Figure 3 presents the test of the mediated moderation hypothesis. Consistent with this hypothesis, the results depicted in Figure 3 show that the SAAF–T × DRD4 status interaction effect on changes in substance use became nonsignificant, changing from β = −.72, p < .01 when the interaction effect on intervention-targeted protective parenting was not included in the SEM to β = −.39, p > .05 when the interaction effect on intervention-targeted parenting was included in the SEM. As expected, increases in intervention-targeted parenting forecast decreases in substance use, β = −.56, p < .01. A Wald test confirmed the significance of this indirect effect (Wald χ2(1) = 4.44, p < .035).
