As eating disorders have severe consequences, they require prevention. We aimed to compare maladaptive beliefs related to eating disorders by following two programs based on media literacy in adolescents at post-test intervention, and after 6 and 12month-follow-ups. The Male and Female Nutrition and Media Literacy Model preventive program (NUT+MEF+MEM+ML in Spanish) and the Theater Alive program are both based on the same contents, the former being presented in a multimedia and interactive format and the latter in a drama format. Both were compared to a control group without intervention, whose participants received usual classes before the assessments.
Participants were 178 adolescents in the second year of compulsory secondary education from fours schools of Terrassa (Catalonia, Spain). All participants in each school were assigned to the same group, depending on school schedules. A mixed 3 (group: Theater Alive, NUT+MEF+MEM+ML, control)×3 (time: post-test, 6-month-follow-up, 12-month-follow-up) factorial design was used to evaluate the effect on maladaptive beliefs measured using a CE-TCA tool.
When compared to the control group, both Theater Alive (d=0.88) and NUT+MEM+MEF+ML (d=0.60) obtained lower scores over time, the latter being not statistically significant.
The Theater Alive program may produce an effect of cognitive dissonance that might eliminate the discrepancy between the contents of the play and those that are internalized, thus modifying maladaptive beliefs. Participants in the Theater Alive program, as actors in front of an audience, had to defend certain content that was rehearsed over and over again to the point until it became internalized.
由于饮食失调会产生严重后果，因此需要进行预防。我们旨在通过在测试后干预时以及在6个月和12个月随访后，对基于媒体素养的两个项目进行跟踪，比较青少年中与饮食失调相关的适应不良信念。男性和女性营养与媒体素养模型预防项目（西班牙语为NUT+MEF+MEM+ML）和“活剧”项目均基于相同的内容，前者以多媒体和互动形式呈现，后者以戏剧形式呈现。将这两个项目与未进行干预的对照组进行比较，对照组的参与者在评估前接受常规课程。
参与者是来自西班牙加泰罗尼亚省特拉萨市四所学校的178名义务中等教育二年级青少年。根据学校日程安排，每所学校的所有参与者都被分配到同一组。采用混合的3（组：“活剧”、NUT+MEF+MEM+ML、对照组）×3（时间：测试后、6个月随访、12个月随访）析因设计，以评估使用CE-TCA工具测量的适应不良信念的影响。
与对照组相比，“活剧”组（d=0.88）和NUT+MEM+MEF+ML组（d=0.60）随着时间推移得分均较低，后者无统计学意义。
“活剧”项目可能会产生认知失调效应，这可能会消除戏剧内容与内化内容之间的差异，从而改变适应不良信念。“活剧”项目的参与者作为面对观众的演员，必须捍卫反复排练直至内化的特定内容。
