The effect of group-based cognitive behavioural therapy for insomnia in patients with rheumatoid arthritis: a randomized controlled trial
Primary result · Sleep efficiency (PSG)Result — go to the resultDifference 5.03 95% CI −0.37 to 10.43Authors' conclusion
Nurse-led group-based CBT-I did not lead to an effect on sleep efficiency objectively measured with PSG. However, CBT-I showed improvement on all patient-reported key secondary sleep- and RA-related outcomes measured at week 26.
Study context
- Population
- Patients with RA and insomnia (89% women, average age 58 years, average sleep efficiency 83.1%)ITT population
- Participants
- 62 patients
- Comparison
- 6 weeks' nurse-led group-based cognitive behavioural therapy for insomnia (CBT-I) vs usual care
- Primary endpoint
- Sleep efficiency measured by PSG immediately after the intervention
- Follow-up
- Week 7
