N2 - Empirical data have challenged chronic posttraumatic stress disorder (PTSD) consisting of three dimensions. In the present Study we aimed to determine the factor structure of acute posttraumatic symptoms in two recently traumatized samples. In sample 1, 203 civilian trauma survivors were administered the Davidson Trauma Scale (DTS) approximately 1 week posttrauma in sample 2, 182 civilian treatment seeking trauma Survivors completed the DTS at all average of 41.4 days posttrauma. Our confirmatory factor analyses indicated that a 4-factor intercorrelated model provided the best representation of the data in both samples. The four factors are best described as reexperiencing, active,avoidance, dysphoria, and hyperarousal. For acute posttraumatic symptoms, the empirical data suggest to split the avoidance Cluster into 'Active avoidance' and 'Dysphoria'-confirming findings ill Studies on chronic PTSD. In future revisions of the DSM, the diagnostic criteria for PTSD may need to be adapted to fit the research findings. (C) 2009 Elsevier Ltd. All rights reserved
