Despite increasing empirical research documenting the association between parental ethnic-racial socialization and youth of color's psychosocial well-being, evidence on the extent to which ethnic-racial socialization practices are linked to youth outcomes and potential variation in these relations remains equivocal. In the current study, a meta-analysis of 102 studies with 803 effect sizes and 27,221 participants reveals that overall ethnic-racial socialization was positively, albeit modestly, associated with self-perceptions, interpersonal relationship quality, and internalizing behavior. Ethnic-racial socialization's overall association with externalizing behavior was nonsignificant. Moreover, ethnic-racial socialization's connection to psychosocial outcomes varied by the subtype that parents used, the developmental stage and race/ethnicity of the target child, and the reporter of ethnic-racial socialization. In particular, cultural socialization was positively associated with self-perceptions and interpersonal relationship quality and negatively associated with externalizing behaviors. In addition, ethnic-racial socialization's positive association with self-perceptions was strongest in early adolescence and among African American youth. These findings underscore the complexity of parental ethnic-racial socialization practices and the need for a nuanced perspective on it. Implications for parenting practices and future research are discussed. (PsycINFO Database Record (c) 2020 APA, all rights reserved).
