This meta-analysis of eating disorder prevention programs found that intervention effects ranged from an absence of any effects to reductions in current and future eating pathology. Certain effects persisted as long as 2 years and were superior to minimal-intervention control conditions. Larger effects occurred for selected (vs. universal), interactive (vs. didactic), and multisession (vs. single session) programs; for programs offered solely to females and to participants over age 15; for programs without psychoeducational content; and for trials that used validated measures. The results identify promising prevention programs and delineate sample, format, and design features that are associated with larger effects, but they suggest the need for improved methodological rigor and statistical modeling of trials and enhanced theoretical rationale for interventions.
这项针对饮食失调预防项目的荟萃分析发现，干预效果从没有任何效果到减少当前和未来的饮食病理学症状不等。某些效果可持续长达2年，且优于最低干预控制条件。对于选定的（相对于普遍的）、互动式的（相对于说教式的）和多节次的（相对于单节次的）项目；对于仅针对女性和15岁以上参与者的项目；对于没有心理教育内容的项目；以及对于使用经过验证的测量方法的试验，效果更为显著。研究结果确定了有前景的预防项目，并勾勒出与更大效果相关的样本、形式和设计特征，但也表明需要提高试验的方法严谨性和统计建模，并加强干预的理论依据。
