Brief summary
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.
Detailed description
Background: 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. Objective: This project aims to evaluate the efficacy and safety of Psychological First Aid for the prevention of PTSD and other post-traumatic disorders and/or symptoms. Population: Investigators will perform a 1:1 randomized-controlled trial of 200 adults recently affected (\<=72 hours) by a non-intentional trauma who consult to the emergency room of a public hospital. Investigators estimated a sample size of 200 individuals in order to detect a 50% Relative Risk Reduction (RRR), with a power of 80%, a statistical significance (alpha) of 5% and 34,4% of PTSD prevalence in the control group, what is consistent with prevalences observed in a similar sample by Fullerton, Ursano, Epstein, Crowley, Vance et al. (2001). Intervention: In the emergency room, undergraduate psychology students, previously trained and certified in PFA, will search and randomize suitable patients to either PFA or treatment as usual (TAU). They will provide PFA according to a protocol based on the WHO PFA Operation Guide to those patients included in the active group. Everyone correctly randomized will be followed and clinically evaluated one month after the intervention (endpoint).
Interventions
BEHAVIORALPsychoeducation
Participants in Control Group will be delivered a flyer named What can I do facing a crisis?, containing information about normal reactions to crisis, what to do to return to normal life and which are the signals of an initial trauma.
BEHAVIORALPsychological First Aid
Psychology students (PFA Providers) will intervene according to an adapted protocol based on the WHO PFA Operation Guide 2012. Protocol for this study contemplates 4 steps: 1. Active Listening 2. Relaxing and Breathing Techniques 3. Help in prioritizing needs 4. Help in contacting network and services. Moreover, participants in this group will receive a brochure with full contact information of public network, and a flyer named What can I do facing a crisis?.

Inclusion criteria
* Adults (≥ 18 years old) concurring to the emergency room, either as a patient himself or companion, who have been victims of a recent unintentional trauma (less than 72 hours ago), and meet one of the following criteria: * Direct victim, as a family or as a witness, of a situation that was or is currently life threatening. * Direct victim, as a family or as a witness, of a situation that affected or currently seriously endangers the physical integrity.

Will be the attending physician whom inform the patient if this exclusion criterion is met. * Relatives of people in imminent life-threatening or recently died in the emergency room where the offer to participate in the research can cause even greater discomfort. * Impairment of consciousness (Glasgow \< 15) * Intoxication * Loss of consciousness for more than 5 minutes. * Direct and indirect victims of intentional trauma (eg. assault, kidnapping, sexual abuse, terrorist attack, etc). * Patients being treated for a psychiatric disorder diagnosed by a doctor (personality disorder is excluded) (eg. schizophrenia, mental retardation, autism, obsessive compulsive disorder, bipolar disorder, depression, Alzheimer's disease, panic disorder, etc.).
