The transformation framework (Nesi et al., 2018a, 2018b) describes the ways in which the features of social media shape adolescents’ peer experiences. In the current chapter, we build on this work in three ways. First, we expand on our previous conceptualization to consider the role of algorithms as a key feature of social media. Second, we offer an updated review of the ways in which social media transforms a range of peer experiences, including peer status, peer influence, victimization, and other interpersonal behaviors and skills. Finally, we describe the translational implications of the transformation framework for adolescents’ educators, providers, and parents.
