All DSM-5-TR eating disorder diagnoses will be reviewed, in addition to providing commentary as to how to assess the eating disorder diagnostic criteria. Several changes from the DSM-5 to the DSM-5-TR will be highlighted. Clinical examples will be provided to compare and contrast the different eating disorders. The diagnostic validity of the eating disorders section of the DSM-5-TR also will be discussed, particularly issues of diagnostic cross-over and diagnostic stability. Lastly, some clinical and research information in the areas of epidemiology and comorbidity will be infused throughout the presentation in order to put the diagnostic information into context.
