Analyses first examined the moderating effects of the target teen's prior experience of support from their mothers, and of their observed tendency to recant their own position while appearing unconvinced in disagreements with their mothers. Hierarchical regression analyses predicted age 16 teen substance use from teen use at age 15, followed by teen gender and family income, level of peer substance use at 15, maternal support and adolescent recantations, and the interaction of peer use with both maternal support and adolescent recantations. Results are presented in Table 2. As expected, a significant effect of peer use at 15 in predicting future teen substance use was found. Also as hypothesized, both familial experience variables moderated the effect of peer substance use on relative changes in teen substance use over the following year. Results are depicted in Figure 1, which presents regression lines for teens one standard deviation above and below the mean in maternal support and adolescent recantations, using standardized scores on the x- and y-axes. As Figure 1 shows, peer substance use was more likely to predict future relative changes
