Efficacy trials indicate that an eating disorder prevention program involving dissonance-inducing activities that decrease thin-ideal internalization reduces risk for current and future eating pathology, yet it is unclear whether this program produces effects under real-world conditions. The present effectiveness trial tested whether this program produced effects when school staff recruit participants and deliver the intervention. Adolescent girls with body image concerns (N = 306; M age = 15.7, SD = 1.1) randomized to the dissonance intervention showed significantly greater decreases in thin-ideal internalization, body dissatisfaction, dieting attempts, and eating disorder symptoms from pretest to posttest than did those assigned to a psychoeducational brochure control condition, with the effects for body dissatisfaction, dieting, and eating disorder symptoms persisting through 1-year follow-up. Effects were slightly smaller than those observed in a prior efficacy trial, suggesting that this program is effective under real-world conditions, but that facilitator selection, training, and supervision could be improved.
功效试验表明，一项涉及引发认知失调活动的饮食失调预防计划，能够减少对瘦理想形象的内化，降低当前和未来出现饮食问题的风险，但尚不清楚该计划在现实世界条件下是否会产生效果。本次有效性试验检验了在学校工作人员招募参与者并实施干预的情况下，该计划是否会产生效果。与被分配到心理教育手册对照条件的女孩相比，随机分配到认知失调干预组的有身体形象担忧的青春期女孩（N = 306；平均年龄 = 15.7，标准差 = 1.1），从预测试到后测试，在瘦理想形象内化、身体不满、节食尝试和饮食失调症状方面的减少幅度显著更大，身体不满、节食和饮食失调症状的影响持续到1年随访期。这些效果略小于先前功效试验中观察到的效果，表明该计划在现实世界条件下是有效的，但促进者的选择、培训和监督可以改进。
