What do couples’ activities and behaviors on Instagram reveal about the quality of their relationships? To answer this question, we surveyed couples (N = 178) about their perceptions of their relationships and analyzed 3,270 of their recent Instagram posts. Actor and partner effects were found between relational quality and engagement with the relationship on Instagram (i.e., the number of couple pictures and partner-initiated likes and comments). There were also actor effects of attention to Instagram alternatives on the perceived quality and actual pursuit of alternative partners, as well as a partner effect on alternative quality. The findings contribute to extending the investment model to the digital age and have methodological implications for understanding relationship dynamics on visual social network sites.

夫妻在Instagram上的活动和行为对他们的关系质量有何启示？为了回答这个问题，我们调查了情侣（N= 178）了解他们对人际关系的看法，并分析了他们最近在Instagram上发布的3,270条信息。在关系质量和与Instagram的关系参与度之间（即，情侣照片的数量和伴侣发起的喜欢和评论），发现演员和伴侣的影响。注意Instagram替代品对演员的感知质量和实际追求的演员效应，以及对替代品质的伙伴效应。这些发现有助于将投资模型扩展到数字时代，并对理解视觉社交网站上的关系动态具有方法学意义。
