Internet-delivered CBT for Insomnia: Role of Sleep-related Cognitions
- Conditions
- Insomnia
- Registration Number
- NCT01955928
- Lead Sponsor
- VU University of Amsterdam
- Brief Summary
The object of this study is to compare internet-delivered treatment for insomnia to a waiting-list. In this study participants are randomized to: 1) online cognitive-behavioral 2) waiting-list. Participants in the waiting-list condition receive treatment after the post-test. The interventions consist of: diary; psycho-education; relaxation exercises; stimulus control/sleep hygiene; sleep restriction; challenging the misconceptions about sleep; and paradoxical exercise. Adult persons with insomnia will be invited via a popular scientific website to fill out online questionnaires. Participants will fill out questionnaires and a dairy at baseline post-test, 3-month follow-up, and 6-month follow-up. In this study we are interested in sleep-related worry and daily complaints measured with a diary. We expect that the online intervention ameliorates both the sleep-related worry and the daily complaints. Furthermore, we expect that the sleep related worry mediates the effect of the intervention on sleep- and daily complaints.
