Social Media and Psychological Well-Being Among Youth: The Multidimensional Model of Social Media Use.

Social media use is almost ubiquitous among adolescents and emerging adults. Although much has been studied about the psychological implications of social media use, there is currently no integrative model in which multiple dimensions of social media are considered. The goal of this theoretical article is to introduce the Multidimensional Model of Social Media Use (MMSMU), which aims to provide a useful framework for researchers and practitioners to study and understand young people's social media use in relation to their psychological well-being. The model attends to three major dimensions: activities performed on social media, motives for social media use, and communication partners connected through social media. We present empirical evidence showing whether each dimension is associated with better or poorer well-being and identify or propose mechanisms explaining the associations. Before concluding the article, we discuss clinical implications and possible ways to further expand the proposed model.
