Racial and ethnic socialization are an integral part of African American parenting strategies. Varied conceptualizations and operationalizations of racial and ethnic socialization exist within the literature with limited evidence of the validity of existing measures. The purpose of this study is to develop a comprehensive definition of racial and ethnic socialization and to validate a new measure termed the Adolescent Racial and Ethnic Socialization Scale (ARESS). Using Confirmatory Factor Analysis (CFA), findings from 218 African American adolescents (grades 9–12) support the multidimensional nature of racial and ethnic socialization. Results also indicate that racial and ethnic socialization are distinct constructs reflecting the utility of this instrument for African American youth.
