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.
