A Phase II trial from Washington University School of Medicine is recruiting 800 adults to optimise an automated chatbot intervention for clinical and subclinical eating disorders. The study targets the large population of individuals with eating disorders who are not currently receiving treatment, using the validated EDE-Q as its primary outcome measure. Results are anticipated to inform scalable, technology-driven approaches to closing the persistent eating disorder treatment gap.
