According to attachment theory, children's early experiences with their primary caregivers, in terms of protection and security, are the basis for socioemotional development and for the establishment of close relationships throughout their lives. During adolescence, friends and peers become a primary developmental environment, and thereby establishing quality bonds with peers will foster good psychological adjustment. The aim of the present study was to review the evidence on the relation of parental attachment to the quality of peer relationships during adolescence. A systematic review was conducted according to the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The search was performed in the PsycInfo, Scopus, and Web of Science (WOS) databases. Inclusion criteria were studies published since 2001, in English, that are academic publications in scientific journals, that explore adolescence, and that analyze the relationship between attachment styles and adolescent peer interactions. The search resulted in 1438 studies, of which 19 studies met the criteria and were included in the review. The results highlighted that secure attachment predicts and promotes the creation of affective relationships with peers and friends based on communication, support, intimacy, trust, and quality. In addition, some variables, such as gender differences or family characteristics, were found to be involved in attachment and provide a better understanding.
