Peer attachment might provide individuals with opportunities to build their sense of self-worth. The purpose of this paper was to meta-analytically review literature on peer attachment and self-esteem. A total of 22 articles reporting 24 studies documenting correlations between peer attachment and self-esteem in adolescents and emerging adults were included in this meta-analysis. Of these studies, most examined links between global peer attachment and self-esteem, while few studies reported any associations between specific dimensions of peer attachment (i.e., trust, communication, and alienation) and self-esteem. Results showed significant correlations between peer attachment and self-esteem, consistently found both in studies focused on global attachment as well as in studies including specific attachment dimensions. Furthermore, since a significant heterogeneity was found across the studies, the effects of various categorical and continuous moderators related to characteristics of the study samples and designs were tested. Implications of these findings for future research are discussed.
