Poisson regression results for Time 1 variables predicting Time 2 drinking and driving

Variable	Drinking and driving	Riding w/ drinking driver
Drinking and driving/riding with a drinking driver	.21*	.66†
Alcohol use	.25*	.67
Male gender	.31†	.72
Age	.22	.70
Normative beliefs	.23	.97†
Attitudes	.48†	.62
Perceived consequences	.21	.57

Notes: Values are predicted rate of increase in frequency from Poisson regression. For drinking and driving, n = 162. For riding with a drinking driver, n = 202.
