This study examined gender differences in adolescents' behavior during conflict resolution tasks with their best friends. It also examined gender differences in adolescents' descriptions of those friendships. Thirty-nine adolescents were videotaped while discussing unresolved problems with their best friends. In addition, adolescents completed the Friendship Questionnaire (Furman & Adler, 1982). The results indicated that there were significant gender differences. On the conflict resolution tasks, females were rated lower in withdrawal and higher in communication skills and support-validation than were males. On the Friendship Questionnaire, males rated their relationships with best friends higher in conflict than did females. Methodological considerations are discussed.
