Nielssen and Large summarize the conclusion of our study by saying that we found criterion A2 in the DSM-IV diagnosis of Post-Traumatic Stress disorder (PTSD) (that the person’s response involves intense fear, helplessness, or horror) to be “largely redundant.” Our position was more subtle: that A2 is better conceptualized as an early predictor of PTSD than as a component of the Diagnosis.
