Note. All participants received a brief advice session that at baseline. Those who continued to drink to risky levels and experienced alcohol related problems (higher risk drinkers) were randomized to either the BMI or AO condition following the 6 week assessment. BMI assessments occurred between 6 week and 3 month assessments. All participants (lower and higher risk drinkers) completed the 3 and 9 month follow-ups. Means that do not share subscripts differ at p < .05.
