In this 14-day study, we tested whether Latinx adolescents' (M_age  = 12.76 years, 52% female; 52% U.S. born; N = 21) and parents' (95% female; 24% U.S. born) daily discrimination experiences were associated with their own and other's daily affective states. Results indicated that on days when adolescents reported discrimination, they reported higher negative affect and marginally lower positive affect and, interestingly, parents reported higher positive affect. On average (i.e., across the 2-week period), adolescents' discrimination was associated with higher adolescent negative affect and lower parent positive affect. Together, findings suggest that Latinx adolescents' discrimination experiences are linked to their own affective states and their parents'. Results underscore how discrimination is linked to the affective states present in family contexts.
