Proportion of variance explained in past month substance use by domain

Models	Cigarette Smoking	Binge Drinking	Marijuana Use	Polysubstance Use
Domain-specific
Neighborhood Structural (census)	.24	.17	.23	.24
Neighborhood Experience	.31	.25	.31	.33
School	.27	.35	.43	.34
Peer	.33	.51	.40	.40
Family	.31	.20	.30	.29
All Domains	.41	.58	.48	.45

Notes. Maximum proportion = 1; each domain-specific model included general and substance use-specific factors for that domain only, sociodemographic factors, and early initiation of substance use; all domain models included all covariates simultaneously.
