![]() ![]() Our study also indicates the importance of individual perception of life threat in the prediction of PTSD. Conclusions: Our results indicate that the current DSM-5 definition of trauma, although a slight improvement from DSM-IV, is not highly predictive of who develops PTSD symptoms. ![]() Self-reported fear for one's life significantly predicted PTSD symptoms. For DSM-5, effect sizes were slightly larger but still nonsignificant (except for significantly higher hyperarousal following traumas vs. Results: There were no significant differences between DSM-IV-defined traumas and stressors. Events were rated for whether they qualified as DSM-IV and DSM-5 trauma. Method: One hundred six women who had experienced a trauma or significant stressor completed questionnaires assessing PTSD, depression, impairment, and event characteristics. Further, we examined theoretically relevant event characteristics to determine whether characteristics other than those outlined in the DSM could predict PTSD symptoms. Conclusions: DSM-5 has corrected several major ambiguities and errors of the former editions that are fundamental to the construct of PTSD as a disorder that is defined conditionally in relation. The current study is the first to examine whether DSM-5-defined traumas were associated with higher levels of PTSD than DSM-IV-defined traumas. Objective: A recent meta-analysis found that DSM-III- and DSM-IV-defined traumas were associated with only slightly higher posttraumatic stress disorder (PTSD) symptoms than nontraumatic stressors. DSM-5 expanded the diagnostic criteria for PTSD to four clusters with 20 symptoms, creating what statisticians have wryly observed are ‘636 120 ways to have posttraumatic stress disorder’ (Galatzer-Levy Reference Galatzer-Levy and Bryant 2013). ![]()
