- Percentage of Heavy Drinking Days During the Last 8 Weeks of Treatment [ Time Frame: weeks 9-12 ]The percentage of days of heavy drinking will be examined over the final 8 weeks of the study averaged by month (weeks 9-12 and weeks 13-16). A heavy drinking day is defined as 5 or more standard drinks for men and 4 or more standard drinks for women. A standard drink contains approximately 0.6 fluid ounces of pure alcohol.
- Percentage of Heavy Drinking Days During the Last 8 Weeks of Treatment [ Time Frame: weeks 13-16 ]The percentage of days of heavy drinking will be examined over the final 8 weeks of the study averaged by month (weeks 9-12 and weeks 13-16). A heavy drinking day is defined as 5 or more standard drinks for men and 4 or more standard drinks for women. A standard drink contains approximately 0.6 fluid ounces of pure alcohol.
- Percentage of Heavy Drinking Days During the Last 8 Weeks of Treatment [ Time Frame: 8 weeks ]The percentage of days of heavy drinking will be examined over the final 8 weeks of the study. A heavy drinking day is defined as 5 or more standard drinks for men and 4 or more standard drinks for women. A standard drink contains approximately 0.6 fluid ounces of pure alcohol. Presented here is the average of the 8 weeks (reported as week 17 originally).
- Smoking Abstinence [ Time Frame: Weeks 13-16 ]Smoking abstinence is defined by self-reported abstinence from smoking for the last four weeks of treatment (weeks 13-16) and a urine cotinine level less than 15ng/mL measured at week 17.
- Drinking Related Consequences [ Time Frame: End of treatment (Week 17) ]A self-report measure of negative consequences from drinking will be administered and the total score are analyzed. The ImBIBe, a measure of alcohol consequences based on the Drinker Inventory of Consequences (DRINC) was used. The DRINC total score has a range from 0-45, 45 being the highest score (or greatest number of negative consequences).
