Brief Summary

Background: Insomnia is a common mental problem, where people experienced difficulty falling asleep, problem maintaining asleep and early morning awakening. It is highly prevalent world-wide and in Hong Kong, causing significant suffering and distress. While evidence based intervention exists, e.g. cognitive-behavioural therapy (CBT), there will not enough therapists to meet treatment demand. A more efficient delivery of treatment, e.g. internet based therapy is called for that can delivery treatment more cost efficiently by requiring lesser therapist time. Objective: This study aims at evaluating the effectiveness of CBTi (Gp) on treating Chinese insomniac adults in Hong Kong. There has been criticism that most clinical trials have been conducted with Caucasians in Western countries and little has been done with ethnic minorities, including Asians in these countries, not to mention Asians in Asian countries, e.g., Chinese in Hong Kong. Design: A two-arm parallel-group randomised controlled trial, comparing the treatment and waitlist group Method: A CBTi protocol would be developed. Approximately 60 Chinese adults with insomnia will be recruited in Hong Kong and randomised into one of the two groups (treatment vs. waitlist). The treatment last for 6 weeks, plus a 3-month follow-up period. The primary outcome measure will be Insomnia Severity Index (ISI).

Outcome Measures

Primary Outcomes (1)

  • Change in Insomnia Symptom Inventory (ISI) (Bastien et al, 2001)

    A 7-item self-report questionnaire assessing the nature, severity and the impact of insomnia. Insomnia Symptom Inventory is the primary outcome measure. All items are assessed on a 5-point scale (0-4), with its total score ranging between 0 to 28. Higher score representing worse insomnia symptoms.

    Change from baseline Insomnia Symptom Inventory at 3 months

Secondary Outcomes (4)

  • Change in Dysfunctional Beliefs about Sleep Scale (DBAS) (Morin et al, 2007)

    Change from baseline Dysfunctional Beliefs about Sleep Scale at 3 months

  • Change in Patient Health Questionnaire 9 (PHQ-9) (Kroenke & Spitzer, 2002)

    Change from baseline Patient Health Questionnaire 9 (PHQ-9) at 3 months

  • Change in Generalized Anxiety Disorder-7 item (GAD-7) Questionnaire (Spitzer et al, 2006)

    Change from baseline Generalized Anxiety Disorder-7 item (GAD-7) Questionnaire at 3 months

  • Change in Work and Social Adjustment Scale (WSAS) (Mundt et al, 2002)

    Change from baseline Work and Social Adjustment Scale at 3 months
