Clinical Trial Summary

The goal of this randomized controlled trial is to test the effectiveness of digital cognitive behavioral therapy for insomnia (dCBT-I) compared with digital patient education about insomnia for people with Multiple Sclerosis (MS). The main questions it aims to answer are whether dCBT-I is effective in reducing insomnia severity in people with MS, whether dCBT-I is effective in reducing daytime fatigue, psychological distress, cognitive problems, medication use (hypnotic, sedative/anxiolytic and antidepressant), resource utilization and if these changes are mediated by improvements in insomnia severity and whether dCBT-I is feasible for people with MS

Description:

Insomnia is prevalent among individuals with Multiple Sclerosis (MS). Improving sleep is an important therapeutic goal, but there is currently a lack of effective treatment options. Cognitive Behavioral Therapy for Insomnia (CBT-I) has been widely studied in other patient groups and is currently recommended as first- line treatment for chronic insomnia. Overall, the availability of CBT-I has been limited, as the number of patients in need of treatment far exceeds the number of available therapists. Therefore, fully automated digital adaptations of CBT-I (dCBT-I) have been developed that contain both screening and intervention. Whether this treatment is effective for a clinical sample of patients diagnosed with MS, or if improved sleep can lead to improved daytime functioning in MS, is however, currently unknown. This is a novel approach to a digital treatment of a common disorder in MS, and that may result in improved implementation of a low-threshold intervention.

Intervention

Behavioral:
• Digital Cognitive Behavioral Therapy for Insomnia (dCBT-I)
dCBT-I during 9 weeks. Multicomponent intervention that includes the following: psychoeducation about sleep, sleep hygiene, sleep restriction therapy, stimulus control and challenging beliefs and perception about sleep. The digital CBT-I that will be utilized in this study is named Sleep Healthy Using The internet (SHUTi). The intervention is fully automated with no contact with health care personnel, it is interactive and adapts to input from the users. It comprises of the same elements included in face-to-face CBT-I, but the user gains access to a new educational, behavioral or cognitive module each week only after completion of digital sleep diaries. dCBT-I can be accessed on computers or hand-held devices
• Digital patient education about insomnia (PE)
Control condition PE during 9 weeks. A digital patient education program that can be accessed on computers or hand-held devices. The information overlaps with that included in the dCBT-I intervention but it does not include any of the interactive features of the dCBT-I intervention and all the information is available from the moment the PE site is opened.
