Viewing body-positive content on social media can benefit women's body image. Previous research has conceptualised body positivity broadly, and therefore it remains unclear whether some components are more useful than others. This study examined the impact of body appreciation or body functionality messages (in addition to a mixed condition) overlaid across different image types to influence women’s body image. Young women (17–30 years, M_age = 21.53, N = 308) completed an online survey in which they were randomised to view either fitspiration or diverse images overlaid with messaging focusing on body appreciation, body functionality, or a combination. Participants completed pre- and post-test measures of appearance and functionality satisfaction, body appreciation, and body objectification / conceptualisation. Post-test measures of social comparison and perceptions of models were also taken. Results showed that message type did not interact with image type. Rather, exposure to diverse images increased appearance satisfaction and body appreciation, with no changes to functionality satisfaction (vs a decrease for the fitspiration condition). All conditions improved in self-objectification. Further, diverse images resulted in more favourable social comparisons. Our findings consider body positive content in a controlled way and show no differences across body appreciation or body functionality themes.

在社交媒体上查看积极身体的内容有利于女性的身体形象。之前的研究对身体积极性进行了广泛的概念化，因此尚不清楚某些成分是否比其他成分更有用。这项研究考察了身体欣赏或身体功能信息（除了混合条件之外）叠加在不同图像类型上对女性身体形象的影响。年轻女性（17-30 岁，M_年龄 = 21.53，N  = 308）完成了一项在线调查，其中她们被随机分配观看健身或覆盖着关注身体欣赏、身体功能或组合的信息的不同图像。参与者完成了外观和功能满意度、身体欣赏和身体客观化/概念化的测试前和测试后测量。还进行了社会比较和模型认知的测试后测量。结果表明消息类型与图像类型没有交互作用。相反，接触不同的图像增加了外观满意度和身体欣赏，而功能满意度没有变化（相对于健身条件的下降）。自我客体化的所有条件都得到改善。此外，多样化的图像会带来更有利的社会比较。我们的研究结果以受控的方式考虑了身体积极的内容，并且在身体欣赏或身体功能主题方面没有显示出差异。
