Note. Estimates for depressive symptoms, anxiety, and frequency of alcohol consumption in the past 30 days were standardized (M=0, SD=1) and served as the outcome variable in separate linear regressions. Binge drinking in the past 30 days and was the outcome variable in a logistic regression. Models control for income quartiles, household type (single-parent vs dual-parent/multigenerational) and education (college vs no college).
