Self-regulation as a key boundary condition in the relationship between social media use and well-being.

The use of social media can have positive and negative effects on psychological well-being. The present article proposes that self-regulation and the related concept of self-control act as central boundary conditions of this relationship. Successfully self-regulated social media use can bolster psychological well-being through mood management and emotion-focused coping as well as through intrinsic need satisfaction. In contrast, poorly self-regulated forms of social media use can result in goal conflict, i.e., the displacement of, and distraction from other activities, which may negatively affect well-being. The article covers relevant factors that influence (un-)successful self-regulation of social media use, including media affordances, social dynamics, as well as trait and state user characteristics, including media habits and mindfulness.
