Abstract
OBJECTIVES: Our study examined the effect of a ChinaYuan (CNY) 10 cash incentive on the participation rate in a face-to-face health survey among the general Chinese population. STUDY DESIGN AND SETTING: Subjects older than 15 years of age and had been living in the two selected districts for more than 6 months were selected using multistage random sampling. Participants from only one district received a cash incentive (CNY 10) for completing the survey. RESULTS: The participation rates in the nonincentive and incentive groups were 39.9% and 61.2%, respectively, P < 0.01. In the nonincentive group, the 65-74 years age group had the highest participation rate (54.4%); no significant difference was found between men (39.4%) and women (40.5%), P = 0.59. In the incentive group, the highest participation rate was observed in the ≥75 years (78.1%) age group. The cost for a completed interview was CNY 34.5 in the incentive group and CNY 35.8 in the nonincentive group. CONCLUSION: Cash incentives might increase participation rates in face-to-face surveys in China. The absolute cost was higher for the incentive group, whereas cost for a completed interview was actually the lowest. Furthermore, participation rate did not differ between men and women, but elders were more likely to participate in health surveys.
