There has been a wealth of recent reviews, meta-analyses, and empirical studies on the relationship between social media and well-being. However, scholars still have a limited understanding of how and why social media influences and relates to well-being. In this half-day workshop, academic and industry researchers will engage in cooperative problem-solving activities around the current state of social media and well-being to identify open questions and brainstorm design solutions. The overall goals of this workshop are to 1) foster discussion in order to bridge gaps and map future directions and 2) share the day's discussion with the field more broadly.
