ABSTRACT Objective Black American adolescents are beleaguered with the most frequent and severe experiences of racial discrimination (RD) among their peers. To protect Black adolescents’ mental health and developmental outcomes from the pernicious impact of discrimination, parents and other proximal adults and peers often utilize racial socialization (RS), or communications and behaviors emphasizing the importance of race and the harms of racism. While several recent RS reviews have been conducted across ethnicity, a modern review investigating RS practices related to and predictive of Black adolescent psychosocial outcomes is needed. Method To ground our critical systematic review of 45 articles, we first highlighted the ways RD impacts the lives of Black adolescents. Then, drawing from integrative models for Black youth development, we synthesized recent psychological, academic, and sociocultural literatures to describe the role of RS in Black adolescents’ wellness. Results The impact of various tenets of RS was seen most clearly as a protective factor against RD with respect to adolescents’ mental health (e.g. depression), academic achievement (e.g. GPA), and sociocultural identity (e.g. public and private racial regard) development. Cultural socialization, a strategy related to extolling pride for one’s race, was the most consistent RS protective factor, with novel RS constructs (e.g. parental competency) emerging as a method to buffer youth internalizing and externalizing problems. Conclusions Recommendations are made for future research on understudied components of RS and multiple methods and reporters to capture a more holistic depiction of RS practices. We emphasize preventative and intervening approaches to reduce the impetus for RS and its impact, including burgeoning clinical and community-level programs and the importance for provider training to yield positive mental health outcomes for Black adolescents.
