“…The majority of publications comparing DSM-IV to DSM-5 report no differences (Carmassi et al, 2013; Elhai, Ford, Ruggiero, & Christopher Frueh, 2009; Elhai et al, 2012; Gentes et al, 2014; Kilpatrick et al, 2013; Miller et al, 2013; O’Donnell et al, 2014), with the exception of Forbes et al (2011) who found lower PTSD prevalence under DSM-5. Of those who reported consistency (Carmassi et al, 2013; Elhai et al, 2009; Gentes et al, 2014; Kilpatrick et al, 2013), all reported satisfying high agreement between both versions of the DSM. Comparing the proposed ICD-11 to DSM-IV criteria, Stammel, Abbing, Heeke, and Knaevelsrud (2015) reported reduced PTSD prevalence according to the proposed ICD-11 criteria.…”
