Middle-class African American mothers and adolescents (n=81) participated in a dyadic interaction task in early adolescence (M=13.06 years, SD=1.27) and then again 2 years later (M=15.01 years, SD=1.27). Following the task, mothers and adolescents rated their own and their partner's support and involvement in the task; observers rated videotaped interactions for the same dimensions. African American mothers perceived adolescents' behavior in the interactions more positively than did observers, and both mothers and observers viewed mothers' behavior as more positive than adolescents' behavior. With observers' ratings controlled, early adolescents' more negative perceptions of their mothers' interactions led to less trust and communication with mothers 2 years later, but subjective understanding did not influence later ratings of conflict intensity.
