In some surveys, the once per respondent option does not prohibit someone to re-answer from another device or forward it to others who are not representing our sample. Is there a way to avoid this on the online surveys?
Thank you in advance
Welcome to the community, @interviewaurvey! Maybe you could provide some codes to the respondents. When you have the data back to the server you could see if the codes are duplicate. If duplicate you could delete the duplicate records and manage a unique submission for the survey. Maybe out community should have better approach for this though.
Thank you very much for your prompt response. Your idea to generate codes and delete duplicates is good but do you have any idea how to do this? In practice, how can I produce codes on the kobo tool and link them to the panticipates?
