They are especially valuable because they allow respondents to select several responses from a list of alternatives that they consider applicable. In this study, we assessed the effectiveness of different types of instructions requesting a specific number of responses to a check-all-that-apply question in a web survey. We compared ˇ°staticˇ± instructions that are always visible together with the question stem, ˇ°dynamicˇ± instructions that instantly appear once respondents start answering the question, and ˇ°combinedˇ± instructions taking advantage of both static and dynamic instructions. Findings showed that in view of respondent compliance with the instruction, the combination of a static and dynamic instruction is most effective. However, findings also revealed that the specific number of responses requested in the instruction has to be taken into account as a decisive factor influencing the response selection process and ultimately data quality %K web surveys %K visual design %K interactive feedback %K satisficing %K data quality %U https://journals.sagepub.com/doi/full/10.1177/0894439317748890
