This study tests a mediational model of disordered eating derived from objectification theory (Fredrickson & Roberts, 1997). The model proposes that the emotion of body shame mediates the relationship between self-objectification and disordered eating. Two samples of undergraduate women (n= 93, n= 111) completed self-report questionnaires assessing self-objectification, body shame, anorexic and bulimic symptoms, and dietary restraint. Findings in both samples supported the mediational model. Additionally, a direct relationship between self-objectification and disordered eating was also observed. Implications and future research directions are discussed.
