Weight Stigma's Effects on Misdiagnosis of Eating Disorders Among Laypeople and Healthcare Professionals.

Objective: There is limited research on weight bias in diagnosing eating disorders (EDs), particularly among healthcare professionals (HCPs). This is especially true for atypical anorexia nervosa, a diagnosis recently described in the DSM that includes people with anorexia nervosa symptoms who are not clinically underweight.

Method: Using a within-subjects design, we assessed diagnosis, diagnostic confidence, and ED-related medical knowledge among a sample of lay people and medical professionals.
