A disadvantage of DSM-IV's broad EDNOS category was that people with very different symptoms were still classified as having the same diagnosis, making it difficult to access care specific to the disorder and conduct research on the diversity of pathology within EDNOS.[14] Furthermore, EDNOS was perceived as less severe than AN or BN, despite findings that individuals diagnosed with EDNOS share similarities with full-threshold AN or BN in the degree of eating pathology, general psychopathology, and physical health.[15] This perception prevented people in need from seeking help or insurance companies from covering treatment costs.[15] DSM-5, published in 2013, sought to address these issues by adding new diagnoses and revising existing criteria.
