Hello all,
Hoping someone can assist.
I am hoping to complete a 3-year longitudinal study of approximately 500 participants. I need to track individual participant performance over the 3 years.
However, to comply with ethics requirements I can never know any identifiable information in the first place. I am wondering if there is a way to collect the participant email in the first survey, without me ever seeing it, and replacing it with a participant ID of some kind which would allow me to send follow-up emails and track individual performance.
Thank you,
Richard
