Subjects were randomized to intervention or control groups. Intervention aimed to reduce alcohol intake to no more than 14 drinks per week and 50 percent or less of each participant's baseline level. The intervention technique consisted of a cognitive-behavioral program, the intensive phase of which consisted of six counseling sessions over three months. Echocardiograms were obtained at baseline and six months after randomization. Biochemical markers were used to validate changes in alcohol consumption. The trial included an eighteen-month feasibility phase with six-month follow-up and a 36-month main trial with two years of follow-up. Recruitment for the full-scale trial ended in June 1993. Final study visits were conducted in September and October 1994.
