This study compared the efficacy of a media literacy program and a self-esteem program designed to reduce general and specific risk factors for eating disorders.
Four classes of 86 grade 8 students (53 boys and 33 girls), mean age of 13 years, were randomly assigned to either a control condition or one of the two intervention conditions. Assessment of general and specific risk factors was carried out at baseline, postintervention and 3-month follow-up.
At postintervention the media literacy group had lower mean scores on weight concern than the control group (p =0.007) but the self-esteem group did not. There were some differences on self-esteem measures at the 3-month follow-up.
Media literacy programs combined with an interactive, student-centered framework may potentially be a safe and effective way of reducing risk factors for eating disorders. The impact of teaching style needs to be further evaluated in prevention research.
本研究比较了旨在降低饮食失调的一般和特定风险因素的媒体素养计划和自尊计划的效果。
将四个班级的86名八年级学生（53名男生和33名女生），平均年龄13岁，随机分配到一个对照条件或两个干预条件之一。在基线、干预后和3个月随访时对一般和特定风险因素进行评估。
干预后，媒体素养组在体重关注方面的平均得分低于对照组（p = 0.007），但自尊组没有。在3个月随访时，自尊测量方面存在一些差异。
结合互动式、以学生为中心框架的媒体素养计划可能是降低饮食失调风险因素的一种安全有效的方法。教学风格的影响需要在预防研究中进一步评估。
