current sample was more representative of the general population than samples used in these previous studies, and Criterion A events and symptoms were measured using language reviewed by the DSM-5 Sub-work Group to operationalize the PTSD diagnosis. We also compared the draft PTSD criteria and text language of the DSM-5 with that used in the published DSM-5 (APA, 2013). Although there are some relatively minor changes in wording in the symptoms, the questions used in the National Stressful Events Survey are consistent with the finalized symptom descriptions. Therefore, we believe that findings from this study can be used to provide a reasonable preliminary estimate of PTSD prevalence within the U.S. adult population based on the DSM-5 criteria.
