Note. Significant beta estimates (p<0.05) are shown in bold. All beta estimates are unstandardized for both binary and continuous outcomes, denoted by b or c, respectively. Standard errors are shown in parentheses following each unstandardized beta estimate. Race (Racial Minorities=1, White=0); Ethnicity (Hispanic/Latinx=1, Not Hispanic/Latinx=0). Education (College or greater=1, Other=0). Employment/student status (Employed/student=1, Unemployed=0). Models controlled for survey sample (if relevant) and income.
