This study aims to conduct a randomized control trial to validate the treatment effect of e-based cognitive behavioral therapy for Insomnia (eCBT-I) on insomnia disorder, and explore whether eCBT-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 eCBT-I on prevention of depression and suicide.
Previous studies have documented the associations of insomnia with depression and suicide. Currently, researchers have done considerable work to investigate whether eCBT-I could be effective in improving psychological well-being for adults, and previous studies have confirmed that eCBT-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 eCBT-I might affect mental health, and whether eCBT-I could reduce the risk of depression and suicide.
This study will be the first specifically designed investigation of the preventive effects of eCBT-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 eCBT-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.
