Abstract Objective: Revised Eating Disorder (ED) diagnostic criteria have been proposed for the Diagnostic and Statistical Manual (DSM)‐5 to reduce the preponderance of eating disorder not otherwise specified (EDNOS) and increase the validity of diagnostic groups. This article compares DSM‐IV and proposed DSM‐5 diagnostic criteria on number of EDNOS cases and validity. Method: Participants ( N = 397; 91% female) completed structured clinical interviews in a two‐stage epidemiological study of EDs. Interviewers did not follow standard skip rules, making it possible to evaluate alternative ED diagnostic criteria. Results: Using DSM‐IV versus DSM‐5 criteria, 34 (14%) versus 48 (20%) had anorexia nervosa, 43 (18%) versus 44 (18%) had bulimia nervosa, and 163 (68%) had EDNOS versus 20 (8%) had binge eating disorder (BED), and 128 (53%) had EDNOS, respectively, reflecting a significant decrease in EDNOS. Validation analyses supported significant differences among groups with some improvement associated with delineation of BED. Discussion: Proposed revisions to EDs in the DSM‐5 significantly reduced reliance on EDNOS without loss of information. © 2011 by Wiley Periodicals, Inc.
