This research explores how sharing photos on social networking sites contributes to an individual's identity expression. A mixed-methods survey was conducted with Instagram users to understand how they frame, annotate, and share their lives with others through digital photography. Results from a serial multiple mediator model reveal that the frequency with which individuals post on Instagram predicts their need for personal-visual identity and this relationship is mediated by self-objectification and self-confidence. Previous research supports the positive association between frequent posting of photographs on social networking sites and visual identity expression. The current study provides evidence for mechanisms that enable this relationship. Implications for impression management theory and visual communication research are discussed.

Instagram 上的故事：与个人视觉识别需求相关的因素

这项研究探讨了在社交网站上分享照片对个人身份表达的影响。对 Instagram 用户进行了一项混合方法调查，以了解他们如何通过数码摄影来构图、注释和与他人分享他们的生活。串行多重中介模型的结果表明，个人在 Instagram 上发帖的频率可以预测他们对个人视觉身份的需求，而这种关系是由自我客观化和自信来调节的。先前的研究支持在社交网站上频繁发布照片与视觉身份表达之间存在正相关。目前的研究为促成这种关系的机制提供了证据。讨论了印象管理理论和视觉传播研究的意义。
