The symptom structure of PTSD in simple and complex trauma type groups

The present study aimed to examine the structure of posttraumatic stress disorder (PTSD) symptoms in simple and complex trauma. Sample consisted of 428 simple trauma group and 207 complex trauma group in Korean adults aged over 18 who had experienced at least one traumatic event in their life time. We assessed their PTSD symptoms using Posttrauma Diagnostic Scale (PDS), and tested five models consisting of PTSD symptom factors based on the DSM-IV criteria as well as those from the previous studies. Confirmatory factor analyses were conducted on each of the five models of the PTSD symptoms. Among the five models, the four factor intercorrelated model with re-experiencing, avoidance, emotional numbing and hyperarousal factors provided the best fit in both simple and complex trauma groups. Results are discussed regarding the implications of this finding.
