It is well established that providing incentives (e.g., monetary incentive) can boost the participation rate of a survey or a campaign (e.g., asking citizens to measure and report the rainfall intensity using their smartphone). I am interested in how will the response rate change if we provide different level of incentives.
If we draw a figure with the x-axis as the level of incentive, and the y-axis as the participation rate, how will this line looks like? Will it be a line with diminishing margin (e.g., like a log function), or it will be a 'S' line?
I will be so grateful if anyone could provide some research on this issue.
I do not have answers, but I think it actually depends on the context. I conducted a research in some Latin American countries, for example, in which people were very suspicious because incentives were provided.
Thank you Dr. Vannini, for your response. My plan is that nowadays it is possible that people use their personal smartphones to measure and report the rainfall intensity (see my recent paper about this issue: Article Gauging Through the Crowd: A Crowd-Sourcing Approach to Urba...
), and we can possibly boost the participation rate by providing some incentives.The possible relationship between the amount of incentive and the participation rate could be very helpful for me to design the way we distribute the incentives.
Offering incentives for a survey respondent’s time is one way to increase customer survey response rates. Some people feel a sense of civic duty when approached with a survey, and it is enough motivation for them to know their input will be used to help others. However, the use of a monetary or gift incentive has been proven to significantly increase response rates in many customer surveys.
