RecruitingBehavioural interventionReducing Posttraumatic Stress Disorder (PTSD) Symptoms in First Responders and Frontline Health Care WorkersThis study addresses PTSD symptoms in First Responders and Healthcare workers. Specifically, it tests whether a brief PTSD treatment (talk therapy) effectively treats PTSD when provided to First Responders and Healthcare workers by counselors in Employee Assistance Programs (EAPs). The central hypothesis is that the PTSD treatment, Prolonged Exposure for Primary Care (PE-PC), will reduce PTSD symptoms and improve functioning, compared to EAP Treatment as Usual (TAU).
