Incentives in the sexual health survey

2017

-

During the data collection process of the “Sexual health and behavior of young people in Switzerland” survey conducted in 2017, an unconditional incentive (a pen) was given to a part of the sample. A reminder letter was also sent to another part of the sample. Overall, n=49’798 people aged 24-26 were contacted to participate in the survey, but only 5’618 answered the questionnaire in full. In this project, we analyze the effect of both measures on the response rate.

A pen unconditionally given with the invitation letter led to a significantly higher response rate. However, this effect did not persist in the long term, after the reminder was sent.
