Classification of eating disorders: comparison of relative prevalence rates using DSM-IV and DSM-5 criteria

DSM-5 contains substantial changes to eating disorder diagnoses. We examined relative prevalence rates of DSM-IV and DSM-5 eating disorder diagnoses using Eating Disorder Examination-Questionnaire diagnostic algorithms in 117 community out-patients. DSM-5 criteria produced a reduction in combined `other specified feeding or eating disorder? and `unspecified feeding or eating disorder? diagnoses from 46 to 29 , an increase in anorexia nervosa diagnoses from 35 to 47 , the same number of bulimia nervosa diagnoses and a 5 rate of binge eating disorder diagnoses.
