Comment prevenir le trouble de stress post traumatique? Reflexion et application chez les professionnels à risques de la région Auvergne Rhône-Alpes.

Abstract : Post-Traumatic Stress Disorder (PTSD) follows exposure to one or more traumatic events and is characterized by a set of symptoms: flashbacks, avoidance, negative cognitive and affect changes, hyper-vigilance and sleep disturbance (American Psychiatric Association, 2013). The recent consideration of this disorder in the public sphere has highlighted the societal interest in acting upstream with professionals exposed to this type of event as part of their professional duties. The Auvergne Rhône-Alpes region has populations of professionals specialized in mountain environments (dangerous and unstable with sudden changes in weather conditions), who are particularly exposed to traumatic events (Weinbruch & Nordby, 2010). As a result, they are more likely to develop PTSD than the general population.The aim of this thesis work was to provide elements to establish the lines of action to be adopted to improve the resilience capacities of at-risk professionals in order to prevent PTSD in the early stages. Through an integrative and processual approach to PTSD development focused on a biopsychosocial perspective, we studied a set of factors involved in the development and/or persistence of this disorder and coupled with the construction, evaluation and implementation of preventive action.The results of the laboratory and on-site studies revealed the involvement of a set of both specific and general factors (i.e., coping flexibility, physiological regulatory mechanisms, meaning of the mission). We can thereby conclude that this disorder is the result of a translational interaction defined by strong interconnection between psychology and physiology, and by the socio-professional environment that modifies the expression and visibility of this disorder. This thesis proposed new elements to prevent professional TSPT, based on an integral and multifactorial vision with an evidenced-based approach. In conclusion, these studies are the first to address primary prevention of PTSD with an integrative approach.
