目的探讨青春期女孩社交媒体素养干预对进食障碍危险因素的影响。方法采用准实验前后测设计，比较干预和控制条件。被试为101名青春期女孩(男性=13.13岁，SD=0.33岁)，她们被分配接受3堂社交媒体素养干预课(n=)或照常上课(n=37)。对饮食障碍危险因素的自我报告评估在干预前一周和干预后一周完成。结果显著的按时间分组交互效应显示，相对于身体形象(身体自尊-体重；d=.19)、饮食紊乱(饮食限制；d=.26)和媒体素养(现实主义怀疑论；d=.32)的控制条件，干预条件下的干预条件有所改善。讨论这项初步研究的结果表明，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障碍风险的潜在有用方法。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。
ObjectiveThis pilot study investigated the effectiveness of a social media literacy intervention for adolescent girls on risk factors for eating disorders.MethodA quasi-experimental pre- to post-test design comparing intervention and control conditions was used. Participants were 101 adolescent girls (M-age=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.ResultsSignificant 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).DiscussionThe 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.
