Psychological First Aid (PFA): RCT Adults Non-intentional Trauma Emergency Room

Psychological First Aid (PFA) is currently the most recommended early intervention for people affected by recent traumatic events, especially in the aftermath of natural disasters. Unfortunately, there is no evidence that PFA neither prevents Post-Traumatic Stress Disorder (PTSD) nor other post-traumatic disorders or symptoms of distress. This project aims to evaluate the efficacy and safety of Psychological First Aid for the prevention of PTSD and other post-traumatic disorders or symptoms.
