Tests of mediation of behavioral strategies on drinking volume and drinking frequency

Model 1: Tests of mediation for behavioral strategies on drinking volume	B	SE B	β	Model
				Adj. R2	F
Step A: Intervention effect on behavioral strategies	2.47	1.08	0.16*	0.02	5.26*
Step B: Intervention effect on drinks per drinking day	−0.79	0.38	−0.15*	0.02	4.29*
Step C: Behavioral strategies effect on drinks per drinking day	−0.07	0.03	−0.21**	0.04	7.95**
Final step: Effect of behavioral strategies and intervention on drinks per drinking day
Behavioral strategies	−0.07	0.03	−0.19*	0.05	5.24**
Intervention	−0.63	0.40	−0.12
Model 2: Tests of mediation for behavioral strategies on drinking frequency	B	SE B	β	Model
				Adj. R2	F
Step A: Intervention effect on behavioral strategies	2.47	1.08	0.16**	0.03	5.26*
Step B: Intervention effect on number of drinking days	1.41	0.65	0.15*	0.02	4.70*
Step C: Behavioral strategies effect on number of drinking days	−0.03	0.05	−0.04	0.00	0.35
Final step: Effect of behavioral strategies and intervention on drinks per drinking day	N/A
Behavioral strategies
Intervention

Note. For intervention, 0 = CDI and 1 = BMI. N/A = Not Applicable since an earlier step in the mediational analyses was not significant. The drinks per drinking day variable was calculated by subtracting the baseline value from the 12-month value, so a positive difference score indicates an increase in the behavior. The number of drinking days variable was calculated by subtracting the baseline value from the 12-month value, so a positive difference score indicates an increase in the behavior. The behavioral strategies measure was calculated by subtracting the baseline score from the 3-month score so a positive difference score indicates an increase in use of strategies.
