Note. Daily BAC = Estimated Blood Alcohol Concentration for each day of self-monitoring; Avg. BAC = Average Estimated Blood Alcohol Concentration across all days of self-monitoring; SSRQ = Short Self-regulation Questionnaire; ICS = Impaired Control Scale; EIS = Eysenck Impulsiveness Scale; N RDQ = Negative Reinforcement Reasons for Drinking; Omnibus test is the overall test for all predictors in the model; incremental test is the test of all added covariates; main effect + interaction test is the test of the main effect and interaction with Daily BAC for each individual covariate.
