title = "Radcliffe ARFID Workgroup: Toward operationalization of research diagnostic criteria and directions for the field",
abstract = "Objective: Since its introduction to the psychiatric nomenclature in 2013, research on avoidant/restrictive food intake disorder (ARFID) has proliferated highlighting lack of clarity in how ARFID is defined. Method: In September 2018, a small multi-disciplinary pool of international experts in feeding disorder and eating disorder clinical practice and research convened as the Radcliffe ARFID workgroup to consider operationalization of DSM-5 ARFID diagnostic criteria to guide research in this disorder. Results: By consensus of the Radcliffe ARFID workgroup, ARFID eating is characterized by food avoidance and/or restriction, involving limited volume and/or variety associated with one or more of the following: weight loss or faltering growth (e.g., defined as in anorexia nervosa, or by crossing weight/growth percentiles); nutritional deficiencies (defined by laboratory assay or dietary recall); dependence on tube feeding or nutritional supplements (≥50% of daily caloric intake or any tube feeding not required by a concurrent medical condition); and/or psychosocial impairment. Conclusions: This article offers definitions on how best to operationalize ARFID criteria and assessment thereof to be tested in existing clinical populations and to guide future study to advance understanding and treatment of this heterogeneous disorder.",

This meeting was supported by the Radcliffe Institute Exploratory Seminar Program (Radcliffe Institute for Advanced Study, Harvard University,), which exists to promote intellectual risk-taking in new areas of scholarship (see https://www.radcliffe.harvard.edu/academic-ventures/seminars-workshops/exploratory-seminars for more information about program and guidelines). Our cohort included clinical psychologists, psychiatrists, pediatricians (including adolescent medicine specialists), dietitians, a gastroenterologist, an endocrinologist, a speech and language pathologist, and an occupational therapist who work at all levels of care and with patients of all ages. Invitees were a limited pool of experts in the field: researchers actively publishing ARFID findings or clinicians with active ARFID practices who were selected to represent multiple disciplines and a range of career stages from junior to senior investigators and clinicians. Due to budgetary constraints there was a larger representation from the Boston area, which was the location of the seminar; however, we made efforts to achieve geographical diversity and 20% of our attendees came from outside of the United States. Our objective was to consider operationalization of the ARFID diagnostic criteria and assessment thereof for research purposes and reach consensus through multi-disciplinary discussion whenever possible. We share the summary of this meeting to highlight discussion-based consensus operationalizations (i.e., agreed upon by the majority of attendees) and suggest key future directions to advance study of this heterogeneous disorder.
