Summary of GEE Model Predicting Daily Volume of Alcohol Consumption From Craving in the Natural Environment and Occasion- and Person-Level Covariates

Predictor	β	95% CI	p
Daily average craving	0.34	[0.12, 0.55]	.002
Overall average craving	− 0.31	[− 0.51, − 0.11]	.002
RAPI	0.16	[0.03, 0.29]	.020
RAPI × Overall average craving	0.07	[− 0.12, 0.26]	.467
RAPI × Daily average craving	0.03	[− 0.22, 0.27]	.835
Occasion-level covariate
Weekend	0.09	[− 0.15, 0.33]	.448
Person-level covariates
Age	− 0.03	[− 0.09, 0.04]	.430
Sex (female)	− 0.16	[− 0.36, 0.04]	.119
Drinks per drinking day (Mean)^a	0.08	[− 0.01, 0.18]	.075

Note. Continuous predictors were standardized prior to entry in both models. GEE = generalized estimating equation; RAPI = Rutgers Alcohol Problem Index (higher scores indicate greater severity of alcohol-related problems); CI = confidence interval;

Derived from the 90-day Timeline Follow-Back interview conducted at baseline; coefficients represent the standardized effects of predictors on drinking outcomes (effect size d).
