Of the 12.2% of cases positive for DSM-5, but not DSM-IV criteria, none resulted from failure to meet Criterion A1, but 2% were due to not meeting Criterion A2 of the DSM-IV. Most cases meeting the DSM-5, but not the DSM-IV criteria were due to either not meeting the DSM-IV Criterion C (avoidance/numbing) or Criterion D (arousal). Specifically, 55% did not meet the DSM-IV Criterion C, 38% did not meet the DSM-IV Criterion D, and 5% met neither the DSM-IV C nor D criteria.
