RESUMO
A randomized controlled trial was conducted to assess the efficacy of the Body Project eating disorder prevention program in reducing eating disorder risk factors and symptoms in young Brazilian women. A total of 141 female university students aged 18-30 years old were randomly assigned to one of two conditions: assessment-only condition (n = 78) and Body Project condition (n = 63). Participants completed scales assessing body dissatisfaction, sociocultural influence, disordered eating attitudes and behaviors, eating disorders symptoms, body appreciation, depressive mood and negative affect at baseline, posttest, and at 1- and 6-month follow-ups. Body Project participants showed significantly greater reductions in body dissatisfaction, sociocultural influence, disordered eating, eating disorder symptoms, depressive symptoms, and negative affect, and greater increases in body appreciation (d = .35-.48) compared to assessment-only participants. Most of the effects persisted through 6-month follow-up (d = .35-.74). Results provide evidence that the Body Project is an effective intervention to reduce eating disorder risk factors and eating disorder symptoms among Brazilian young women, and that this intervention is naturally culturally adaptive.

BACKGROUND: Given that most young women with eating disorders do not receive treatment, implementing effective prevention programs is a public health priority. The Body Project is a group-based eating disorder prevention program with evidence of both efficacy and effectiveness. This trial evaluated the efficacy of this prevention program with Brazilian girls, as no published study has tested whether this intervention is culturally sensitive and efficacious with Latin-American adolescents. METHODS: Female students were allocated to a dissonance-based intervention (n = 40) or assessment-only (n = 22) condition. The intervention was a dissonance-based program, consisted of four group sessions aimed to reduce thin-ideal internalization. The sessions included verbal, written, and behavioral exercises. The intervention group was evaluated at pretest and posttest; assessment-only controls completed measures at parallel times. RESULTS: Compared to assessment-only controls, intervention participants showed a significantly greater reduction in body dissatisfaction, sociocultural influence of the media, depressive symptoms, negative affect, as well as significantly greater increases in body appreciation. There were no significant effects for disordered eating attitudes and eating disorder symptoms. CONCLUSIONS: These results suggest that this dissonance-based eating disorder prevention program was culturally sensitive, or at least culturally adaptive, and efficacious with Brazilian female adolescents. Indeed, the average effect size was slightly larger than has been observed in the large efficacy trial of this prevention program and in recent meta-analytic reviews. TRIAL REGISTRATION: RBR-7prdf2 . Registered 13 August 2018 (retrospectively registered).

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.
