Total n of substance users = 424, n substance-using girls = 312, n substance-using boys = 102; Bolded percentages note significant gender differences as identified by X2 tests of independence; Means in the same column that are denoted by the same subscript are significantly different from one another (p < .05) as indicated by a Tukey's HSD post hoc test in a multivariate ANOVA.
ANOVA = analysis of variance; SD = standard deviation.
