the rates of growth, of adolescent alcohol abuse. We fitted a latent growth curve model to eight waves of past-year alcohol abuse self-reported annually from grade 7 through 2 years post-high school to examine the developmental trajectories of alcohol abuse. Intervention status, NR3C1 genotype, as well as their interaction, were included to predict the intercept and linear slope of the latent growth curve model. Based on prior research, we expected that participants would demonstrate substantial increase in alcohol abuse throughout adolescence and that individuals carrying susceptible NR3C1 genotypes would benefit more from the Fast Track intervention than individuals without susceptible genotypes, therefore showing slower rates of increase.
