General and program-specific moderators of two eating disorder prevention programs

Authors


Abstract

Objective:

To investigate general and program-specific factors hypothesized to moderate the effects of two eating disorder prevention programs.

Method:

High-risk adolescent girls (N = 481; M age = 17) were randomized to a dissonance-based thin-ideal internalization reduction program, a healthy weight management program, an expressive-writing control condition, or an assessment-only control condition. Participants completed diagnostic interviews and surveys at pretest, post-test, 6-month follow-up, and 12-month follow-up.

Results:

Dissonance program effects on bulimic symptoms were stronger for participants with initial elevations in body image distress, bulimic symptoms, and thin-ideal internalization. Healthy weight program effects on bulimic symptoms were stronger for adolescents with initial elevations in body image distress, bulimic symptoms, readiness to change, body mass, and emotional eating.

Conclusion:

Overall, intervention effects tended to be amplified for high-risk versus low-risk adolescents. However, certain moderator effects appeared to be specific to the two different prevention programs. © 2008 by Wiley Periodicals, Inc. Int J Eat Disord 2008
