This article outlines research findings relevant to peer influence during adolescence. The multiple contexts of influence are described, including dyadic relationships, peer groups, and social networks. The article provides an overview of basic concepts relevant to peer influence such as homophily, selection, and socialization. Theoretic mechanisms of peer influence are introduced, including behavioral approaches to examining influence processes in peer interactions and identity-based theories focused on social comparison. Several factors that moderate peer influence are described, including individual, relationship-level, and contextual-level moderators. Finally, the role of peer influence in undermining the effectiveness of group intervention strategies for antisocial or high-risk youth is discussed, along with factors that may mitigate the extent of iatrogenic effects present in group treatment settings.
