Hierarchical Multiple Regression Predicting Baseline Drinking Episodes From Perceived Pledge Class Drinking Norms and House Attitudes

Variable	Baseline drinking
	β	$R_{\text{change}}^2$	$R_{\text{total}}^2$
1. Group assignment	−.04	.14***	.14***
Gender (G)	−.37***
2. Perceived pledge class drinking norm (DNRF)	.40***	.14***	.28***
3. House acceptability of drinking (HAQ)	.06	.00	.28***
4. G × DNRF	−.01	.00	.28***
G × HAQ	−.06	.00	.28***

Note. N = 571. Variables were entered in five steps in the order listed. Gender: male = 0, female = 1. Group assignment: control condition house = 0, intervention condition house = 1. β = standardized regression weights; DNRF = perceived pledge class drinking norm based on the Drinking Norms Rating Form; HAQ = House Acceptability Questionnaire.
