Attachment theory models the emotional bonding that is activated in situations of danger, via mental representations of self and others. Four types of attachment (TA) exist in adults: 3 insecure (Preoccupied, Detached, Fearful) and 1 secure. Attachment type is a major factor in the development of Post-Traumatic Stress Disorder (PTSD), a frequent and disabling mental disorder that occurs after a traumatic event. A meta-analysis based on Anglo-Saxon studies including various populations (general, military or clinical) (n=9268 patients) suggested an association between Fearful BP and high level of PTSD symptoms (r=0.44). Nevertheless, these results did not allow the identification of variations related to the individual risk factors (RDFs) of the subject and his environment, especially in the French socio-cultural context. The investigators propose to study the association between LDs and the risk of PTSD in the days following exposure, their mutual influence in the months following, and their associated factors. Thus, a prospective cohort study among French adult victims of a traumatic event could objectify the link between BP - as close as possible to the event - and the risk of PTSD.
