The exclusion period stops participants who recently completed a study with your team from confirming a spot in your new study. Use it to avoid bias, or to avoid re-testing designs with someone who has already seen them.
Setting it
You'll find the exclusion period among the audience filters on your study's Recruit tab. Choose how far back the exclusion reaches: participants who completed one of your team's studies in the past 3, 6 or 12 months.
How it works
The exclusion applies at confirmation, not application. Excluded participants can still see and apply to your study, and you can even invite them.
If an excluded participant tries to confirm, the system blocks them and tells them they're ineligible due to recent involvement in similar research.
The exclusion covers studies run by your whole team, not just your own.
Why do I still see familiar names applying?
Participants don't know which company a listed study belongs to, so people you've spoken to before will sometimes apply again. That's expected. Invite whoever looks right and let the system catch any repeats at confirmation.
