Greater use of appearance-focused social media, such as Instagram, is associated with increased body dissatisfaction and eating disorder (ED) symptoms; however, questions remain about the mechanism connecting social media use to disordered-eating behaviors (DEBs). The proposed study evaluates how and for whom exposure to fitspiration or thinspiration on Instagram is associated with DEBs.
We will evaluate a hypothesized pathway from Instagram use to disordered-eating mediated by negative affect. We will test how individual differences in internalized weight stigma, trait self-esteem, and trait self-comparison moderate the pathway from social media use to negative affect. We will recruit 175 undergraduate women who report engaging in DEBs on average at least once per week over the past 3 months. Participants will complete a 7-day ecological momentary assessment protocol, during which they will report their Instagram use, affect, and engagement in DEBs.
Multi-level modeling will be used to assess moderated mediation. Results from this study will provide increased specificity about how Instagram usage is linked to eating pathology and who may be most vulnerable to experiencing distress.
Information about negative affect from Instagram and engagement in DEBs could contribute to the development of Just-In-Time Interventions for problematic social media use.
更多地使用以外观为重点的社交媒体,如 Instagram,与增加身体不满和饮食失调(ED)症状有关;然而,关于将社交媒体使用与饮食失调行为(DEB)联系起来的机制仍存在疑问。拟议的研究评估了在 Instagram 上接触健身灵感或瘦身灵感如何以及为何与 DEB 相关。
我们将评估从 Instagram 使用到通过负面情绪介导的饮食失调的假设途径。我们将测试内化体重耻辱感、特质自尊和特质自我比较的个体差异如何调节社交媒体使用到负面情绪的途径。我们将招募 175 名报告过去 3 个月内平均每周至少一次出现 DEB 的本科女性参与者。参与者将完成 7 天的生态瞬时评估方案,在此期间他们将报告他们的 Instagram 使用、情绪和 DEB 的参与情况。
多层次建模将用于评估中介调节。这项研究的结果将更具体地说明 Instagram 的使用方式如何与饮食病理学相关,以及谁最容易受到困扰。
来自 Instagram 的负面情绪信息和 DEB 的参与可能有助于为有问题的社交媒体使用开发及时干预措施。
