Note. The final hierarchical multivariable logistic regression models for risk and protective factors are presented here. SES = socioeconomic status; AOR = adjusted odds ratio; SE = standard error; CI = confidence interval. Female gender (coded 0 = male, 1 = female); Washington State (coded 1 = Washington State, 0 = Victoria). Pseudo R2 = McFadden’s R2; Adjusted R2 = McFadden’s Adjusted R2. Bolded effects are significant at p < 0.05.
