Standardized Hierarchical Regression Analyses for Past-Month Alcohol Use and Binge Drinking

Predictors	Alcohol Use						Binge Drinking
	Model 1			Model 2			Model 1			Model 2
	β	SE		β	SE		β	SE		β	SE
Peer Variables
Alcohol use	.27^***	.05		.26^***	.05		.23^***	.05		.22^***	.06
Offers to use	.40^***	.05		.39^***	.05		.30^***	.05		.28^***	.05
Parent Variables
Rules against use				−.11^**	.04					−.10^*	.05
Family support				.03	.04					.02	.04
R²			.46			.48			.34			.35
ΔR²			.33			.01			.20			.01
ΔF			112.79****			4.40^*			55.63^***			3.01^*

Note. N = 383. ΔR² for each Model 1 represents variance explained after adjusting for age, gender, ethnic-racial group, academic performance, enrollment in school, living arrangement, and assignment to study arm. Rules against use (0 = no, 1 = yes); lower family support scores are better.
