The goal of this study was to examine the association between interpersonal competencies in the peer domain and feelings of false self in romantic relationships. Participants included 238 White, middle-class boys and girls (Grades 10 and 11). Students completed self report measures of false self in romantic relationships and interpersonal competency in same-sex and other-sex peer relationships. Results indicate that boys experience higher levels of false self in romantic relationships when compared to girls. Conflict management in the context of other-sex peer relationships was negatively associated with feelings of false self in romantic relationships for both boys and girls. For girls, competency in the domain of emotional support in same-sex peer relationships was associated with lower levels of false self in romantic relationships. For boys, competency in the domains of self-disclosure and asserting influence with same-sex peers was associated with lower levels of false self in romantic relationships.
