Exposure to thin-ideal media can contribute to increased body dissatisfaction in adolescent girls. Understanding the factors that may prevent or exacerbate the negative effects of media exposure on body dissatisfaction is important to facilitate prevention of these problems. This study evaluated the effects of exposure to thin-ideal media images on body image in three instructional set experimental conditions: appearance comparison, peer norms, and control. An important aim was to examine baseline levels of media literacy as a protective factor and trait thin-ideal internalization and trait upward appearance comparison as risk factors. Early adolescent girls (N = 246) completed baseline measures and 1 week later viewed thin-ideal media images, before and after which they rated their state body satisfaction. Participants in the appearance comparison instruction but not peer norms instruction condition had significantly reduced body satisfaction. Media literacy, particularly high levels of critical thinking, mitigated the negative effects of trait thin-ideal internalization and trait upward appearance comparison on body satisfaction outcomes. These findings provide evidence for the role of media literacy as a protective factor against the negative effects on body satisfaction of exposure to thin-ideal media images, and also provide evidence to support the development and implementation of media literacy-based body image interventions.
暴露于理想化的身材媒体可能会导致少女的身体不满感增加。了解可能预防或加剧媒体暴露对身体不满感的负面影响的因素对于促进这些问题的预防很重要。本研究在三种教学设定实验条件下评估了暴露于理想化身材媒体图像对身体形象的影响:外貌比较、同辈规范和控制。一个重要目标是检验媒体素养作为保护因素的基线水平,以及特质理想化内化和特质向上外貌比较作为风险因素。青春期早期女孩(N=246)完成了基线测量,一周后观看了理想化身材的媒体图像,在此之前和之后,她们对自己的状态身体满意度进行了评价。在外观比较指导但不在同辈规范指导条件下的参与者的身体满意度显著降低。媒体素养,特别是批判性思维的高水平,减轻了特质理想化内化和特质向上外貌比较对身体满意度结果的负面影响。这些发现为媒体素养作为预防身体满意度因暴露于理想化身材媒体图像而受到负面影响的保护因素的作用提供了证据,也为支持基于媒体素养的身体形象干预的制定和实施提供了证据。
