In this research note, we carried out a 2󫎾 experimental design to investigate the impact of the design of the privacy and confidentiality assurances on the respondents’ probability to participate in or break off the Web survey. In these experiments, we examined the effect of (1) emphasizing the privacy rights in the e-mail invitation, (2) placing the privacy rights in bold on the welcome screen, and (3) having a checkbox in which the respondents have to indicate that they have read and agreed to these assurances. We expected that the more these rights were emphasized, the less likely the respondents were to complete the survey. However, the way these assurances are presented in the e-mail invitation or on the welcome screen has no significant influence on the response rate.
