Participants who do not consent to take part in your study should be redirected to a end of survey message, which asks them to return their submission so their study place becomes available again.
To do this,
“As you do not wish to participate in this study, please return your submission on Prolific by selecting the 'Stop without completing' button.”
3. Record participant IDs using a query string
articipant IDs within , so you can match your survey responses to individual Prolific submissions.
4. Validate your screening questions by asking them again in your survey
exactly as they appear on Prolific. This will allow you to confirm that participants’ prescreening responses are accurate, so you can be sure you are obtaining your desired sample.
We recommend redirecting participants to a separate end of survey message if their responses do not match the prescreening criteria you have aon Prolific. To do this, :
“You are ineligible for this study, as you have provided information which is inconsistent with your Prolific prescreening responses. Please return your submission on Prolific by selecting the 'Stop without completing' button.”
(see step for instructions).
5. Preview your study onand Prolific
After completion of the previous 4 steps,
preview your study extensively to check that is working as you expect it to, and to check that and it is redirecting to the Completion URL at the end.
