Hello,
I am using Qualtrics to develop a survey with regard to measure the impact of an intervention through an RCT. We will do three measurement moments (i created three different projects in qualtrics for that: measurement 1, measurement 2, measurement 3 - to ensure not mixing anything up) and the data need to be anonymous. For that reason I created an authenticator: respondents need to fill in a code (received from me) before they can access the survey. That way I can afterwards link the completed surveys from the respondents through their code. This looks like this:
So far, this works very fine. However, i now want the following: if a respondents completed the survey successfully, and goes back to the questionnaire, fills in their code - I want a message to be shown: 'You have already completed this survey. Thanks for your cooperation!'. I know their is a standard check for this in 'survey options', but it doesn't seem to connect/work to the code of the participants that I filled in through the authenticator. Can anyone help me with this?
I hope my question is clear?
Thanks a lot for you help!
Regards,
