CBT-D intervention based on the well-established CBT elements for treating depression. Concurrently participants will also be asked to wear a portable light device at home for 30 minutes daily for seven weeks, starting from the second week of the group intervention. Participants in the CBT-D only group will receive a placebo light via the device, whereas participants in the CBT-D plus light therapy group will receive the active bright light via the device.
