About this study
The overarching goal is to develop, refine and disseminate a comprehensive, easily accessible and effective Total Worker Health (TWH) program for wildland firefighters (WFF).
The term Total Worker Health® (TWH) (NIOSH) refers to the synergistic combination of 1) health promotion (e.g., healthy nutrition, exercise, restorative sleep), 2) worker safety issues, such as protective equipment and hazard control, merged with 3) work organization change to support and promote TWH.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Total Worker Health for Wildland FirefightersOther
The program is structured as 30-minute modules that can be done individually, with a partner, as a group or in a classroom setting. The six core modules are supplemented with eight elective modules. The program can be accessed on a smartphone, tablet or computer, and if needed can be downloaded as a pdf.
| Study group | Role | What they receive |
|---|---|---|
| Needs Assessment and Total Worker Health Program | Experimental | The initial phase was a needs assessment for wildland firefighters across segments and geographic locations to identify and prioritize program components. During the first phase, we recruited firefighters and collected baseline data in order to assess their needs using surveys for quantitative data and interviews and focus groups for qualitative data. The total worker health program includes 14, 30-minute modules on health topics highlighted during the needs assessment phase. Participants completed the program either individually or as part of a group. Receives: Other: Total Worker Health for Wildland Firefighters |

The second phase was to build a comprehensive, engaging TWH program for those fighting wildfires. It needed to be accessible on smartphone, tablet or computer, and suitable for individual, group and classroom settings. The final, third phase was to evaluate the program with a prospective proof-of-concept, usability and effectiveness trial among all types of wildland firefighters in different geographic locations.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The overarching goal is to develop, refine and disseminate a comprehensive, easily accessible and effective Total Worker Health (TWH) program for wildland firefighters (WFF).
The term Total Worker Health® (TWH) (NIOSH) refers to the synergistic combination of 1) health promotion (e.g., healthy nutrition, exercise, restorative sleep), 2) worker safety issues, such as protective equipment and hazard control, merged with 3) work organization change to support and promote TWH.
