Evaluate the feasibility, acceptability, and preliminary efficacy of a self-criticism intervention addressing the link between appearance-motivated social media use and eating disorder risk. Another condition, designed to help users curate their social media feed to reduce negative impacts on wellbeing, was also trialed as an active and credible comparison.
University students aged 17-25 (N = 170) were screened and randomized (n = 130) to the self-criticism intervention, social media curation, or waitlist control group. The intervention comprised self-guided cognitive behavior therapy delivered in four modules over 1 week. Primary outcomes were feasibility and acceptability. Secondary outcomes were appearance motivations for social media use, appearance comparison, self-criticism, body image flexibility, and disordered eating (at baseline, one-week postrandomization, and two-weeks postrandomization).

Participants completed an average of 82% of the intervention modules and 77% of the homework exercises within the week allocated. The intervention was well-accepted; participants reported a range of positive aspects, alongside suggested modifications to the intervention and study design to improve acceptability. Group by time interactions suggested groups changed at a different rate on three secondary outcomes; between-groups effect sizes suggested this was due to greater improvements in the self-criticism group than waitlist control.
This was the first study to evaluate an intervention for the link between appearance-related social media use and eating disorder risk for young adults. Positive findings relating to feasibility, acceptability, and preliminary efficacy suggest a larger randomized controlled trial, with modifications to the intervention and study design, is warranted.
Appearance-related social media use has been linked to poorer body image and disordered eating, necessitating treatments that can disrupt this relationship. The self-criticism intervention evaluated in this study shows promise as a strategy to address this need. It is the first intervention focused on appearance-related social media use to be designed for and tested in young adults, who are at heightened risk of developing an eating disorder.
评估针对因追求外表而使用社交媒体与饮食失调风险之间关联的自我批评干预措施的可行性、可接受性和初步疗效。还试用了另一种干预措施，旨在帮助用户策划其社交媒体提要以减少对幸福感的负面影响，作为积极和可信的对照。
筛选并随机分配（n=130）年龄在 17-25 岁的大学生（N=170）至自我批评干预组、社交媒体策划组或候补对照组。干预措施包括在一周内分四个模块提供自我引导的认知行为疗法。主要结局是可行性和可接受性。次要结局是社交媒体使用的外表动机、外表比较、自我批评、身体意象灵活性和饮食失调（基线时、随机分配后一周和随机分配后两周）。
ACTRN12621000353897。
参与者平均完成了 82%的干预模块和一周内分配的 77%的家庭作业。干预措施得到了很好的接受；参与者报告了一系列积极方面，以及对干预措施和研究设计的修改建议，以提高可接受性。组间时间交互表明，三组在三个次要结局上的变化速度不同；组间效应大小表明，这是由于自我批评组的改善大于候补对照组。
这是第一项针对年轻人因外表相关的社交媒体使用与饮食失调风险之间的关联的干预措施的研究。可行性、可接受性和初步疗效的积极发现表明，有必要进行更大规模的随机对照试验，并对干预措施和研究设计进行修改。
与外表相关的社交媒体使用与较差的身体意象和饮食失调有关，因此需要能够打破这种关系的治疗方法。本研究评估的自我批评干预措施显示出有希望成为满足这一需求的策略。这是第一个针对年轻人因外表相关的社交媒体使用而设计和测试的干预措施，年轻人患饮食失调的风险更高。
