Predictors of smoking cessation in an incentive-based community intervention.

The Quit and Win Challenge, an incentive-based intervention, was implemented in two counties in Eastern Ontario to encourage adult smokers to quit smoking. Participants (n = 231) were compared with adult smokers selected at random (n = 385) from a larger, four-county area. Baseline characteristics were assessed by telephone interview, including socio-demographic and smoking-related factors. Follow-up interviews were also conducted by telephone. Initial and follow-up response rates were high (over 84%) in both groups. Compared with the random survey group, Quit and Win participants tended to be younger, more educated, employed and heavier smokers, with fewer friends or co-workers who smoked. After one year, 19.5% of them reported that they were smoke-free, whereas less than 1% of the random group had achieved cessation. This translates into an impact rate of 0.17%, affecting 1 in 588 adult smokers. With the exception of the smokers' baseline "stage of change," none of the socio-demographic or smoking factors was predictive of cessation. We conclude that this intervention achieved only limited success and attracted certain sectors of the community disproportionately, i.e. smokers who were highly motivated to quit. We argue that increased access to proven cessation therapies would improve the impact of such interventions.

The use and impact of incentives in population-based smoking cessation programs: a review.

PURPOSE: This review discusses current published literature on population-based smoking cessation interventions that involve incentives and examines whether such interventions are effective in reducing the prevalence of smoking. SEARCH METHOD: Studies published between 1975 and Spring 1997 were identified through a computerized search of four electronic databases (MEDLINE, HEALTH, CINAHL, and PSYCINFO) and reference lists of key articles using the following key words: (smoking cessation OR quit smoking) AND (contest OR competition OR incentive OR lottery OR quit and win). This search yielded 79 articles. To be included, studies had to be published in English and had to have presented either quit rates or participation rates for an incentive-based program that used population-based recruitment. Of the 79 articles, 17 met these criteria. FINDINGS: Population-based interventions generally attract 1 to 2% of the target population, but these participation rates can potentially be increased through the use of innovative recruitment techniques. No specific type of recruitment strategy was shown to be consistently more effective than others. There is no evidence that particular types of incentives are able to influence participation or quit rates, but the size of an incentive does appear to be important, with larger incentives viewed as more effectively motivating smokers to quit and stay smoke free than smaller ones. Estimates of the cost per quitter have ranged from less than $20 to over $400. There are some indications that the costs of such programs compare favorably with smoking cessation classes or clinic-based approaches. CONCLUSION: Incentive-based smoking cessation programs that target an entire community have the advantage of reaching a large and diverse group of smokers. They may, however, attract only smokers who are already motivated to quit. Realistically, incentive-based programs aimed at the general population can expect 1% of all their smokers to quit smoking. Quit rates among participants may initially be high (i.e., mean quit rate of 34% at 1-month follow-up) but decrease over time (i.e., mean rate of 23% at 1 year). The results of this review suggest a continued need to establish standard and valid criteria for the evaluation of smoking cessation interventions. Methodological differences among existing studies make them difficult to compare and interpret.

Staging of adult smokers according to the transtheoretical model of behavioural change: analysis of an eastern Ontario cohort.

OBJECTIVES: 1) To describe the distribution of adult smokers in an existing cohort according to stages of change theory; and 2) to compare movements of these smokers through the stages of change. DESIGN: Secondary analysis of existing cohort data. SETTING: Eastern Ontario. PARTICIPANTS: Adult smokers who: 1) enrolled in a Quit & Win Challenge, or 2) received smoking cessation information (Quit Kit) from their area health unit, or 3) were randomly selected by telephone survey. RESULTS: 706 smokers were recruited and followed for one year. Only 2% of the adult smokers selected by random telephone survey were in the "action" stage at baseline, compared with 14% of the Quit and Win Challenge participants, and 14% of the Quit Kit recipients. Variations in movement through the stages of change were observed between groups upon follow-up. CONCLUSIONS: The results suggest a need to use stage-matched approaches when developing population-based smoking cessation interventions.
