Summary

The proposed parallel-group randomized controlled trial add-on superiority of the iCBT-I program with CAU as a control condition will let us investigate the effectiveness and cost-effectiveness of iCBT-I. Analysis of baseline characteristics of the participants aims to find predictors of outcome

Detailed description

Application of internet-delivered cognitive-behavior treatment for insomnia (iCBT-I) is a perspective method that can fill the gap created by the discrepancy between insomnia cases and the number of trained professionals. Although the effectiveness of this method was proven in multiple studies conducted in research settings, it is unclear if iCBT-I outperforms pharmacotherapy which remains a widely used alternative of cognitive-behavior therapy of insomnia (CBT-I). Predictors, mediators, and moderators of treatment effect remain uncertain since previous studies often give contradictory results. The present study aims to investigate clinical effectiveness and cost-effectiveness of an internet-based CBT-I program Sleepsy in comparison with care as usual (CAU) among patients with chronic insomnia (CI) recruited from clinical settings. Baseline data will be further analyzed to find predictors of treatment outcome For these purposes, a parallel-group randomized controlled trial add-on superiority of the iCBT-I program with CAU as a control condition was designed. 110 participants will be referred from the medical doctors in Moscow. Both groups will have access to CAU, treatment prescribed by the referred doctor. Patients of the first group will additionally get access to the iCBT-I program with the opportunity to contact a specialist within the program (guidance on request) in a secured environment. The primary outcome is insomnia severity change from pre- to posttreatment and to post-follow-up. Secondary outcomes include change subjective sleep characteristics, daytime symptoms, comorbid affective disorders, dysfunctional cognitions and behavior, healthcare consumption, and productivity losses. Predictors analysis will include baseline scores of the aforementioned outcomes along with treatment expectancies, personality traits To the best of our knowledge, the present study is the first study of iCBT-I to be conducted in clinical settings. We expect that this approach lets us determine the target group more precisely and exclude health problems that may interfere with treatment. It is also expected that patients, referred to iCBT-I from the doctor's office will be more motivated to finish the treatment course that will reduce the drop out rate. CAU as control condition let us reconstruct clinical situation facing practicing doctor. On the other hand, CAU may result in a loss of power to detect a meaningful difference. Limitation of our study is in the impossibility of blinding participants to the treatment condition

Conditions

• Chronic Insomnia

Interventions

Type	Name	Description
BEHAVIORAL	internet-delivered cognitive-behavioral therapy for insomnia (iCBT-I)	The 2-month intervention consists of educational material divided into 8 modules, which provide the rationale for the CBT-I interventions: sleep restriction; stimulus control; cognitive techniques; relaxation techniques. Information is presented in 10-minute videolectures. The program includes a sleep diary to insert bedtime and waketime, sleep latency, total sleep time, night awakenings. All material will be delivered through the internet program and expected to be elaborated by the patient but with the opportunity to contact a specialist via the feedback form (guidance on request) in a secured environment if they face difficulties or possible negative effects of the intervention. The content of the program is based on an already established internet-based self-help program against insomnia that was already tested in a previous study.
OTHER	Care as usual (CAU)	Intervention includes all variety of therapy methods that can be prescribed by medical doctors (MD): pharmacotherapy, behavioral recommendations, face-to-face psychotherapy. Prescriptions may be made during the first visit to MD, or at any point in the study on a next doctor visit, or during visits to the doctors of other medical centers. All concurrently applied treatments will be assessed repeatedly by self-report
