功效试验表明，包括减少瘦-理想内化的不和谐诱导活动的饮食障碍预防计划可以降低当前和未来饮食病理的风险，但尚不清楚该计划是否在现实世界条件下产生效果。目前的有效性试验测试了当学校工作人员招募参与者并提供干预时，该计划是否产生了效果。有身体形象问题的青春期女孩(N=306；女性年龄=15.7，SD=1.1)被随机分配到不和谐干预组，从测试前到测试后，瘦理想内化、身体不满、节食尝试和进食障碍症状的下降幅度显著高于那些被分配到心理教育手册对照条件的女孩，对身体不满、节食和进食障碍症状的影响持续到一年的随访。效果比先前的疗效试验中观察到的略小，这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。
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 I-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.
