In predicting to volume of alcohol use (Part II, lower panel of Table 3), again both parent and peer alcohol use at Grade 6 were significantly associated with a higher intercept at Grade 6. However, parent alcohol use at Grade 6 was negatively associated with the slope of alcohol volume; likely indicating that because of the initially relatively high levels associated with this predictor there was less-than-average growth across the middle school period. Peer alcohol use was positively associated with the slope of alcohol volume. Prediction from the change scores indicated that increases in peer alcohol use from Grades 6 to 8 were associated with increases in the volume of use in the same periods. Note that none of the paths from the Grade 6 alcohol intercepts to the change scores were significant.
