This study used structural equation modeling to conduct a first and second order confirmatory factor analysis (CFA) of a scale developed by McDonald and Moberg (2002) to measure three dimensions of social capital among a diverse group of middle- and upper-middle-class elementary school parents in suburban New York. A structural path model was created which best explains the linkages between race/ethnicity and our new construct "Total Social Capital." The CFA confirmed the three very distinct dimensions of social capital: parent-school, parent-parent, and parent-child. Fit indices also suggest the existence of a second order, global Total Social Capital factor comprised of all three dimensions of social capital. We show that Black, Hispanic, and mixed-race family status is associated with significantly diminished Total Social Capital, both directly and indirectly via socioeconomic status. This is one of the few studies to find decreased social capital even among middle- and upper-middle-class minorities.
