Monetary incentives can increase response rate in patient surveys, but calibration of the optimal incentive level is required. Our aim was to assess the effect of different monetary incentives on response rates to calibrate the optimal monetary incentive for ambulatory patients.
A patient-randomized trial was performed in which targeted individuals received different gift vouchers (€5.00, €7.50, €10.00, and €12.50) on completion of a survey and interview. Eligible patients (diagnosed type 2 diabetes, over 18 years) were recruited from primary care practices.
The response rate for the €12.50 incentive was lower compared with both the €7.50 and the €10.00 incentive [odds ratio (OR) = 0.60 and OR = 0.58]. A nonlinear model yield a better fit than a linear model. Within the observed range of incentive levels, an overall decrease in response rate was found.
High monetary incentives are not only inefficient but also less effective.
金钱激励可以提高患者调查中的回应率，但需要校准最佳激励水平。我们的目的是评估不同金钱激励对回应率的影响，以校准门诊患者的最佳金钱激励。
进行了一项患者随机试验，目标个体在完成调查和访谈后会收到不同金额的礼品券（5.00欧元、7.50欧元、10.00欧元和12.50欧元）。符合条件的患者（诊断为2型糖尿病，年龄超过18岁）从初级保健机构招募。
与7.50欧元和10.00欧元的激励相比，12.50欧元激励的回应率较低[优势比（OR）=0.60和OR = 0.58]。非线性模型比线性模型拟合得更好。在观察到的激励水平范围内，发现回应率总体下降。
高额金钱激励不仅效率低下，而且效果较差。
