Dsm-5 and icd-11 definitions of posttraumatic stress disorder: investigating “narrow” and “broad” approaches

2022National Library of Medicine

A total of 5.6% of respondents met criteria for “broadly defined” PTSD (i.e., full criteria in at least one diagnostic system), with prevalence ranging from 3.0% with DSM-5 to 4.4% with ICD-10. Only one-third of broadly defined cases met criteria in all four systems and another one third in only one system (narrowly defined cases). Between-system differences in indicators of clinical severity suggest that ICD-10 criteria are least strict and DSM-IV criteria most strict. The more striking result, though, is that significantly elevated indicators of clinical significance were found even for narrowly defined cases for each of the four diagnostic systems.
