Abstract
A 2×2 randomized, factorial pretest/posttest group design was used to evaluate the effectiveness of self-help smoking cessation methods at the worksite. The study investigated the effect of a multicomponent health education and skill intervention versus the effect of a monetary incentive to the employee for quitting. All employees received, in addition, a standardized self-help smoking cessation manual and maintenance manual. Following agreement to participate and a baseline smoking history, all participants were followed for 6 weeks, 6 months, and 12 months. Saliva was obtained for thiocyanate (SCN) analysis of smoking status. Of the estimated 2000 smokers at the site, 387 smokers were recruited. Employees were randomly assigned to one of four groups. Results of this random trial indicate that those employees receiving a multicomponent program were most successful in quitting and remaining abstinent. The monetary incentive appears to have no effect on quit rate.
