Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to conduct a randomized control trial to validate the treatment effect of e-based cognitive behavioral therapy for Insomnia (e-CBT-I) on insomnia disorder, and explore whether e-CBT-I could prevent depression and suicide in youths with insomnia and subclinical depression. In addition, to further explore the mechanisms underlying the association between insomnia treatments and psychiatric disorders, this study will evaluate whether changes in candidate factors including insomnia symptoms, poor sleep hygiene, sleep-related unhelpful thoughts and maladaptive behaviors, circadian rhythm disruption and chronic sleep deprivation will mediate the effect of e-CBT-I on prevention of depression and suicide.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Previous studies have documented the associations of insomnia with depression and suicide. Currently, researchers have done considerable work to investigate whether e-CBT-I could be effective in improving psychological well-being for adults, and previous studies have confirmed that e-CBT-I is effective in reducing depressive symptoms and suicidal ideation in adult population.

However, such studies have not been established in youths yet. Additionally, it is still unclear that by which mechanisms e-CBT-I might affect mental health, and whether e-CBT-I could reduce the risk of depression and suicide.

This study will be the first specifically designed investigation of the preventive effects of e-CBT-I for depression and suicide in youths, and the first large scale causal test of the relationship between insomnia treatments and psychiatric disorders. The results can be expected to influence care provision for the youth population who are at a life stage of emerging adulthood and vulnerable to psychiatric disorders. Further, because the investigators will be using an e-CBT-I approach, a scalable solution may be demonstrated as both feasible and effective. The findings of this study will show the possibility of developing novel preventive intervention for depression and suicide by targeting insomnia.

E-based cognitive behavioral therapy for insomnia (e-CBT-I)

The e-CBT-I will be delivered by a mobile application (eSleep) developed by BestCare \& SuMian BioTech Co., Ltd. which contains a digital, self-paced, and highly interactive programme. It consists of six weekly sessions with animated elements, including an overview of sleep, sleep restriction, stimulus control, cognitive therapy, structured worry time and relapse prevention. Participants will have access to the e-CBT-I treatment for 12 weeks.

Group Type EXPERIMENTAL

e-CBT-I

Intervention Type BEHAVIORAL

The e-CBT-I will be delivered through a mobile application (eSleep) with a personal password.

E-based health education (e-HE)

The e-HE, a psychoeducation/information-approach, also consists of six consecutive sessions which contains information about general sleep knowledge, functions of human organs, nutrition, environmental health, brain health, identification and treatments of common diseases, but the contents are not related to any active therapeutic components of cognitive behavioral therapy for insomnia (CBT-I). Participants will have access to the intervention for 12 weeks.

Group Type ACTIVE_COMPARATOR
