title: Broad categories for the diagnosis of eating disorders (BCD-ED): an alternative system for classification.
abstract: OBJECTIVE
  Eating Disorder Not Otherwise Specified (EDNOS), a residual category in DSM-IV, is the most commonly used eating disorder diagnosis in clinical settings. A diagnostic scheme, termed Broad Categories for the Diagnosis of Eating Disorders (BCD-ED), is proposed to diminish use of the EDNOS category while preserving the existing eating disorder categories. The objective of this review was to examine the advantages and disadvantages of adopting this scheme for DSM-V.
  
  
  METHODS
  We reviewed published studies to assess the proportion of individuals with DSM-IV EDNOS that would be reclassified under the BCD-ED system, support for the hierarchy of the three categories, and the potential risk of "overdiagnosis."
  
  
  RESULTS
  Adopting the BCD-ED scheme would have both advantages and disadvantages, but would likely substantially reduce the number of individuals who would receive an EDNOS diagnosis.
  
  
  CONCLUSIONS
  BCD-ED is a potential method of addressing the high frequency of EDNOS, but would be a major change in how eating disorders are categorized.
