This pilot study investigated the effectiveness of a social media literacy intervention for adolescent girls on risk factors for eating disorders.
A quasi-experimental pre- to post-test design comparing intervention and control conditions was used. Participants were 101 adolescent girls (M = 13.13, SD = 0.33) who were allocated to receive three social media literacy intervention lessons (n = 64) or to receive classes as usual (n = 37). Self-report assessments of eating disorder risk factors were completed one week prior to, and one week following the intervention.
Significant group by time interaction effects revealed improvements in the intervention condition relative to the control condition for body image (body esteem-weight; d = .19), disordered eating (dietary restraint; d = .26) and media literacy (realism scepticism; d = .32).
The outcomes of this pilot study suggest that social media literacy is a potentially useful approach for prevention of risk for eating disorders in adolescent girls in the current social media environment of heightened vulnerability. Replication of this research with larger, randomized controlled trials, and longer follow-up is needed.
本试点研究调查了针对青春期女孩的社交媒体素养干预对饮食失调风险因素的有效性。
采用了一种准实验性的前测-后测设计，比较干预组和对照组的情况。参与者为101名青春期女孩（M = 13.13，标准差 = 0.33），她们被分配接受三节社交媒体素养干预课程（n = 64）或照常上课（n = 37）。在干预前一周和干预后一周完成了饮食失调风险因素的自我报告评估。
显著的组间时间交互效应显示，与对照组相比，干预组在身体形象（身体自尊-体重；d = 0.19）、饮食失调（饮食限制；d = 0.26）和媒体素养（现实主义怀疑论；d = 0.32）方面有所改善。
本试点研究的结果表明，在当前脆弱性增加的社交媒体环境中，社交媒体素养是预防青春期女孩饮食失调风险的一种潜在有用方法。需要通过更大规模的随机对照试验和更长时间的随访来重复这项研究。
