The effect of a self-help book for shift work disorder – A randomized controlled trial
Main content
Sleep problems related to shift work are common. Shift work disorder is a circadian rhythm sleep disorder that is characterized by insomnia and/or increased sleepiness due to a work schedule that overlaps with the habitual sleep time. The prevalence varies within different work schedules but is most common among rotating shift workers. The treatment is directed towards the sleep and sleepiness problems experienced by the shift worker and at the circadian rhythm disorder itself. Non-pharmacological treatment is recommended for sleep problems.
The main objective of this RCT study is to evaluate whether a self-help book to cope with shift work can reduce the prevalence of shift work-related sleep disorders, increase knowledge about sleep and circadian rhythms, provide better health and reduce "turnover intention" among health workers who experience these sleep problems. The self-help book for coping with shift work is written especially for shift workers struggling with night- and shift work. The book presents knowledge about sleep regulation and circadian rhythms. Based on this, the book provides specific advice on how to cope with different types of shift work. A total of 300 health care workers with shift work disorder will be recruited and randomized into two groups; one group (n = 150) receiving the self-help book and one group (n = 150) receiving sleep hygiene advice. Participants will answer a questionnaire at baseline and after 6 months. After the follow-up period, the participants in the control group will also receive the book.
If the self-help book proves to be effective, this may be an easy and inexpensive way to help shift workers who are struggling with shift-related sleep problems.
The University of Bergen has prepared the framework for the study. The project is supported by the Norwegian Research Council (NFR) and the University of Bergen and is approved by the Regional Committee for Medical and Health Research Ethics (REK).
