Table 3.

Multiple regressions examining the prediction of Percent Days Abstinent (criterion) by BMI+SC, F1 traits, and the BMI+SC X F1 interaction (n = 73).

	Variable	β	t	R²
Step One	BMI+SC	−.10	−.88	.01
Step Two	BMI+SC	−.12	−1.03	.01
Step Two	F1	−.17	−1.44	.03
Step Three	BMI+SC	.44	1.65	.04
	F1	.11	.64	<.01
	BMI+SC X F1	−.65^*	−2.33^*	.07^*
Model R² = .11^*

Note. BMI+SC = Brief Motivational Intervention plus Standard Care vs. SC condition. F1 = Psychopathy Checklist-Revised Factor One score. BMI+SC X F1 is a centered interaction term.
