Abstract
A systemic perspective is adapted in this account of close friendships and romantic relationships in adolescence. Data from a series of studies conducted on dyads of close friends and romantic partners illustrate how, in each relationship, partners simultaneously negotiate closeness and the expression of individual needs. Two relational types-interdependent and disengagedwere consistently found across all adolescent age groups. Interdependent partners were clearly capable of co-operation. Disengaged partners, although they identified each other as closest friends, appeared incapable of restraining competition to act co-operatively. Differences between the two friendship types were evident at each developmental stage. A three-stage developmental model of adolescent friendship is proposed based on age-related issues as reflected in the two relational types.
