Personal financial incentives can change habitual health-related behaviors and help reduce health inequalities .
However , their role in reducing disease burden is potentially limited given current evidence that effects dissipate beyond three months post-incentive removal
OBJECTIVES Uncertainty remains about whether personal financial incentives could achieve sustained changes in health-related behaviors that would reduce the fast-growing global non-communicable disease burden .
This review aims to estimate whether : i. financial incentives achieve sustained changes in smoking , eating , alcohol consumption and physical activity ; ii .
effectiveness is modified by ( a ) the target behavior , ( b ) incentive value and attainment certainty , ( c ) recipients ' deprivation level .
The effects of cash and lottery incentives on mailed surveys to physicians: a randomized trial.
Low response rates , especially among physicians , are a common problem in mailed survey research . We conducted a r and omized trial to examine the effects of cash and lottery incentives on response rates .  A total of 4,850 subjects were r and omized to one of three interventions accompanying a mailed survey-no incentive ( n = 1,700 ) , cash payment [ three levels of Hong Kong dollars ( HKD ) $ 10 , $ 20 , and $ 40 ; N = 50 in each subgroup ] , or entry into a lottery ( three levels of HKD$1,000 , $ 2,000 , and $ 4,000 ; N = 1,000 in each subgroup ) on receipt of the completed question naire . The response rates were higher among those offered incentives than those without ( 19.8 % vs. 16.8 % , P = .012 ) . Cash was the more effective incentive compared to lottery ( 27.3 % vs. 19.4 % , P = .017 ) . Response also increased substantially between the first and second mailings ( 14.2 % vs. 18.8 % , P > .001 ) . In addition , those with specialist qualifications were more willing to participate in mailed surveys . We found no significant differences in response outcomes among the various incentive arms . Cash reward at the $ 20 level was the most cost-effective intervention , in terms of cost per responder . Further systematic examination of the effects of different incentive strategies in epidemiologic studies should be encouraged
