Objectives. This study examined the effect of program formatand incentives on participation and cessation in worksite smokingcessation programs.
Methods. Twenty-four worksites were randomized to 6 conditionsthat differed in cessation program format and the use of incentives.Programs were offered for 18 months in each worksite. A totalof 2402 cigarette smokers identified at baseline were surveyed12 and 24 months later to assess participation in programs andcessation.
Results. A total of 407 (16.9%) of the smoker cohort registeredfor programs; on the 12- and 24-month surveys, 15.4% and 19.4%of the cohort, respectively, reported that they had not smokedin the previous 7 days. Registration for programs in incentivesites was almost double that of no-incentive sites (22.4% vs11.9%), but increased registration did not translate into significantlygreater cessation rates. Program type did not affect registrationor cessation rates.
Conclusions. Although incentives increase rates of registrationin worksite smoking cessation programs, they do not appear toincrease cessation rates. Phone counseling seems to be at leastas effective as group programs for promoting smoking cessationin worksites.
