This study sought to evaluate the degree to which positive effects remained when a well studied cognitive dissonance eating disorder prevention program was disseminated through a large national sorority under naturalistic conditions. All participants underwent a 2-session program run by peer facilitators. The sample included 182 undergraduate women from a local chapter of a national sorority at a large public university. Analyses revealed that the program significantly reduced body dissatisfaction, thin ideal internalization, dietary restraint, and the use of the media as a source of information about beauty, and restrained eating. Importantly, effect sizes were maintained at 5-months and 1-year follow-up. These findings demonstrate that empirically supported programs can remain effective when disseminated with careful training in large social systems.
