RESCUE- expected usefulness and willingness to participate in a trauma-informed group intervention for coping with traumatic work experiences in the emergency medical services.

Emergency Medical Services personnel (EMS) are confronted with potentially highly stressful and traumatic occupational experiences, placing them at high-risk for mental disorders. Avoidant coping mechanisms, internalized and occupational stigma not only impede disclosure of and processing the incident-related stress but also weaken the overall resilience of the EMS. Effective interventions are needed that operate both at the individual and group level. The aim of this study was to investigate the expected usefulness and willingness to participate in a trauma-informed intervention (Facts derived from Narrative Exposure Therapy, NETfacts). A total of 256 German EMS (67.19% men, 32.81% women) participated in the online survey. We assessed the expected usefulness and willingness to participate in NETfacts, critical incident-related stress (EMS Critical Incident Inventory EMS-CII), burnout symptoms (Professional Quality of Life ProQOL), age and work experience. Overall, about half of the EMS expected NETfacts to be at least somewhat useful, and reported a generally willingness to participate. Expected usefulness was neither associated with critical incident-related stress nor burnout symptoms. Younger participants (<35 years) showed a generally higher willingness to participate than older participants. However, the willingness is across both age groups positively associated with higher levels of critical incident-related stress. Nevertheless, burnout symptoms and the willingness are negatively associated among participants age 35 and older, while remaining stable among their younger colleagues. Early, trauma-informed and age-sensitive prevention programs are needed to mitigate the adverse effects of critical incidents among EMS. Our study presents EMS preferred circumstances to enhance employees' uptake of such a program.
