Heavy drinking days, % | |||||
Baseline (past 90 days) | 91.7 (9.6) | 86.8 (14.8) | 90.4 (18.9) | 92.4 (17.0) | n.s. |
Pre-scan | 5.4 (6.4) | 13.3 (16.5) | 2.2 (3.5) | 1.2 (2.9) | Lower AW > Higher, p = .001 |
Post-scan* | 10.6 (19.7) | 23.1 (25.5) | 8.4 (13.0) | 4.6 (9.7) | Lower AW > Higher, p = .04 |
All figures except Ns are means (standard deviations). Pre- and post-scan drinking data represent the percentage of heavy drinking days for each subject before vs. after that subject’s scan. ADS, Alcohol Dependence Scale; OCDS, Obsessive Compulsive Drinking Scale; n.s., not significant.
Excludes participants who dropped out after the scan (N = 5; 1 from low AW/placebo group, 3 from low AW/GBP/FMZ group, and 1 from higher AW/GBP/FMZ group).
