ABSTRACT
Scholars of youth civic development have assessed agency using a wide range of constructs, including motivation, efficacy, empowerment, and sociopolitical control. We propose a multidimensional framework and describe the development and validation of a measure of civic agency, conceptualized as competence, drive, individual power, and collective power. In Study 1, we developed a set of items and employed exploratory factor analysis with a pilot sample of adolescents (N = 295, M
age = 17.1, 65.4% youth of color, 47.9% female, 15.8% nonbinary), which supported our hypothesized four-factor model of civic agency. In Study 2, we conducted confirmatory factor analysis of our final items with a separate adolescent sample (N = 1120, M
age = 16.2, 73.0% youth of color, 55.7% female, 23.3% nonbinary), which demonstrated measurement invariance on race/ethnicity, gender, and age. In Study 3, we validated our scale in a sample of young activists (N = 342, M
age = 19.1, 57.6% youth of color, 72.6% female, 23.0% nonbinary). Confirmatory factor analysis supported a four-dimensional hierarchical structure and we established measurement invariance between adolescents and young adults. Overall, the 16-item Civic Agency Measure consistently demonstrated validity and reliability. We discuss the utility of our work for advancing sociopolitical development theory and supporting adolescents’ efforts for social change.
