Intervention Effects on the Slopes of Drug Use and Vulnerability Cognitions by Family Risk and DRD4 Status

Subgroups	Slope of Drug Use				Slope of Vulnerability Cognitions
Subgroups	Coefficients	SE	t	p	Coefficients	SE	t	p
Low family risk, DRD4 s alleles	0.011	0.218	0.051	.959	−0.099	0.084	−1.174	.242
High family risk, DRD4 s alleles	0.141	0.191	0.739	.461	−0.005	0.099	−0.048	.961
Low family risk, DRD4 l alleles	0.283	0.281	1.004	.316	0.143	0.114	1.257	.210
High family risk, DRD4 l alleles	−0.821	0.321	−2.559	.011	−0.335	0.168	−1.991	.047

Note. Low family risk: 1 SD below the mean; high family risk: 1 SD above the mean.
