I have a group of 20 participants who will receive the same set of questions via email before and after an intervention. I need anonymous data returned to me, but need some way to identify each participant so I can track their responses to each individual question before and after the intervention so I can identify and analyze changes. Can I use hidden questions to do this? If so, how?
