Social media movements centered on body positivity and body neutrality both encourage healthy attitudes toward the physical body; however, these movements are conceptually distinct and may have unique influences on body image. This study examined how brief exposure to different types of body acceptance and weight-stigmatizing content affects body image and mood. Participants consisted of women and gender-diverse individuals (N = 326) who completed an online survey and were randomly assigned to view one of four TikTok video compilations: body neutrality, body positivity, weight-stigmatizing, or travel (control) content. Exposure to body positivity and body neutrality content was associated with improvements in functional appreciation, self-objectification, body dissatisfaction, and negative affect. Moreover, although participants across body-focused conditions reported thinking about their appearance to a similar extent, those in the body-positive and body-neutral groups reported more frequent positive appearance-related thoughts than those in the weight-stigmatizing or control conditions. Importantly, differences emerged between the two body acceptance conditions, such that body neutrality was uniquely effective in reducing self-objectification relative to weight-stigmatizing content, while body positivity significantly enhanced positive affect. Moderation analyses revealed marginal interactions, suggesting that the effect of content on body dissatisfaction varied by gender identity, while positive affect varied by perceived body silhouette. Overall, these findings indicate that body-positive and body-neutral content on TikTok may serve as beneficial alternatives to weight-stigmatizing media, though each approach may yield distinct benefits especially in consideration of individual identity characteristics.
以身体积极态度和身体中立态度为中心的社交媒体运动都鼓励对身体形成健康的态度；然而，这些运动在概念上是不同的，可能对身体形象有独特的影响。本研究考察了短暂接触不同类型的身体接纳和体重歧视内容如何影响身体形象和情绪。参与者包括女性和性别多样化的个体（N = 326），他们完成了一项在线调查，并被随机分配观看四个TikTok视频合集中的一个：身体中立、身体积极、体重歧视或旅行（对照）内容。接触身体积极和身体中立内容与功能欣赏、自我物化、身体不满和负面影响的改善有关。此外，尽管关注身体状况的参与者报告说他们对自己外表的思考程度相似，但身体积极组和身体中立组的参与者报告的与外表相关的积极想法比体重歧视组或对照组的参与者更频繁。重要的是，两种身体接纳状况之间出现了差异，即相对于体重歧视内容，身体中立在减少自我物化方面具有独特的效果，而身体积极显著增强了积极情绪。调节分析揭示了边缘交互作用，表明内容对身体不满的影响因性别认同而异，而积极情绪因感知的身体轮廓而异。总体而言，这些发现表明TikTok上的身体积极和身体中立内容可能是体重歧视媒体的有益替代品，尽管每种方法可能会产生不同的益处，尤其是考虑到个体身份特征时。
