Abstract
Posttraumatic stress disorder (PTSD) occurs when significant intrusion, avoidance, and hyperarousal symptoms are manifest for at least 1 month following exposure to a traumatic event, with at least 1 month following exposure to a traumatic event, with at least 1 month elapsed betwenn the event and the diagnossis (Diagnostic and Statistical Manual of Mental Disorders, 4th edition, 1994 [DSM-IV]).Citation1 However, such symptoms are not necessarily manifest in the immediate aftermath of the trauman,Citation2 nor does their intial presence strongly predict who will develop PTSD.Citation3 One immediate response to trauma which has been convicingly linked to PTSD symptoms is peritraumatic dissociation.Citation4 In this poster, we briefly introduce a new scale assessing immediate responses distinct from peritraumatic dissociation, and we examine its power to predict PTSD symptoms.
