What this trial studies

This study evaluates the effectiveness of a self-help book designed to help individuals cope with shift work-related problems compared to standard sleep hygiene advice. A total of 300 participants with shift work disorder will be randomly assigned to receive either the self-help book or sleep hygiene guidance. Participants will complete questionnaires assessing their sleep quality, sleepiness, and overall health at the start and six months after the intervention. The primary goals are to determine if the book leads to greater improvements in sleep issues and overall health compared to traditional advice.

Why it matters

Potential benefit: If successful, this intervention could significantly improve the quality of life for individuals suffering from shift work disorder.

How similar studies have gone: While there have been various interventions for shift work disorder, the specific use of a self-help book as a primary intervention is relatively novel.
