Our primary conclusion is that there is a lack of compelling evidence that incentives of any form represent a compelling NCD reduction strategy .
The rising epidemic of non-communicable diseases ( NCDs ) poses substantial health and economic challenges to both individuals and society .
Application of incentive-based strategies based on traditional and behavioural economic theory has emerged as a potential strategy to address rising rates of NCDs .
Yet , whether or not incentives truly represent a promising strategy for addressing NCDs has not been systematic ally addressed nor is it clear whether certain behavioural economic strategies outperform others or simply offering a cash-based incentive for meeting a goal .
In this systematic review we aim to determine whether there is an evidence base for any of these strategies .
Randomized trial of four financial-incentive programs for smoking cessation.
BACKGROUND Financial incentives promote many health behaviors , but effective ways to deliver health incentives remain uncertain . METHODS We r and omly assigned CVS Caremark employees and their relatives and friends to one of four incentive programs or to usual care for smoking cessation . Two of the incentive programs  targeted individuals , and two targeted groups of six participants . One of the individual-oriented programs and one of the group-oriented programs entailed rewards of approximately $ 800 for smoking cessation ; the others entailed refundable deposits of $ 150 plus $ 650 in reward payments for successful participants . Usual care included informational re sources and free smoking-cessation aids . RESULTS Overall , 2538 participants were enrolled . Of those assigned to reward-based programs , 90.0 % accepted the assignment , as compared with 13.7 % of those assigned to deposit-based programs ( P<0.001 ) . In intention-to-treat analyses , rates of sustained abstinence from smoking through 6 months were higher with each of the four incentive programs ( range , 9.4 to 16.0 % ) than with usual care ( 6.0 % ) ( P<0.05 for all comparisons ) ; the superiority of reward-based programs was sustained through 12 months . Group-oriented and individual-oriented programs were associated with similar 6-month abstinence rates ( 13.7 % and 12.1 % , respectively ; P=0.29 ) . Reward-based programs were associated with higher abstinence rates than deposit-based programs ( 15.7 % vs. 10.2 % , P<0.001 ) . However , in instrumental-variable analyses that accounted for differential acceptance , the rate of abstinence at 6 months was 13.2 percentage points ( 95 % confidence interval , 3.1 to 22.8 ) higher in the deposit-based programs than in the reward-based programs among the estimated 13.7 % of the participants who would accept participation in either type of program . CONCLUSIONS Reward-based programs were much more commonly accepted than deposit-based programs , leading to higher rates of sustained abstinence from smoking .  Group-oriented incentive programs were no more effective than individual-oriented programs .
