Brief Summary

Insomnia is one of the most common sleep disorders and affects approximately 10 - 40% of the population across different age groups in Hong Kong. Cognitive behavioral therapy for insomnia (CBT-I) is the first line treatment for adult insomnia due to its comparable effect to medication in short term but is more sustainable in the long run. However, only a few sufferers have received CBT-I, due to limited accessibility, lack of trained sleep therapists, time costing and geographical limitations. To increase CBT-I accessibility, different formats of CBT-I have been proposed. Empirical evidence including ours consistently suggested that self-help digital CBT-I is effective in improving sleep while its augmentation with a guided approach could further enhance the treatment gain. Previous evidence has suggested that although self-help CBT-I could lead to positive outcomes, the drop out rate is quite high and maybe less effective for patients with comorbidity or high level of distress. Thus, a stepped-care approach to CBT-I that utilizes online self help and therapist-guided modes of delivery might be a potential way to facilitate efficient dissemination of effective insomnia treatment resources. The effectiveness of the stepped care model will be evaluated in a real world setting using stepped-wedge cluster randomized controlled design. The program will be rolled out to different districts in Hong Kong sequentially in 18 districts over 4 steps with a eqaully spaced time periods.

Secondary Outcomes (11)

  • Severity of depression

    Post-intervention (ranging from 8 weeks to 24 weeks, depending on the treatment level), 3-month post-intervention and 12-month post-intervention follow up

  • Severity of anxiety

    Post-intervention (ranging from 8 weeks to 24 weeks, depending on the treatment level), 3-month post-intervention and 12-month post-intervention follow up

  • Health-related quality of life

    Post-intervention (ranging from 8 weeks to 24 weeks, depending on the treatment level), 3-month post-intervention and 12-month post-intervention follow up

  • Chronic insomnia diagnosis

    Post-intervention (ranging from 8 weeks to 24 weeks, depending on the treatment level), 3-month post-intervention and 12-month post-intervention follow up

  • Medication usage

    Post-intervention (ranging from 8 weeks to 24 weeks, depending on the treatment level), 3-month post-intervention and 12-month post-intervention follow up

  • +6 more secondary outcomes

Study Arms (2)

Stepped-care CBT-I group

EXPERIMENTAL

A total of 3 steps of CBT-I intervention will be provided, with the objectives to increase the awareness of sleep health, increase sleep literacy, establish good sleep hygiene and treat insomnia. Step 1: self-help digital CBT-I program; Step 2: guided CBT-I program; Step 3: individualized consultation.

Behavioral: Cognitive behavioral therapy for insomnia (CBT-I)

Control group

NO INTERVENTION

Participants in the control group remain unexposed to the stepped-care CBT-I intervention.

Interventions

CBT-I intervention will be provided to participants once their districts are exposed.
