Description of intervention(s) / exposure
The Mind-Body Tactical Resilience Training Program is developed by YogaShield® Yoga For First Responders® (YFFR). YogaShield® YFFR is a non-profit organization based in Colorado, United States that delivers this tactical resilience training to first responders using mind-body techniques that are job-specific and culturally informed. Members of the organisation consist of active and former first responders, military, as well as yoga instructors. The aim of this training is to equip first responders with a proactive and tactical skillset for processing stress, building resilience, and enhancing performance using a methodology that is job specific and culturally informed. To the best of our knowledge, this is the most well-established tactical mind-body resilience training program for first responders in the world. Given the scale and reach that the organisation has already achieved with local networks as well as throughout the U.S. and internationally, collaborating with YFFR and their first responder networks in the U.S. is an ideal location to undertake analysis on the effectiveness of this type of training.

The Mind-Body Tactical Resilience Training consists of a free-of-charge program comprising sixteen 60-minute classes delivered between approximate 8 - 16 weeks (depending on shift schedules) by trained YFFR instructors, and within the department’s training facility. The aim of this training is to equip first responders with a proactive and tactical skillset for processing stress, building resilience, and enhancing performance using a methodology that is job specific and culturally informed. The training utilizes a variety of specialized techniques including tactical breathwork, physical drills, mindfulness and self-regulation strategies. Classes will be scheduled with each department’s training chief to ensure accessibility for participants to attend as many in-person classes as possible. Adherence will be monitored using attendance records.

Efficacy
Statistical methods / analysis
Primary analyses will be undertaken within an intention-to-treat framework, retaining all participants as randomised regardless of extent of engagement with training or withdrawal from the study. Likelihood based methods (mixed-model repeated measures (MMRM) will be used to assess significance of change in the primary outcome measures. Clustering of each shift of participants will be accounted for by a random cluster membership factor, and an unstructured variance–covariance matrix will be used to accommodate the relationships between observations at the three different measurement timepoints, from baseline (T1) to the final 3-month follow up (T3). Stratification variables and any variables found to be substantially imbalanced between intervention arms post randomisation will be tentatively included in these models and retained if statistically significant and influential on outcomes. Additional per-protocol analysis using data for those who successful complete baseline and the follow-up assessments will also be conducted.

Secondary analyses will also include, but are not limited to, controlling for baseline symptoms to measure differential intervention effects, as well as analyses of secondary outcomes assessing differential change due to the intervention arm.
