Peer delivered, emotion regulation-focused mental health prevention training for fire fighter trainees: Design and methodology of a randomized controlled trial.

UNLABELLED

Fire fighters (FFs) risk their lives, health, and well-being through trauma exposure and other occupational stressors. FFs report concerning rates of mental health challenges, alcohol use disorders, and suicide risk. These problems tend to co-occur, as each is linked with reliance on maladaptive emotion regulation strategies. As FFs advance in their careers, many tend to rely more heavily on these maladaptive emotion regulation strategies, thus exacerbating the problems. Many FFs leave fire service prematurely due to mental and physical health problems. FFs must be equipped with more effective emotion regulation skills to buffer against stressors they will face. FFs may benefit from training in transdiagnostic emotion regulation skills delivered by credible peers upon entry and socialization into the profession, potentially preventing substantial negative outcomes downstream while promoting resilience and wellness. This paper describes a cluster randomized controlled trial to compare peer-delivered emotion regulation training with peer-delivered psychoeducation regarding mental health, both delivered during the fire academy, for preventing symptoms of PTSD (primary outcome), depression, anxiety, alcohol use disorder, and functional impairment. Emotion regulation training is based on the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders. Participants will be a non-clinical population of FF trainees completing the fire academy at 10-12 cities nationwide ( = 312). Participants will be cluster randomized to training condition by recruit class. Subsequent recruit classes will then alternate between conditions within each city. Assessment measures will be administered at pre-training baseline, post-training, and at 6-, 12-, 18-, and 24 month follow-ups.
