* Model 1: Single factor, loadings constrained to be equal across all six sex-race/ethnicity groups.
Model 2: Single factor, loadings allowed to vary across all six groups.
** Chi-square test (5 df) p-value comparing factor loadings across the six groups.
NHW = Non-Hispanic White; NHB = Non-Hispanic Black; Hisp = Hispanic.
