Note. Italics indicate individual βs not significantly different from zero because confidence intervals (CI) contain zero. Comparisons among the three BMI conditions can be made as follows: if the midpoint of one condition falls outside of the 95% CI for another, the conditions are significantly different at p < .05. DPW = drinks per week; DDD = drinks per drinking day; HDD = heavy drinking days; pBAC = peak blood alcohol concentration; RAPI = Rutgers Alcohol Problems Inventory; BMI = brief motivational intervention; BMIe = brief motivational intervention, enhanced with decisional balance; RTCQ = Readiness-to-Change Questionnaire; INCOM = Iowa-Netherlands Comparison Orientation Measure; SSRQ = Short Self-Regulation Questionnaire; FTP = future time perspective.
