Notes: Percentage heavy drinking days, drinks per drinking day, and percentage days abstinent were computed using the most recent 30 days of drinking of the 90-day prebaseline assessment window and then again for each consecutive 4-week period. Heavy drinking: four or more drinks per day for women and five or more drinks per day for men. SF-12 = Short Form-12; WHOQOL = World Health Organization Quality of Life.
