Objective: This study explored the effects of participating in a dissonance-based eating disorder prevention program on changes in thin ideal internalization, body dissatisfaction, and eating symptoms among White, Asian American, and Hispanic participants.
Method: Participants were (n = 394), 13 to 20-year-old adolescent girls and young women who reported being White (n = 311), Hispanic/Latina (n = 61), or Asian-American/Hawaiian/Pacific Islander (n = 33). The current study used data drawn from the pre- and post assessments of an efficacy trial and an effectiveness trial of this eating disorder prevention program.
Results: The intervention reduced disordered eating behaviors and eating disorder risk factors for all three ethnic groups at post-intervention assessment; there was no evidence of significantly stronger effects in any particular ethnic group.
Conclusion: Results suggest that a cognitive dissonance-based prevention program for eating disorders may be equally effective for Asian American, Hispanic, and White adolescent women.
