Sleep Well Firefighters: An App-based Program to Improve Sleep, Cognition, and Behavioral Health in Firefighters

This study is testing an app-based program called "Sleep Well Intervention Group" to see if it can help firefighters improve their sleep, thinking skills (cognition), and overall mental well-being. You might be able to join if you are a CalFire Wildfire firefighter in the Central Coast region or a City of San Luis Obispo Firefighter, speak English, have an iPhone/iPad, are at least 18 years old, and are interested in improving your sleep. The study aims to find out if this program is practical and acceptable for firefighters. The current status of this study is unclear.

Study design
This is an interventional study with a planned enrollment of 50 participants. It compares an app-based sleep program to standard sleep education materials.
What's involved
You would complete questionnaires, wear a wrist device to track sleep, and either use a mobile app with monthly coaching calls for three months or receive basic sleep education materials. After three months, you would repeat the initial assessments.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed from baseline through study completion, which is 12 weeks.
