Summary

The proposed study will include a longitudinal ecological study (Study 1) and a randomised controlled trial (Study 2). The aims will be to (1) identify the sleep-wake profiles in individuals with MDD through clustering; (2) examine the associations between sleep-wake features/profiles and the prognosis of MDD; and (3) investigate the anti-depressant effects of sleep- and circadian-targeted intervention in those with MDD and whether sleep-wake features/profiles may moderate the treatment outcomes. 70 depressed participants from Study 1 will be randomized to Study 2 for the Transdiagnostic Intervention for Sleep and Circadian Dysfunction (TranS-C) group and the care-as-usual (CAU) group in a 1:1 allocation ratio. The study period will be 8 weeks. Major assessments at baseline and immediate post-treatment will be managed by an independent assessor (a research assistant, RA) who is blind to the group allocation. The proposed trial and the nested pilot study will follow the CONSORT and STROBE guidelines, respectively. The intervention will be provided free of charge.The current registration is only for Study 2 of the current research project.

BEHAVIORAL

Transdiagnostic Intervention for Sleep and Circadian Dysfunction

This intervention is a non-pharmacological approach that targets various factors contributing to sleep and circadian problems. It incorporates evidence-based elements such as CBT for insomnia, IPSRT, chronotherapy, and motivation enhancement. The treatment consists of 8 sessions with 4 cross-cutting modules: case formulation, sleep and circadian education, motivational interviewing, and goal setting. Participants also receive 4 core modules addressing sleep-wake regularity, daytime functioning, correcting beliefs, and maintaining behavioral change. Additionally, 6 optional modules cater to specific sleep-wake patterns, addressing sleep efficiency, excessive time in bed, delayed/advanced sleep phase, sleep-related worry, complex sleep environments, and nightmares. Modules are delivered based on individual needs. Sessions include agenda setting, homework review, treatment content delivery, goal assignment, and session summarization.
