This study investigates the role of character strengths in peer relationships among early adolescents. A sample of students (N = 339; [X bar] age = 12.84 years, 53.1% female) nominated friends in the classroom and completed assessments of character strengths, the desirability and importance of character strengths in a friend, and friendship quality. Results indicate that the character strengths of honesty, humor, kindness, and fairness were most desirable and important in a friend. Perspective, love, kindness, social intelligence, teamwork, leadership, and humor were associated with higher peer acceptance. Dyadic analyses of mutual best friends suggested that a number of character strengths were also positively related to friend-rated friendship quality. Overall, the results demonstrate the relevance of character strengths for positive peer relationships in adolescents.
