The authors compared the effect of a behavioral multicomponent smoking cessation special intervention (SI) to an advice-only intervention (AO) on smoking status at 5 years for smokers with coronary disease (n = 160). Regression analyses revealed an interaction between intervention type and disease severity such that patients in the SI group with greater degrees of coronary artery disease showed significantly higher cessation rates (odds ratio = 344 for 3-vessel disease in the SI vs. AO, p = .01). Factors predicting maintained abstinence included having 12 or more years of education, contemplating quitting smoking or being ready to begin action to quit at baseline, and having a higher self-efficacy score.
