The aim is to assess whether a self-help book for insomnia will improve sleep and reduce hypnotic use among patients on sleep medications.
This study is a randomized controlled trial evaluating the effect of a self-help book for insomnia compared to the effect of sleep hygiene advice in patients using sleep medications. 150 patients will be randomized to receive either the book (75 patients) or the sleep hygiene advice (75 patients). Patients will fill questionnaires about sleep and health problems at baseline and after 3-6 months after receiving the written material. The main aims are to assess whether a self-help book is more effective in reducing sleep medication use and sleep problems.
