Note. Fewer than 5 participants had not obtained a college degree by 10-year follow-up and were omitted from analyses to prevent violating minimum cell size assumptions. Degrees of freedom reflect adjustments when heterogeneity of variances was found. Educational attainment: 1 = high school degree, 2 = college degree, 3 = graduate degree; marital status: 0 = not married, 1 = married; parental status: 0 = no children, 1 = have children.
