Although this debriefing is widespread, there is uncertainty about its impact on a person. Researchers Mayou, Ehlers and Hobbs (2000) were interested in evaluating the 3-year results of a randomized controlled debriefing study for successive subjects hospitalized following a road accident. Patients were assessed in hospital with the Impact of Event Scale (IES), the Letter Symptome Inventory (BSI) and a questionnaire, then reassessed after 3 years and 3 months. The intervention used was a psychological debriefing. The results showed that the intervention group had significantly worse psychiatric symptoms, travel fears, physical problems and financial problems. It should be ensured that the debriefing information corresponds to the information provided in the status quo communication. .
