Overcoming Insomnia: Impact on Sleep, Health and Work of Online CBT-I — NORSE-3  

Insomnia Clinical Trial

Official title:
Overcoming Insomnia: A Large-scale Randomized Controlled Trial of Online Cognitive Behavior Therapy for Insomnia Compared With Online Patient Education About Sleep.

Clinical Trial Summary

Insomnia is a major public health concern. While cognitive behavior therapy for insomnia (CBT-I) is acknowledged as the best available intervention, there are unanswered questions about its wider dissemination, socio-economic benefits and its impact on health resource utilization. The aim of this randomized controlled trial (RCT) is to investigate the effectiveness of a fully automated online version of CBT-I compared with online patient education about sleep (PE). Outcome measures comprise changes in symptoms of insomnia, time off work due to sick leave, as well as medication and health resource utilization. Also, we will examine putative mediators and selected potential psycho-bio-social moderators of the effects of the intervention.

Clinical Trial Description

This is a two-arm RCT that assesses the benefits of online CBT-I compared with an alternative, active control intervention (online patient education about sleep (PE)). We will randomize 1500 individuals and collect follow-up data for up to two years. First, we will examine any differential change in the severity of insomnia, immediately after completing the interventions. Secondly, we will examine if there are differential changes in symptoms of physical and mental health (e.g. psychological distress, fatigue, and health related quality of life) immediately post-intervention, and whether any improvements in insomnia or other symptoms are reported at further follow-ups (6- and 24 months post treatment termination). Third, we will use national registry data collected routinely in Norway to compare rates of time off work due to sick leave days for up to two years before and after participating in the RCT, as well as monitoring medication and health resource utilization according to condition in the same time interval. Fourth, we will try to extend the knowledge base about online interventions by undertaking exploratory analyses to assess whether change in specific clinical variables (e.g. sleep variability, psychological measures of beliefs about sleep) mediate the effects of the CBT-I intervention. Lastly, (subject to additional funding to collect saliva samples), we will examine a subset of psycho-bio-social factors to try to identify potential treatment moderators that might inform the stratification of individuals with insomnia into 'treatment-relevant' subgroups in the future (e.g. this may include also an exploration of 'therapygenetics'). ;
