CompRest - a Comparison Between Sleep Compression and Sleep Restriction for Treating Insomnia
CompRest - a Comparison Between Sleep Compression and Sleep Restriction for Treating Insomnia
This study includes two consecutive sub-trials.

 Cognitive Behavioral Therapy (CBT) is treatment of choice for Insomnia. One of the most
 important treatment Components in CBT for insomnia (CBT-i) is Sleep Restriction (SR), but
 lately, adverse effects related to SR have been reported. A treatment method with
 similarities to SR is Sleep Compression (SC). SC is not as well studied as SR, but appears to
 have similar effects to SR but without the adverse effects. The first sub-trial thus aims at
 directly comparing SR and SC. The second sub-trial aims at evaluating any additional effects
 of CBT-i components given as an add-on treatment to a randomized selection of half
 participants in each original treatment arm.
