A Test and Extension of Objectification Theory as It Predicts Disordered Eating: Does Women's Age Matter?.
When predicting disordered eating, models incorporating several of objectification theory’s (B. L. Fredrickson & T. A. Roberts, 1997) core constructs (i.e., sexual objectification, self-objectification, body shame, poor interoceptive awareness) have been empirically supported with women of traditional undergraduate age who are consistent in age with the youthful-ideal prototype for women presented in the media. The present study extended this research by testing these core constructs with women ages 25–68 years (n 330), as their experiences with these constructs may differ as they deviate from this youthful prototype. A multiple-groups analysis comparing these women with women ages 18–24 (n 329) indicated that objectification theory can be extended to women ages 25 and older, as the model provided an adequate fit to the data. However, structural invariance analysis revealed that what takes place within the model may not be identical for these groups. The older group had a stronger relationship between body shame and disordered eating and a weaker relationship between poor interoceptive awareness and disordered eating than did the younger group.
