Clinical Trial Summary

The proposed study will be a randomized, assessor-blind controlled trial embedding both outcome and process evaluations of a 6-week group LM intervention with/without self-tracking tools (Study I). The outcome evaluation will examine the effects of LM-S and LM alone vs. CAU, and the process evaluation will enhance the understanding of the causal assumptions that underpin LM to inform policy and clinical practice. Eligible participants with at least a moderate level of depression will be randomly assigned to the LM- S, LM alone, and CAU groups in a 1:1:1 allocation ratio. The study period will be 18 weeks. Assessments at baseline, week 7 (1-week post-intervention), and week 18 (12-week post-intervention) 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.

[Time Frame: Baseline, immediately after treatment, and 12 weeks after the treatment sessions are completed]
Secondary	Change in Insomnia Severity Index (ISI)	ISI is a 7-item scale designed to evaluate perceived insomnia severity.
