Demographic variables are reported as percentage non-white, college educated, having a college educated mother or guardian, and indicating socially desirable reporting. Pearson correlation coefficients are calculated for all continuous variables and point-biserial correlations are calculated for binomial measures. All questionnaire items were on a six-point scale (1 = “Strongly Disagree”; 6 = “Strongly Agree”). ^∗p < 0.05, ^∗∗p < 0.01, ^∗∗∗p < 0.001.
