Brief Summary

This study will examine the use of a transdiagnostic Sleep and Circadian Treatment (TranS-C) in treating Major Depressive Disorder (MDD) in Chinese adults. Sleep disturbance is highly comorbid with a range of psychological disorders, especially MDD. MDD is a major public health concern and a leading cause of disability worldwide. A shift in treatment perspectives, from a disorder-specific approach to a transdiagnostic approach, has been proposed. While the disorder-specific approach tends to understand and treat different mental disorders as independent psychological problems, the transdiagnostic approach aims to identify common clinical features (e.g. sleep disturbances) across a range of psychological disorders. The transdiagnostic approach would potentially facilitate timely dissemination of evidence-based psychological treatments and contribute to significant public health implications. This study will be a pilot randomized controlled trial on the efficacy of TranS-C for MDD. TranS-C integrates elements of evidence-based interventions, namely cognitive-behavioral therapy for insomnia, delayed sleep phase type, and interpersonal and social rhythm therapy. Prior to all study procedures, an online informed consent (with phone support) will be obtained from potential participants. Around 40 eligible participants will be randomly assigned to the TranS-C group or the care-as-usual control group (CAU group) in a ratio of 1:1. The randomization will be performed by an independent assessor using a computer-generated list of numbers. No deception is necessary. Participants in the TranS-C group will receive TranS-C once per week for 6 consecutive weeks respectively. The group treatment will be delivered by a clinical psychology trainee under the supervision of a clinical psychologist. The TranS-C group will complete a set of online/paper-and-pencil questionnaires before the treatment commences, 1-week, and 12-week after the treatment sessions are completed. The CAU group will complete the same set of online/paper-and-pencil questionnaires during the same periods.

Outcome Measures

Primary Outcomes (1)

  • Change in the Patient Health Questionnaire (PHQ-9)

    The PHQ-9, a 20-item questionnaire used for screening, diagnosing, monitoring and measuring the severity of depression, which scores each of the nine DSM-IV criteria as "0" (not at all) to "3" (nearly every day). PHQ-9 scores of 5, 10, 15, and 20 represents mild, moderate, moderately severe and severe depression

    Pre-treatment, 1-week post-treatment and 12-week post treatment

Secondary Outcomes (6)

  • Change in Hospital Anxiety and Depression Scale (HADS)

    Pre-treatment, 1-week post-treatment and 12-week post treatment

  • Change in Insomnia Severity Index (ISI)

    Pre-treatment, 1-week post-treatment and 12-week post treatment

  • Change in 7-Day Sleep Diary

    Pre-treatment, 1-week post-treatment and 12-week post treatment

  • Change in Multidimensional Fatigue Inventory (MFI)

    Pre-treatment, 1-week post-treatment and 12-week post treatment

  • Change in Short Form (Six-Dimension) Health Survey - The Chinese (Hong Kong) Version (SF-6D)

    Pre-treatment, 1-week post-treatment and 12-week post treatment

  • +1 more secondary outcomes

Other Outcomes (1)

  • Change in Credibility-Expectancy Questionnaire (CEQ)

    Pre-treatment, 1-week post-treatment and 12-week post treatment
