We tested for moderation on the A, C, and E components that peer deviance and alcohol use frequency shared using the bivariate moderation model (shown in Table 3). The path estimates for the bivariate moderation model are shown in Figure 3. Since moderation was retained on the cross c path, it was not appropriate to use the extended univariate model. Therefore we continued to test for moderation on the unique a, c and e paths in the bivariate moderation model. As shown in Table 3, there were significant moderation effects on the unique A and E components. Figure 3 shows the changes in the raw variance of the shared and unique A, C, and E components as a function of peer deviance. Genetic and environmental influences increased under conditions of higher peer deviance, and were attenuated under conditions of lower peer deviance.
