Dear Community,

I'm conducting a survey using both Qualtrics and another survey platform. The initial segment of the study will occur on the second platform, with participants being directed to the Qualtrics survey through personal links generated in Qualtrics and stored in their contact data table on the other platform.

Due to data security policies, I'm unable to access participant data on the first survey platform. However, I aim to pseudonymously link participants' responses from the other survey platform to Qualtrics survey responses using the Qualtrics personal links stored in the other platform. I'm seeking a solution to store the Qualtrics personal links along with participant responses to make the matching possible. Is there a way to achieve this in Qualtrics?

In subsequent stages, I plan to conduct two follow-up surveys with the same individuals on Qualtrics at different points in time. However, they now will be contacted via email and not via the other survey platform. I want to store their responses from the baseline and the following surveys in such a way that I am able to match individual responses across time and surveys. Is there a method to implement what I've described?

Thank you in advance for your help!

Best,

Kor
