Parental monitoring is a robust family-level predictor of youth well-being. Identification of variations by gender and/or race/ethnicity in parental monitoring has important implications for tailoring parenting practices. However, valid comparisons can only be conducted if cross-subpopulation measurement equivalence is established. Although measurement equivalence testing is widely used, it rarely (a) assesses intersectional identity (i.e., identity reflecting multiple factors such as race/ethnicity and gender) or (b) involves generating scores adjusted for nonequivalence. This is the first known study to do both with a parental monitoring measure. Measurement equivalence by sex (proxy for gender), race/ethnicity, and intersectional identity (sex by race/ethnicity) was assessed in the five-item Parental Monitoring Questionnaire administered to middle-school-aged Black, Latinx, and White girls and boys. Data were drawn from the second follow-up of the Adolescent Brain Cognitive Development Study (
