Measurement Equivalence of Family Functioning and Psychosis Risk Measures in the Adolescent Brain Cognitive Development^SM Study

Decades of research show a clear link between family factors and psychopathology. Family functioning varies across cultures, suggesting potential cultural differences in the association between family factors and psychopathology. In addition, assessing family functioning generally involves tools not systematically validated for diverse cultural backgrounds. Using the Adolescent Brain Cognitive Development^SM data (N = 11,864), this study found: (a) full scalar invariance was tenable for the Children's Reports of Parental Behavior Inventory (CRPBI) and Prodromal Questionnaire-Brief Child Version (PQ-BC) across race/ethnicity, but not for the Family Environment Scale (FES) and Parental Monitoring Survey (PMQ); (b) the CRPBI and PMQ were significantly associated with the PQ-BC, and (c) all three family scales had equivalent relations with the PQ-BC across groups. This highlights the importance of evaluating scales for measurement invariance across race/ethnicity. Results also help to connect specific family factors to the etiology of psychosis risk among U.S. children and adolescents.
