[Post-traumatic stress disorder and psychological debriefing: a controversial topic].

The last decades have demonstrated the value of early interventions after a traumatic event. The purpose of these interventions is to prevent the development of psychological consequences such as post-traumatic stress disorder. Psychological debriefing is clearly the most popular intervention. However, in the literature, it is subject to a real controversy. The objective of the present paper is to define the interest of psychological debriefing, but also alternative therapeutical strategies for people exposed to traumatic events.
