RecruitingBehavioural interventionOpen vs. Blind Weighing Study In Adolescents and Young Adult With Eating DisordersCurrent treatments for adolescents and young adults (AYAs) with eating disorders (EDs) do not effectively address a central ED symptom - anxiety about weight gain - which contributes to poor outcomes. The proposed study evaluates the feasibility, acceptability, efficacy, and underlying mechanisms of an enhanced version of "open weighing," a cognitive-behavioral intervention designed to target anxiety about weight gain in AYAs with EDs. Understanding how to better treat AYAs with EDs, and identifying the mechanisms by which interventions lead to improvement, will aid in the development of more effective and personalized treatments, ultimately improving the lives of AYAs with EDs.
