A meta-analytic review of eating disorder prevention programs: encouraging findings.
This meta-analytic review found that 51% of eating disorder prevention programs reduced eating disorder risk factors and 29% reduced current or future eating pathology. Larger effects occurred for programs that were selected (versus universal), interactive (versus didactic), multisession (versus single session), solely offered to females (versus both sexes), offered to participants over 15 years of age (versus younger ones), and delivered by professional interventionists (versus endogenous providers). Programs with body acceptance and dissonance-induction content and without psychoeducational content and programs evaluated in trials using validated measures and a shorter follow-up period also produced larger effects. Results identify promising programs and delineate sample, format, and design features associated with larger effects, which may inform the design of more effective prevention programs in the future.
