Note: Binomial logistic regression was used in all analyses to predict differences in demographics across study condition (0 = control; 1 = intervention). Each demographic factor was compared across conditions individually, in separate models. Any variable that differed between groups at p < .10 was included as a potentially confounding variable in follow-up models testing for the effect of the intervention (highlighted in bold). Exp(B) is a odds ratio, with 1 meaning no difference, values under 1 meaning slightly less likely, and values over 1 meaning more likely to occur in the intervention compared to control group. English language proficiency scores ranged from 1 to 4, with 4 being completely English proficient and 1 being no English proficiency.
