In their letter to the editor, Brodrick and McAdams ( 1 Brodrick B. McAdams C. Insight may limit identification of eating disorders. Biol Psychiatry. 2019; 85: e55-e56 Scopus (4) Google Scholar ) raised two measurement-related concerns regarding our previous report ( 2 Udo T. Grilo C.M. Prevalence and correlates of DSM-5–defined eating disorders in a nationally representative sample of U.S. adults. Biol Psychiatry. 2018; 84: 345-354 Abstract Full Text Full Text PDF PubMed Scopus (357) Google Scholar ) on the prevalence and correlates of eating disorders (EDs) based on DSM-5 criteria using data from the 2012 to 2013 National Epidemiological Survey on Alcohol and Related Conditions-III. This DSM-5–based study ( 2 Udo T. Grilo C.M. Prevalence and correlates of DSM-5–defined eating disorders in a nationally representative sample of U.S. adults. Biol Psychiatry. 2018; 84: 345-354 Abstract Full Text Full Text PDF PubMed Scopus (357) Google Scholar ) reported lower prevalence estimates for both bulimia nervosa and binge-eating disorder and a lower persistence rate for anorexia nervosa (AN) than expected based on previous DSM-IV studies ( 1 Brodrick B. McAdams C. Insight may limit identification of eating disorders. Biol Psychiatry. 2019; 85: e55-e56 Scopus (4) Google Scholar , 3 Hudson J.I. Pope H.G.

Prevalence and correlates of DSM-5–defined eating disorders in a nationally representative sample of U.S. adults. Biol Psychiatry. 2018; 84: 345-354 Abstract Full Text Full Text PDF PubMed Scopus (357) Google Scholar ) and a commentary by Hudson and Pope ( 3 Hudson J.I. Pope H.G. Evolving perspectives on the public health burden of eating disorders. Biol Psychiatry. 2018; 84: 318-319 Abstract Full Text Full Text PDF PubMed Scopus (9) Google Scholar ) highlighted these discrepancies with the only other nationally representative U.S. survey—the 2001 to 2003 National Comorbidity Survey Replication ( 4 Hudson J.I. Hiripi E. Pope Jr., H.G. Kessler R.C. The prevalence and correlates of eating disorders in the National Comorbidity Survey Replication. Biol Psychiatry. 2007; 61: 348-358 Abstract Full Text Full Text PDF PubMed Scopus (3368) Google Scholar )—and the World Health Organization Survey ( 5 Kessler R.C. Berglund P.A. Chiu W.T. Deitz A.C. Hudson J.I. Shahly V. et al. The prevalence and correlates of binge eating disorder in the World Health Organization World Mental Health Surveys. Biol Psychiatry. 2013; 73: 904-914 Abstract Full Text Full Text PDF PubMed Scopus (763) Google Scholar ), and discussed possible contributors to variations in prevalence estimates across studies (e.g., changes in diagnostic criteria, different interviews and interview structures such as length and ordering, fatigue, administration training methods, sampling, different date cohorts). Importantly, neither our ( 2 Udo T. Grilo C.M. Prevalence and correlates of DSM-5–defined eating disorders in a nationally representative sample of U.S. adults. Biol Psychiatry. 2018; 84: 345-354 Abstract Full Text Full Text PDF PubMed Scopus (357) Google Scholar ) nor the Hudson et al. ( 4 Hudson J.I. Hiripi E. Pope Jr., H.G. Kessler R.C. The prevalence and correlates of eating disorders in the National Comorbidity Survey Replication. Biol Psychiatry. 2007; 61: 348-358 Abstract Full Text Full Text PDF PubMed Scopus (3368) Google Scholar ) sensitivity analyses exploring the potential impacts of looser or stricter diagnostic definitions revealed any substantial effects on prevalence estimates.

We previously obtained the same dataset from the National Epidemiologic Survey on Alcohol and Related Conditions and became concerned about the ability of this structured phone interview (Alcohol Use Disorder and Associated Disabilities Interview Schedule-5) to assess eating disorders. These results are reported both here and previously in Afifi et al. Full-Text PDF
