Analyses of thin-ideal internalization and self-objectification were conducted within the context of a cognitive dissonance based eating disorder prevention program implemented in an undergraduate sorority. Participants completed self-report assessments at baseline (n=177), post-intervention (n=169), 5-month (n=159), and 1-year follow-up (n=105). Cross-sectional path analysis indicated that thin-ideal internalization and self-objectification predict each other and both predict body dissatisfaction, which in turn, predicts eating disorder symptoms. A longitudinal examination conducted using hierarchical linear modeling indicated that participants showed significant reductions in thin-ideal internalization, self-objectification, body dissatisfaction, and eating disorder symptoms after participating in the prevention program. Reductions of symptoms were maintained 1-year post-intervention, with the exception of self-objectification, which was significantly reduced up to 5-months post-intervention. Collectively, results suggest that targeting both thin-ideal internalization and self-objectification simultaneously within eating disorder prevention programs could increase the reduction of eating disorder symptoms.
