With custom screening questions, you can qualify or exclude participants based on their answers to single or multi-choice questions at the start of your study.
How to add screening questions to your study
Eligibility screeners are built in to our Choose blocks, allowing you to use them to filter out participants at any stage of your study.
To filter our participants based on their answers, simply:
1. Open your study in the Wondering Study Builder.
2. Add a new "Choose" block to your study, and move it to the place in your study where you want the screening questions should be asked. Usually that's at the beginning of the study.
3. Toggle on "Eligibility screener" within your Choose block to show the screener settings:
4. You'll now see screening logic appear next to each answer choice.
5. For each answer option, choose between "Accept" and "Reject".
Selecting "Accept" means participants choosing that option will continue with the study.
Selecting "Reject" means participants choosing that option will be immediately screened out.
6. Once you're done, participants who pick options that don't reject them from your study will continue to the next block in your study, while those who don't will see a thank you message.
By combining multiple screening questions and adding them to the start of your study, you can easily filter out participants that you don't want from participating in your study.

You can! This guide explains how to customize the message participants who are screened out see in your study.
How panel credits work when using screening questions
If you recruit from our panel and use screening questions to screen out participants, you'll only be charged for participants that pass your screeners.
If you're using panel participants and use screening questions, each participant costs 5 panel credits per participant that completes your study. This ensures that we can compensate participants for completing your screening questions, even if they get screened out.
To make sure we can find participants for your study even when you include screening questions in your study, we first send out your study to a minimum 85 participants from our panel if your study has not yet hit its response goal. This initial batch lets us gauge the incidence rate (the percentage of invited participants who meet your screener’s requirements).
If fewer than 10 % of those invited qualify, the panel order will be cancelled and refunded. A very low incidence rate usually means the screener questions or logic need adjusting.
