title: Early Adolescent Peer Foundations of Late Adolescent and Young Adult Psychological Adjustment.
abstract: The long-term impacts of failing to establish autonomy and relatedness within close friendships are poorly understood. Adolescent behaviors undermining autonomy and relatedness in friendships at 13 were examined as predictors of friendship competence at 18 and depressive symptoms and social withdrawal at 21. A diverse community sample of 184 adolescents participated in self, peer, and observational assessments. Teens' inability to establish autonomy and connection with friends at 13 predicted decreases in friendship competence at 18 (ß=-.20,p=.02). Direct links to increases in depressive symptoms (ß=.34,p<.001) and social withdrawal (ß=.18,p=.03) were observed, with friendship competence partially mediating these relations. Results highlight the importance of problematic adolescent peer relationships as risk factors for the development of young adult internalizing symptoms.
