The degree to which media contributes to body dissatisfaction, life satisfaction and eating disorder symptoms in teenage girls continues to be debated. The current study examines television, social media and peer competition influences on body dissatisfaction, eating disorder symptoms and life satisfaction in a sample of 237 mostly Hispanic girls. 101 of these girls were reassessed in a later 6-month follow-up. Neither television exposure to thin ideal media nor social media predicted negative outcomes either concurrently nor prospectively with the exception of a small concurrent correlation between social media use and life satisfaction. Social media use was found to contribute to later peer competition in prospective analysis, however, suggesting potential indirect but not direct effects on body related outcomes. Peer competition proved to be a moderate strong predictor of negative outcomes both concurrently and prospectively. It is concluded that the negative influences of social comparison are focused on peers rather than television or social media exposure.
媒体对少女的身体不满、生活满意度和饮食失调症状的影响程度仍存在争议。本研究以 237 名主要为西班牙裔的少女为样本，考察了电视、社交媒体和同伴竞争对身体不满、饮食失调症状和生活满意度的影响。其中 101 名少女在 6 个月后的后续随访中再次接受评估。除了社交媒体使用与生活满意度之间存在小的同期相关性外，电视接触瘦理想媒体或社交媒体使用既不能预测同期也不能预测前瞻性的负面结果。然而，在前瞻性分析中发现，社交媒体的使用导致了后来的同伴竞争，这表明社交媒体对与身体相关的结果有潜在的间接影响，但没有直接影响。同伴竞争被证明是同期和前瞻性负面结果的中度强预测因素。研究结论是，社会比较的负面影响集中在同伴身上，而不是电视或社交媒体的暴露。
