N = 3,211. MPQ = Multidimensional Personality Questionnaire.
“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. The values for “effect of initiation on trait level” reflect the extent to which the level of a trait changed after the onset of drinking.
