We analyzed 1,596 sub-conversations within 451 direct message (DM) conversations from 67 teens (ages 13-17) who engaged in private discussions about body image on Instagram. Our findings show that teens often receive support when sharing struggles with negative body image, participate in criticism when engaging in body-shaming, and are met with appreciation when promoting positive body image. Additionally, these types of disclosures and responses varied based on whether the conversations were one-on-one or group-based. We found that sharing struggles and receiving support most often occurred in one-on-one conversations, while body shaming and negative interactions often occurred in group settings. A key insight of the study is that private social media settings can significantly influence how teens discuss and respond to body image. Based on these findings, we suggest design guidelines for social media platforms that could promote positive interactions around body image, ultimately creating a healthier and more supportive online environment for teens dealing with body image concerns.

翻译：我们分析了来自67名青少年（年龄13-17岁）的451段Instagram私信对话中的1,596个子对话，这些青少年在Instagram上参与了关于身体意象的私下讨论。研究发现，当青少年分享负面身体意象困扰时通常会获得支持，参与身体羞辱时会共同进行批评，而倡导积极身体意象时会得到赞赏。此外，这类自我表露与回应方式会因对话是一对一还是群组形式而存在差异。我们发现，分享困扰与获得支持最常发生在一对一对话中，而身体羞辱与负面互动则多出现在群组场景中。本研究的一个关键发现是：社交媒体私密环境会显著影响青少年讨论和回应身体意象的方式。基于这些发现，我们为社交媒体平台提出了设计建议，以促进围绕身体意象的积极互动，最终为关注身体意象问题的青少年创造更健康、更具支持性的网络环境。
