Ethnically and racially underrepresented adolescents are experiencing pubertal development earlier in life than prior cohorts and their White American peers. This early onset of puberty is partly attributable to ethnic-racial discrimination. To contribute to adolescents' resilience and posttraumatic growth in the face of ethnic-racial discrimination, parents' ethnic-racial identities may spill over into their parenting beliefs and practices. Parents who have a sense of belonging with and commitment to their ethnic-racial identities may be aware of discrimination and actively and consistently engage in practices that build supportive home environments to support their children's development in the context of ethnic-racial discrimination. To assess whether parents' ethnic-racial identity commitment predicted adolescents' resilience against ethnic-racial discrimination, we used multiple waves of survey data from adolescent siblings and their parents participating in the Adolescent Brain Cognitive Development study (N-adolescents = 1,651; N-families = 805; 35% Black, 37% Latinx, 3% Asian, 25% other ethnically and racially underrepresented youth; 49% boys, 50% girls, 1% gender nonconforming youth; Mage = 11.49, SD = 0.51). Results indicated that adolescents who experienced more frequent ethnic-racial discrimination than their siblings showed more advanced pubertal development. Parental ethnic-racial identity commitment reduced the relation between discrimination and pubertal development within a family. Results suggest that ethnic-racial identity commitment in parents can protect children when they experience ethnic-racial discrimination. Building on extant propositions related to resilience (Infurna & Luthar, 2018), the present study amplifies the depiction of resilience, yields recommendations for analysis of future research, and provides implications regarding the role of ethnicity-race in familial practices.
