Bivariate negative binomial regression analyses predicting cigarette, marijuana, and alcohol use.

		Outcome
		Cigarette Use		Marijuana Use		Alcohol Use
Level	Predictor	b (SE)	e^b	b (SE)	e^b	b (SE)	e^b
Within	Outness	.18 (.20)	1.20	.48 (.28)	1.62	−.23 (.51)	.79
Between	Outness	−.65 (.18)^**	.52	−.05 (.04)	.95	1.20 (.26)^**	3.32
	Sexual Orientation	.04 (.28)	1.04	−.12 (0.31)	.89	.09 (.27)	1.09
	Gender	.10 (.30)	1.11	−.21 (.01)^**	.81	−.30 (.23)	.74

Notes. Separate models were tested for each outcome variable. e^b represents the rate parameter (multiplicative increase in outcome associated with a one unit increase in the predictor). Outness is measured at 18 and 48 months, and cigarette, marijuana, and alcohol use are measured at 24 and 60 months. Gender is coded as male = 0 and female = 1. Sexual orientation is coded as gay/lesbian = 0 and bisexual = 1.
