NCT07494617

Brief Summary

The goal of this clinical trial is to evaluate the impact of short documentary-style videos to educate and inspire firefighters to take safety measures to prevent cancer incidence and mortality. The main question it aims to answer is: Will firefighters will have a higher perceived susceptibility to cancer, lower perceived barriers to cancer risk reduction practices, and higher perceived self-efficacy and benefit to risk reduction practices after watching the videos? Participants will:

  • Take a Pre-Intervention survey
  • Watch one of five randomly assigned 5 minute video interventions
  • Take a Post-Intervention survey
