This article describes the results of an experiment designed to examine the impact of the use and amount of delayed unconditional incentives in a mixed mode (push to web) supplement on response rates, response mode, data quality, and sample bias. The supplement was administered to individuals who participate in the U.S. Panel Study of Income Dynamics, the longest running national household panel in the world. After 10 weeks of data collection, individuals who had not yet completed the interview were sent a final survey request and randomly assigned to one of three treatment conditions: no incentive, US$5, and US$10. The impact of the incentives on response rates and mode, effects on data quality, and sample bias are described. The implications for the use of incentives in mixed mode surveys and directions for future research are discussed.
本文描述了一项实验的结果，该实验旨在研究在混合模式（推送至网络）补充调查中使用延迟无条件激励措施及其金额对回复率、回复模式、数据质量和样本偏差的影响。该补充调查针对参与美国收入动态面板研究的个体进行，这是世界上运行时间最长的全国家庭面板研究。在收集了10周数据后，尚未完成访谈的个体收到了最终调查请求，并被随机分配到三种处理条件之一：无激励、5美元激励和10美元激励。文中描述了激励措施对回复率和回复模式的影响、对数据质量的作用以及样本偏差情况。还讨论了在混合模式调查中使用激励措施的意义以及未来研究的方向。
