Establishing consensus for labeling and defining the later stage of anorexia nervosa: A Delphi study.

Varied perspectives on the later stage of anorexia nervosa (AN) have left the field of eating disorders without a consistent label or definition for this subpopulation. As a result, diverse criteria when recruiting participants have led to incomparable results across research studies and a lack of guidance when assessing and treating patients in the clinical context. The aim of the current study was to develop consensus-based guidelines on the labeling and defining of the later stage of AN.
