This is a randomized controlled trial of 511 eligible women treated for diabetes, hypertension, infertility, or osteoporosis on an outpatient basis to test the hypothesis that those randomized to a brief intervention (BI) will drink less than those in the control condition 12 months later. A secondary goal was to identify the characteristics associated with changes in drinking outcome.
All 511 completed the initial alcohol assessment, and 96% completed the 12-month follow-up interview. Those receiving the BI also had 3- and 6-month interviews. Four outcomes were assessed: (a) mean drinks per drinking day, (b) percent drinking days, (c) binge episodes defined as four or more drinks per occasion, and (d) weeks of drinking exceeding the National Institute on Alcohol Abuse and Alcoholism sensible drinking limits.
Overall, there were no differences in drinking outcome by treatment group. Characteristics associated with changes in drinking, however, were identified to provide possible direction for future investigation.
