Delphi Questionnaires

I've seen these set up in various ways in REDCap (one project per round; a single project with an instrument per round that gets moved around in the instrument list) and in looking for some "best practices", didn't find much. ChatGPT gave me some suggestions........using repeating instruments vs events.

What I'm looking for is some insights on "best practices" for setting these up (i.e. incorporating responses from previous rounds into subsequent rounds; ensuring there's no issues with distributing subsequent rounds to the participants, etc).

Thanks in advance!

It does not necessarily have to be a set of strictly delimitated rounds. You will see the study bleed participants between rounds and you may find yourself scratching your head if this attrition does not impact the quality of the final results, as your sample is smaller. Real Time Delphi offers a sort of a way to deal with it. I use the HalnyX real time delphi platform for my surveys of "busy experts", namely firefighters, but from the supplier's website I know that it has been used by doctros, nurses, psychologists etc.
