Hi, I am using Survey Signal and Qualtrics to conduct an intensive longitudinal study. Participants receive 5 texts/day with an anonymous links to the same Qualtrics survey. Somehow, participants are completing multiple surveys back-to-back. I would like to prevent participants from taking the same survey within 29 minutes of completing the last survey. Is there a way to do this? The prevent ballot box stuffing tool doesn't work for me in this case because I DO want participants to answer the same survey 5 times/day - just not back-to-back. Thanks!
