Table 2. Parameters of linear regression models for desire to quit smoking, aversion to smoking, and quit efficacy with warning and efficacy as predictors.

	Dependent Variable
Predictor	Desire to Quit Smoking (Dq)			Aversion to Smoking (−Ds)			Quit Efficacy (Eq)
	B	SE	Prob	B	SE	Prob	B	SE	Prob
Gender	.009	.034	.795	.085	.026	.001	−.078	.026	.002
Age Group	.147	.035	<.001	.105	.027	<.001	−.213	.027	<.001
Warning (α)	.026	.019	.174	.069	.015	<.001	−.002	.016	.915
Efficacy (Eq)	−.180	.018	<.001	.025	.014	.076
Efficacy2 (Eq 2)	−.024	.016	.139	−.002	.012	.887
Smoke Frequency (β)	−.118	.037	.002	−.439	.029	<.001	−.617	.027	<.001

Note: Males were coded as 0 and females as 1; Age was coded as 0 for 18–24 and 1 for 25+; Smoke frequency was coded 1 for daily smokers and 0 for less often. B is the unstandardized coefficient, SE is the standard error, and Prob is the probability of null hypothesis.
