Primary Outcome Measures:
  • Change From Baseline in Drinking Quantity and Frequency Using Drinks Per Week at Week 12 [ Time Frame: Baseline and Week 12 ]
    Standard drinks are equivalent to 14 grams of pure alcohol and number of drinks are assessed with Timeline Follow-Back (TLFB) methods. Change = (Week 12 - Baseline). More negative values indicate less use of alcohol.

  • Change From Baseline in Drinking Quantity and Frequency Using Drinking Days Per Week at Week 12 [ Time Frame: Baseline and Week 12 ]
    Standard drinks are equivalent to 14 grams of pure alcohol and number of drinks are assessed with Timeline Follow-Back (TLFB) methods. A drinking day is a day where any alcohol is consumed. Change = (Week 12 - Baseline). More negative values indicate less use of alcohol.
