AtypAN's relegation to a diagnosis in the \u201cother specified feeding and eating disorder\u201d (OSFED) category and paucity of research surrounding atypAN invariably implies a less clinically severe ED. However, a growing body of research has begun to question the assumption that atypAN is less severe than AN. The current review and meta\u2010analysis aimed to provide a comprehensive review to compare atypAN and AN on measures of eating disorder psychopathology, impairment, and symptom frequency to test whether atypAN is truly less clinically severe than AN.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Twenty articles that reported on atypAN and AN for at least one of the variables of interest were retrieved from PsycInfo, PubMed, and ProQuest.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>For eating\u2010disorder psychopathology, results indicated that differences were nonsignificant for most indicators; however, atypAN was associated with significantly <jats:italic>higher<\/jats:italic> shape concern, weight concern, drive for thinness, body dissatisfaction, and overall eating\u2010disorder psychopathology than AN.
