Abstract
The Diagnostic and Statistical Manual of Mental Disorders (4th edition; DSM-IV) conceptualization of posttraumatic stress disorder (PTSD) includes three symptom clusters or sequelae: reexperiencing, avoidance/numbing, and hyperarousal. The PTSD Checklist–Civilian Version (PCL-C) is based on the DSM-IV criteria. In the current study, we conducted an exploratory factor analysis (EFA) of the PCL-C using a sample of 312 adults. We examined whether the Greek adaptation of the PCL-C evidenced the three-factor solution given by the DSM-IV symptom cluster or the four-factor solution implied in other studies. The EFA was used to extract three- and four-factor solutions. The EFA identified a three-factor solution that included reexperiencing, avoidance/numbing, and hyperarousal supporting the DSM-IV PTSD symptoms.
