OBJECTIVE: With anorexia nervosa (AN) having various presentations, attention has been directed towards particularly durable forms of the condition in both research and clinical contexts. A major hindrance in terms of advancing the field is the inconsistent labeling and defining of this subgroup. This has two implications; first, the inconsistent recruitment of participants when researching this sample, and second, the misdiagnosing of patients who may or may not have a durable course of the disease. The current research had the purpose of providing an overview of the current labels and criteria used for defining cases of severe and enduring AN, and critically analysing the implications of these findings. METHOD: In accordance with PRISMA guidelines, a literature search was conducted using four electronic databases (PsycINFO, MEDLINE, Web of Science and Scopus) in order to identify 32 records that met the standards stipulated by the criteria. Data extraction included explicit labeling, the definition or criteria used to describe the subgroup, along with participant age and study design. RESULTS: It was found that the terms chronic and severe and enduring were the most commonly used adjectives when referring to this subgroup. In terms of criteria, illness duration and the number of previously failed treatment attempts were the most common defining features within the literature. DISCUSSION: It is the aim of the authors to inspire further research into what is the most appropriate label and defining features for the subgroup in order to facilitate a better approach and outcome for the individuals affected.
