Some adolescents use social media platforms, such as Instagram, for sexualized self-presentation, which includes posting images in which someone is scarcely dressed, has a sexy gaze or in which sexual willingness is suggested. These behaviors could be a first step towards sexting. Given that adolescents are highly influenced by peer perceptions, this study uses the prototype willingness model to assess how teenagers' perceptions of others could influence their posting behaviors. The study was conducted among 2626 students ( = 1530; 58.4% girls) between the ages of 14 and 21 ( = 16.14; = 1.02) in 10 secondary schools in the Dutch-speaking community in Belgium. The results show that older adolescents and girls were more likely to post images of themselves on Instagram. The models showed that peer norms and willingness and attitudes were significantly associated with posting intention. The perceived norms of adolescents' parents were not significantly related to the behaviors. There were also significant associations between perceived similarity, prototype favorability and the willingness to engage in sexualized self-presentation on Instagram. The implications for education and practice are discussed.
一些青少年使用社交媒体平台，如 Instagram，进行性化的自我呈现，包括发布穿着暴露、眼神性感或暗示性意愿的照片。这些行为可能是发送色情短信的第一步。鉴于青少年深受同龄人的影响，本研究使用原型意愿模型来评估青少年对他人的看法如何影响他们的发布行为。该研究在比利时荷语区的 10 所中学中进行，共有 2626 名学生（=1530；58.4%为女生），年龄在 14 至 21 岁之间（=16.14；=1.02）。结果表明，年龄较大的青少年和女孩更有可能在 Instagram 上发布自己的照片。模型表明，同伴规范、意愿和态度与发布意图显著相关。青少年父母的感知规范与行为没有显著关系。青少年对父母的感知相似性、原型有利性和在 Instagram 上进行性化自我呈现的意愿之间也存在显著关联。讨论了教育和实践的意义。
