Hi,
I'm trying to set up a survey which uses a link I can send out via email to allow participants to enter data a three time points. I want to be able to link the responses using an anonymous number but I cannot collect any identifiable details (eg: name, email) and can't use qualitrics to send the emails out. Is there a way to link different surveys via a number rather than a name or email? Is there a way to enter contacts using anonymous numbers I create so the system can expect responses from these participants?
I've tried to do this via redcap previously but keep running into the problem that I can't collect emails because the project is research and these are the stipulations of my ethical approval.
Thanks in advance for any advice.
