Although studies on peer relations acknowledge that having friends constitutes a protective factor against being victimized by peers at school, it is not enough for this factor to operate. The quality of these friendships does play a role too. The present study explored the moderating role of friendship-quality dimensions (closeness, support, disclosure, and affection) on peer victimization and wellbeing. 614 young adolescents (4th to 6th graders, 50.1 % girls) were assessed three times over 1 year. Analyses were conducted to determine moderation effects, differentiated by gender. Results showed that only disclosure and support interact with victimization and affect wellbeing, especially for girls. Implications for studying peer relations, acknowledging gender differences, are discussed.
