N = 3,211. Gender (1 = male). “Intercept” values reflect model-derived scores at age 11. Values for “age,” “age2,” and “age3” reflect the linear, quadratic, and cubic change, respectively, per year in that scale after the age of the intercept. “Gender on initiation effects” reflects the effect of including gender at Level 2 as a predictor of individual differences in the initiation effects at Level 1. This coefficient denotes whether the magnitude of the effects of alcohol use initiation on a trait level was significantly different between men and women.
