Abstract

BACKGROUND: We examined the effects of baseline drug use and dependence on alcohol use outcomes following brief motivational intervention for at-risk drinking (BMI-ETOH). METHODS: HLM models were developed to test the interaction of drug use and dependence with BMI-ETOH for alcohol use among Hispanic (n=539), Caucasian (n=667), and Black (n=287) patients admitted to a Level-1 trauma center who screened positive for alcohol misuse. RESULTS: Analyses of an interaction of drug dependence and BMI-ETOH at baseline showed significant positive effects among Hispanics but not Caucasians or Blacks at six- and 12-months for percent days abstinent (6-month: B=0.27, SE=0.10, p=0.006; 12-month: B=0.41, SE=0.11, p<0.001), volume per week (6-month: B=-1.91, SE=0.77, p=0.01; 12-month: B=-2.71, SE=0.86, p=0.002), and maximum amount consumed (6-month: B=-1.08, SE=0.46, p=0.02; 12-month: B=-1.62, SE=0.52, p=0.002). CONCLUSIONS: Baseline drug dependence did not negatively impact drinking outcomes. Among Hispanics, those with drug dependence at baseline who received a BMI-ETOH demonstrated consistent improvements across drinking outcomes. While the effects of drug use at baseline on drinking outcomes following BMI-ETOH varied by type of drug used and ethnicity, additional research is required.
