Note. N = 182. Dependent variable, binge drinking group, was coded: social binge drinker = 0 solitary binge drinker = 1. Gender was coded: male = 0, female = 1. Ethnicity was coded: racial/ethnic minority students = 0, White students = 1. Previous suicide attempt was coded: no attempts = 0, previous attempt = 1. R² = Nagelkere R². OR = odds ratio. CI = 95% confidence interval.
