Processes through which adolescents believe romantic relationships influence friendship quality.

Little is known about how romantic relationships influence adolescents' friendships. The purpose of this exploratory study was to identify behaviors through which adolescents believe romantic relationships influence friendship quality. Intimate exchange, co-rumination, encouragement, and conflict resolution were identified as processes through which romantic relationships influence friendship quality. Associations between these variables and friendship quality were investigated with 340 adolescents. Adolescents believed these processes occurred frequently within friendship. Gender differences suggest girls may be more sensitive to the influence of romantic partners on their friendships than are boys. Hierarchical regression analyses revealed that greater intimacy, encouragement, compromise, and less co-rumination were associated with more positive beliefs about friendship quality when one friend has a girlfriend or boyfriend. Greater co-rumination and less encouragement were predictive of negative friendship quality. Thus, these processes may represent avenues through which romantic relationships positively and negatively influence friendship quality. Findings highlight the need to understand friendships as part of a complex social network that includes romantic ties.
