Emerging evidence suggests that interventions designed to target and isolate one key change mechanism may also produce meaningful change in core symptoms. Although both \u2018broad\u2019 and \u2018focused\u2019 digital programs have demonstrated efficacy, no study has performed a direct, head-to-head comparison of the two approaches. We addressed this through a randomized non-inferiority trial.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291722001477_sec_a2\" sec-type=\"methods\"><jats:title>Method<\/jats:title><jats:p>Participants with recurrent binge eating were randomly assigned to a broad (<jats:italic>n<\/jats:italic> = 199) or focused digital intervention (<jats:italic>n<\/jats:italic> = 199), or a waitlist (<jats:italic>n<\/jats:italic> = 202). The broad program targeted dietary restraint, mood intolerance, and body image disturbances, while the focused program exclusively targeted dietary restraint. Primary outcomes were eating disorder psychopathology and binge eating frequency.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291722001477_sec_a3\" sec-type=\"results\"><jats:title>Results<\/jats:title><jats:p>In intention-to-treat analyses, both intervention groups reported greater improvements in primary and secondary outcomes than the waitlist, which were sustained at an 8-week follow-up.
