This study evaluated the impact of a year-long incentives-based worksite smoking-cessation program. Nineteen moderate-sized worksites, employing a total of approximately 1100 smokers, were randomized to Incentive or No Incentive conditions. All identified smokers in the worksite were considered as subjects, whether or not they participated in the intervention. Analyses were conducted at both the worksite and individual level, and using both self-reported and biochemically validated cessation as endpoints. The incentive program did not significantly improve cessation rates at either the 1-year or 2-year follow-up assessments. We conclude that more broadly focused interventions that also address worksite smoking policies, skills training, and cessation resources, or programs that target additional risk factors are needed to substantially enhance quit rates. This study examined the effect of program format and incentives on participation and cessation in worksite smoking cessation programs.
                Twenty-four worksites were randomized to 6 conditions that differed in cessation program format and the use of incentives. Programs were offered for 18 months in each worksite. A total of 2402 cigarette smokers identified at baseline were surveyed 12 and 24 months later to assess participation in programs and cessation.
                A total of 407 (16.9%) of the smoker cohort registered for programs; on the 12- and 24-month surveys, 15.4% and 19.4% of the cohort, respectively, reported that they had not smoked in the previous 7 days. Registration for programs in incentive sites was almost double that of no-incentive sites (22.4% vs 11.9%), but increased registration did not translate into significantly greater cessation rates. Program type did not affect registration or cessation rates.
                Although incentives increase rates of registration in worksite smoking cessation programs, they do not appear to increase cessation rates. Phone counseling seems to be at least as effective as group programs for promoting smoking cessation in worksites. Smoking causes chronic obstructive pulmonary disease (COPD), but few controlled studies have tested anti-smoking treatments in COPD. With procedures likely to attract unmotivated persons we recruited 49 quite-ill, smoking COPD patients. During one or two daily home visits for 85 days, breath carbon monoxide (CO) and self-reports of daily smoking were obtained. Patients, given quit dates and nicotine gum (2-mg pieces, up to 30 per day), were assigned randomly to three groups: Experimentals were reinforced with lottery tickets for CO < 10 ppm. Cigarette Self Report (CSR) patients were reinforced for reporting no smoking that day. Controls received non-contingent payments. Each group's mean CO level fell at the quit date. Thereafter, reinforced patients maintained significantly lower CO levels than Controls. Although many more 24-h abstentions occurred in the intervention period than in baseline, few patients sustained abstinence; the groups did not differ in that regard. Outcome was predicted by decisions to throw away cigarettes when intervention began, but not by motivation scales nor Fagerstrom dependence scores. Pay schedules apparently exaggerated self-reports of reduced smoking. Although results are statistically significant, there is still no proven, practical treatment for smoking in advanced COPD. A 2 x 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. This study reports an efficacy trial of four work-site health promotion programs. It was predicted that strategies making use of behavioral counseling would produce a greater reduction in cardiovascular disease risk factors than screening and educational strategies.
                Twenty-eight work sites were randomly allocated to a health risk assessment, risk factor education, behavioral counseling, or behavioral counseling plus incentives intervention. Participants were assessed before the intervention and at 3, 6, and 12 months.
                Compared with the average of the health risk assessment and risk factor education conditions, there were significantly higher validated continuous smoking cessation rates and smaller increases in body mass index and estimated percentage of body fat in the two behavioral counseling conditions. The behavioral counseling condition was associated with a greater reduction in mean blood pressure than was the behavioral counseling plus incentives condition. On average among all groups, there was a short-term increase in aerobic capacity followed by a return to baseline levels.
                Work-site interventions that use behavioral approaches can produce lasting changes in some cardiovascular risk factors and, if implemented routinely, can have a significant public health impact. nan nan Worksite competitions have shown promise in facilitating smoking cessation among employees, but the effectiveness of the competition component itself has not been determined. A multicomponent behavioral treatment and maintenance program plus nicotine gum were provided to competition and no-competition conditions at two large worksites. At 1-year follow-up, 100% of subjects were contacted and measurement of expired carbon monoxide validated abstinence. Recruitment rates were significantly higher in the competition group (2% of smokers) than the no-competition group (0.6% of smokers, P less than 0.001). One-year abstinence rates were 50% for the competition group and 25% for the no-competition group. This difference was not statistically significant (P less than 0.25). However, survival analysis revealed a significant difference in number of weeks abstinent during the year after treatment. Mean weeks abstinent was 35 for competition and 22 for no-competition (P less than 0.05). At the 3-month follow-up, the number of boxes of nicotine gum used predicted abstinence (P less than 0.002). At the 1-year follow-up, rated supportiveness of one's "buddy" (P less than 0.01) and number of sick days prior to starting the program predicted abstinence (P less than 0.003). It is suggested that competition, nicotine gum, and social support may enhance worksite smoking cessation program rates. This study examined the relative contribution of contingent payment and worksite CO monitoring to the long-term maintenance of smoking abstinence. Forty-seven hospital employees who had abstained from smoking for five days (confirmed by CO analysis) were randomly assigned to one of three follow-up groups: (a) contingent payment/frequent monitoring (n = 17); (b) noncontingent payment/frequent monitoring (n = 16); or (c) non-contingent payment/infrequent monitoring (n = 14). Contingent payment combined with frequent CO monitoring delayed but did not ultimately prevent subjects relapse to smoking by the end of the six month follow-up. Contingent subjects maintained CO values less than or equal to 11 ppm significantly longer than did either the Non-contingent or the Control subjects (p = .03). CO monitoring alone had no effect on abstinence outcomes; both Noncontingent and Control subjects showed high rates of early relapse. Smoking is the leading preventable cause of premature death in the United States. Previous studies of financial incentives for smoking cessation in work settings have not shown that such incentives have significant effects on cessation rates, but these studies have had limited power, and the incentives used may have been insufficient.
                We randomly assigned 878 employees of a multinational company based in the United States to receive information about smoking-cessation programs (442 employees) or to receive information about programs plus financial incentives (436 employees). The financial incentives were $100 for completion of a smoking-cessation program, $250 for cessation of smoking within 6 months after study enrollment, as confirmed by a biochemical test, and $400 for abstinence for an additional 6 months after the initial cessation, as confirmed by a biochemical test. Individual participants were stratified according to work site, heavy or nonheavy smoking, and income. The primary end point was smoking cessation 9 or 12 months after enrollment, depending on whether initial cessation was reported at 3 or 6 months. Secondary end points were smoking cessation within the first 6 months after enrollment and rates of participation in and completion of smoking-cessation programs.
                The incentive group had significantly higher rates of smoking cessation than did the information-only group 9 or 12 months after enrollment (14.7% vs. 5.0%, P<0.001) and 15 or 18 months after enrollment (9.4% vs. 3.6%, P<0.001). Incentive-group participants also had significantly higher rates of enrollment in a smoking-cessation program (15.4% vs. 5.4%, P<0.001), completion of a smoking-cessation program (10.8% vs. 2.5%, P<0.001), and smoking cessation within the first 6 months after enrollment (20.9% vs. 11.8%, P<0.001).
                In this study of employees of one large company, financial incentives for smoking cessation significantly increased the rates of smoking cessation. (ClinicalTrials.gov number, NCT00128375.)
                2009 Massachusetts Medical Society To evaluate relapse prevention (relapse prevention) and contingency management (contingency management) for optimizing smoking cessation outcomes using nicotine replacement therapy for methadone-maintained tobacco smokers.
                Experimental, 2 (relapse prevention)x2 (contingency management) repeated measures design using a platform of nicotine replacement therapy featuring a 2-week baseline period, followed by randomization to 12 weeks of treatment, and 6- and 12-month follow-up visits.
                Three narcotic treatment centers in Los Angeles.
                One hundred and seventy-five participants who met all inclusion and no exclusion criteria.
                Participants received 12 weeks of nicotine replacement therapy and assignment to one of four conditions: patch-only, relapse prevention + patch, contingency management + patch and relapse prevention + contingency management + patch.
                Thrice weekly samples of breath (analyzed for carbon monoxide) and urine (analyzed for metabolites of opiates and cocaine) and weekly self-reported numbers of cigarettes smoked.
                Participants (73.1%) completed 12 weeks of treatment. During treatment, those assigned to receive contingency management showed statistically higher rates of smoking abstinence than those not assigned to receive contingencies (F3,4680=6.3, P=0.0003), with no similar effect observed for relapse prevention. At follow-up evaluations, there were no significant differences between conditions. Participants provided more opiate and cocaine-free urines during weeks when they met criteria for smoking abstinence than during weeks when they did not meet these criteria (F1,2054=14.38, P=0.0002; F1,2419=16.52, P<0.0001).
                Contingency management optimized outcomes using nicotine replacement therapy for reducing cigarette smoking during treatment for opiate dependence, although long-term effects are not generally maintained. Findings document strong associations between reductions in cigarette smoking and reductions in illicit substance use during treatment. We evaluated the effectiveness of a worksite smoking cessation/reduction program both with and without formal competition for monetary prizes in five worksites (n = 107). A greater percentage of eligible smokers participated in the competition (88 per cent) than the non-competition (53 per cent) condition. Treatment outcome among participants was generally equivalent across conditions, but at a six-month follow-up, nonabstinent subjects in the competition condition had lower levels of carbon monoxide than subjects in the non-competition condition. On a worksite-wide basis, a higher percentage of employees quit smoking in the competition condition (16 per cent) compared to the non-competition (7 per cent). Adults with any DSM-IV diagnosed mental illness smoke nearly half of the cigarettes consumed in the U.S. (Lasser et al. 2000). This study compared two smoking cessation interventions for persons with schizophrenia or other serious mental illness because national data suggests that: (1) they smoke at two to three times the rate of the general population; (2) cessation interventions for this population are understudied; (3) most cessation studies exclude persons with serious mental illness; and (4) cessation results in public health care savings and disposable income savings for clients. This study included a large number of persons with serious mental illness (N=181) who were randomly assigned to one of three groups: contingent reinforcement (CR), CR plus nicotine patch (21 mg, CR+NRT) for 16 weeks, and a minimal intervention, self-quit control group. These participants were followed for 36 weeks. CR was accomplished with escalating financial compensation for achieving and maintaining abstinence as verified by expired carbon monoxide (CO). Quit rates, as measured by expired CO, were higher and discordant with saliva cotinine quit rates. Cotinine showed lower quit rates and small differences between intervention and control participants at weeks 20 and 36. There was, however, evidence of reduced smoking and importantly, no evidence of psychiatric exacerbation. The efficacy of contingency-management (CM) and motivational enhancement therapy (MET) for college student smoking cessation was examined.
                Nontreatment-seeking daily smokers (N = 110) were randomly assigned to 3 weeks of CM versus noncontingent reinforcement (NR) and to three individual sessions of MET versus a relaxation control in a 2 x 2 experimental design. Expired carbon monoxide (CO) samples were collected twice daily for 3 weeks. Participants earned 5 US dollars for providing each sample; additionally, those randomized to CM earned escalating monetary rewards based on CO reductions (Week 1) and smoking abstinence (Weeks 2-3).
                Compared with NR, CM resulted in significantly lower CO levels and greater total and consecutive abstinence during the intervention. Those in the CM and MET groups reported greater interest in quitting smoking posttreatment, but rates of confirmed abstinence at follow-up were very low (4% at 6-month follow-up) and did not differ by group.
                Findings support the short-term efficacy of CM for reducing smoking among college students. Future research should explore enhancements to CM in this population, including a longer intervention period and the recruitment of smokers who are motivated to quit.
With the exception of one recent trial, incentives and competitions have not been shown to enhance long-term cessation rates. Early success tended to dissipate when the rewards were no longer offered. Rewarding participation and compliance in contests and cessation programmes may have potential to deliver higher absolute numbers of quitters. The one trial that achieved sustained success rates beyond the reward schedule concentrated its resources into substantial cash payments for abstinence rather than into running its own smoking cessation programme. Such an approach may only be feasible where independently-funded smoking cessation programmes are already available. Future research might explore the scale and longevity of possible cash reward schedules, within a variety of smoking populations.
