Unless otherwise stated, variables were entered dummy coded with 0 = “No” and 1 = “Yes”. Degrees of freedom for the F test corresponding to model 1 are (6153), corresponding to model 2 are (3150), and corresponding to model 3 are (5145)
*p < 0.05; **p < 0.01; ****p < 0.0001
^aHigher education “Yes” > 10 years of education, higher education “No” ≤ 10 years of education
