This research explored whether Black male adolescents' (N=453; Mage =13.72, SD=1.33) perceptions of parental racial socialization (i.e., behavioral racial socialization) and school racial climate (i.e., equitable school racial climate) were associated with prosocial outcomes (i.e., prosocial behaviors and positive relations with others) across three waves of adolescence. This study also explored whether youth's beliefs about the extent to which Black individuals and other marginalized communities are united by experiences of oppression (i.e., oppressed minority ideology) and empathy mediated these associations. Structural equationmodeling indicated that parental behavioral racial socialization at Wave 1 and positive relations with others at Wave 3 were positively linked through youth's oppressed minority ideology and empathy at Wave 2. Thus, Black male adolescents who relate to other marginalized communities through a shared experience of oppression and feel empathy towards others' lives possess skills that translate their lessons about race and racism into positive relations with others.
