Clinical Trial Summary

This experimental study aims to develop an internet-based self-help cognitive behavioural therapy for insomnia that reduces insomnia symptoms and its associated adverse outcomes among people with sub-threshold insomnia symptoms. In particular, this study compares the efficacy of internet-delivered self-help CBT-I with the wait-list control group, in treating insomnia in a non-clinical population. The online CBT-I course will consist of an introductory module, followed by 6 weekly modules. Each module will consist of the main treatment component presented in written or video format, quiz, and homework. Materials will be presented in an interactive manner to facilitate engagement.


Clinical Trial Description

Although the Internet self-help CRT-I program have shown promising effect on dealing with insomnia symptoms, the effectiveness of internet self-help CBT-I in adults with sub-clinical insomnia symptoms in Hong Kong is under-studied. Therefore, the present study aimed to compare the efficacy of internet-delivered self-help CBT-I with the wait-list control group, in treating insomnia in a non-clinical population. We hypothesized that (1) participants who received CBT-I treatment would have improved insomnia symptoms after the intervention as compared with the wait-list controls; (2) participants from CBT-I would have better sleep hygiene, and less dysfunctional beliefs about sleep and pre-sleep arousal after the intervention as compared with the wait-list controls; (3) participants from CBT-I would have improved mental health, daytime functioning, quality of life, and general well-being after treatment, as compared with the wait-list controls. The online CBT-I course will consist of an introductory module, followed by 6 weekly modules, incorporating the key CBT-I components, including sleep hygiene education, stimulus control, sleep restriction, relaxation training, and cognitive therapy. Each module will consist of the main treatment component presented in written or video format, quiz, and homework. Materials will be presented in an interactive manner to facilitate engagement. ;
