RT Journal Article SR Electronic T1 Peer-based intervention for acute stress reaction: adaptations by five militaries JF BMJ Military Health JO BMJ Mil Health FD British Medical Journal Publishing Group SP 425 OP 429 DO 10.1136/military-2022-002344 VO 170 IS 5 A1 Adler, Amy B A1 Gutierrez, I A A1 McCuaig Edge, H A1 Nordstrand, A E A1 Simms, A A1 Willmund, G D YR 2024 UL http://militaryhealth.bmj.com/content/170/5/425.abstract AB Military service members need to be able to operate under conditions of extreme stress to ensure the success of their team’s mission; however, an acute stress reaction (ASR) can compromise team safety and effectiveness by rendering an individual unable to function. Building on an intervention originally developed by the Israel Defense Forces, several countries have developed, tested, and disseminated a peer-based intervention to help service members manage acute stress in others. This paper reviews how five countries (Canada, Germany, Norway, the UK and the USA) adjusted the protocol to fit their organisational culture while retaining essential elements of the original procedure, suggesting there can be interoperability and mutual intelligibility in the management of ASR by military allies. Future research should examine the parameters of effectiveness for this intervention, the impact of intervention on long-term trajectories, and individual differences in managing ASR.
