 Eating disorders EDs have the highest rate of mortality of any mental illness. On U.S. college campuses, an estimated 80 students with clinically significant ED symptoms do not receive treatment. There are likely more than one million students whose EDs go untreated in any given year. Left untreated EDs typically become more severe and refractory to treatment. Given the impact of EDs on mental and physical health and the connection therein with social, academic, and economic outcomes, an effective intervention to increase rates of treatment utilization would have broad societal effects extending well beyond the campus setting. This study is an online intervention designed to identify and increase help-seeking among undergraduates with previously undiagnoseduntreated EDs.
