Behavioral Health and Interventions

Research supports the efficacy of both cognitive dissonance (CD) and healthy weight (HW) eating disorders prevention, and indicates that CD can be delivered by peer-facilitators, which facilitates dissemination. This study investigated if peer-facilitators can deliver HW when it is modified for their use and extended follow-up of peer-facilitated CD as compared to previous trials. Based on pilot data, we modified HW (MHW) to facilitate peer delivery, elaborate benefits of the healthy-ideal, and place greater emphasis on consuming nutrient dense foods. Female sorority members (N = 106) were randomized to either two 2-h sessions of CD or MHW. Participants completed assessment pre- and post-intervention, and at 8-week, 8-month, and 14-month follow-up. Consistent with hypotheses, CD decreased negative affect, thin-ideal internalization, and bulimic pathology to a greater degree post-intervention. Both CD and MHW reduced negative affect, internalization, body dissatisfaction, dietary restraint, and bulimic pathology at 14 months.
