Critical appraisal of the provisional DSM-5 criteria for anorexia nervosa and an alternative proposal.

DSM-V will be highly influential in shaping conceptions and perceptions of eating disorders by the lay public, patients, and health care providers over the next 10-15 years. DSM not only influences how medical and mental health care professionals diagnose and treat patients but also impacts health insurance policies, research funding, and clinical trials. Revisions to diagnostic criteria must be carefully considered, empirically based, and consistent with current thinking both within the field and across relevant fields. Resultant criteria should be descriptive and non-judgmental and based on empirical findings without recourse to assumed etiologies. In this forum, we review problems with the current DSM IV diagnostic criteria, concerns with the proposed DSM-5 diagnostic criteria, and present an alternative classification scheme for anorexia nervosa (AN), which more accurately captures the phenomenology of the disorder and is congruent in terminology with other fields of biomedicine.
