Eating Disorder Prevention in Sororities: Testing Mediators ofIntervention Effects Público

Abstract

Abstract Eating Disorder Prevention in Sororities: Testing Mediators of Intervention Effects By Lisa M. Smith This study evaluated mechanisms through which intervention effects were achieved in a cognitive dissonance-based program (CD) that significantly reduced eating disorder risk factors among sorority women. CD is hypothesized to reduce body dissatisfaction, and thus risk for disordered eating. More importantly CD is hypothesized to reduce body dissatisfaction primarily through reducing the degree of thin-ideal internalization (Becker, Smith & Ciao, 2005). Thus, the current study evaluated the degree to which thin-ideal internalization and body dissatisfaction each serve as specific mechanisms of change within CD. CD produced significant reductions in the outcome measures (dietary restraint and eating disorder pathology) and in reductions in both of the mediators (thin- ideal internalization and body dissatisfaction). Our results provide some support for partial and complete mediation in outcome measures during intervention and in change sustained from pre-intervention to one-month follow-up. Our data suggest, however, that ultimately reduced body dissatisfaction is the primary mediator of sustained reductions in eating disordered behaviors.
