If you want to assign the results to each participant at the end of the survey, you can perfrom personalization through the participant list. Please use the column 'Reference text' for the personalization data. The stored data set fo the personalization is displayed in the individual results and export file (XLS, CSV, SPSS).
If you implement personalization at this point, the survey will no longer be anonymous at all. Please inform the participants that the survey is NOT anonymous and do not promise any anonymity.
If you have already assigned your participant list to the survey, later performed changes will not be imported from the list. Please edit the participant list directly in the survey, if you want to change anything later on.
