Capturing the self-others dichotomy of social media use: Affordances-actualizations-outcomes model
聚焦Instagram的被动使用，通过定性和定量方法揭示自我导向和他人导向两类可供性，并构建可供性-实现-结果模型，解释不同可供性的实现如何影响社会连接、积极情绪和整体满意度。
Focusing on the passive use of Instagram, we apply the affordance perspective to deeply explore its use and use-related outcomes. In the qualitative study, we uncover the affordances of focal social media features. Two distinct groups of affordances (self- and others-oriented) emerge. Following the grounded theory methodology, we develop the affordances-actualizations-outcomes model, explaining how immediate goals associated with features translate into outcomes. In the quantitative study, we test the model by applying structural equation modeling. Our findings confirm that actualizations of self- and others-oriented affordances are associated with distinct outcomes: social connectedness, positive affect, and overall satisfaction with Instagram experience.
