Objective Eating disorder diagnostic criteria were revised from the fourth to the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM‐IV and −5, respectively). This study examines the impact of these revisions on rates of eating disorder diagnoses in treatment‐seeking youth. Method Participants were 651 youth, ages 7–18 years, presenting to an outpatient eating disorders program who met criteria for a DSM‐IV eating disorder diagnosis on intake. Patients completed well‐validated semi‐structured interviews to assess eating disorder psychopathology and psychiatric comorbidity. Results Participants were predominantly female ( n = 588; 90.3%) with an average age of 15.28 years (SD = 2.21), mean percent of median Body Mass Index (mBMI) of 101.91 (SD = 31.73), and average duration of illness of 16.74 months (SD = 17.63). Cases of DSM‐IV Eating Disorder Not Otherwise Specified (EDNOS), now most consistent with DSM‐5 Other Specified Feeding or Eating Disorder, decreased from 47.6% to 39.0%, Anorexia Nervosa increased from 29.6% to 33.5%, and Bulimia Nervosa increased from 22.7% to 24.7%. Discussion Consistent with previous studies, and in keeping with the aims of the DSM‐5 for eating disorders, the revised diagnostic criteria reduced cases of DSM‐IV EDNOS and increased cases of specified eating disorders. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2017; 50:578–581)
