I have a brief question about a two-survey study. I would like the participants to complete two separate surveys, where at least 28 days should pass between taking the first and second survey. Ideally, I would like to have this study be anonymized, because of sensitive information asked. The problem is that for the analysis I need to make sure that for each participant I need to know which responses to the survey belong to which responses of the second survey.
Does Limesurvey provide the functionality to automatically match the responses of both surveys depending on the participant, without letting me know who the person was that completed the surveys?
