How identifiable are participants?

I’m trying to pacify my overly anxious IRB.
I will be posting a screening study to determine appropriate participants. I will then invite approved participants for a future study.
Will I have access to any identifiable participant data, at any stage?
Could someone tell me, in official Prolific terms, what, if any participant data I will personally have access to?
Again, this is to satisfy a bureaucracy but it is important for my documentation.

In addition to @timtak’s page, might be helpful to reference this page: Can I ask participants for their personal information / identifiers? – Prolific

Shows what you are explicitly barred from collecting via Prolific, which was useful for my IRBs where I was doing surveys only (was a little different when we were doing interviews).


Thank you! I appreciate you taking the time!
