Insufficient sleep is a significant public health issue, particularly affecting shift workers like firefighters, nearly half of whom report short or poor-quality sleep, with 35-40% screening positive for sleep disorders. Cognitive Behavioral Therapy for Insomnia (CBTi) is a recommended and effective treatment, but access to such interventions remains low. This study will recruit 20 fire agencies in Arizona (400 firefighters) to test if a CBTi-informed intervention, including sleep health coaching and agency-wide promotion, improves sleep more effectively than usual care. The trial will also explore factors that influence successful implementation across agencies.
