The development of anti-racist ideology in adolescence and emerging adulthood is informed by parent socialization, parenting style, and cross-race friendships. This study used longitudinal, multi-reporter survey data from White youth and their parents in Maryland to examine links between parents' racial attitudes when youth were in eleventh grade in 1996 (N = 453; 52% female; M[subscript age] = 17.12) and the youths' anti-racist ideology (acknowledgment of anti-Black discrimination and support for affirmative action) 1 year after high school in 1998. This study also examined whether these associations varied based on authoritative parenting and the number of cross-race friendships. Positive parent racial attitudes toward racially and ethnically minoritized populations predicted higher anti-racist ideology in the independent contexts of more cross-race friendships and low authoritative parenting.
