REDCap logic

On the lefthand side, click on Designer and go to Survey Queue setup.

For this example, we are using MNBS that was added to SPA7T project in October 2026! Ensure that the measure is activated and ready for use. You can activate/deactivate clicking this button here.

If you want your survey to come after another (automatically), you can click the checkbox and also indicate which particular survey (under which arm/visit type) you want it to go after. ALSO, be sure to check the box on the farthest righthand side. This helps RedCap know you want this survey to autostart.

Then, you're all done!!! Be sure to submit all changes for review.

Important note: If some surveys are unique to age or sex/gender, you will need to modify the logic. For example, in the screenshot below we have the MNBS, DT-AS, and WHOQOL-BREF. MNBS is administered to all participants, whereas the DT-AS and WHOQOL-BREF are only for adults to complete.

1. Add all the items/survey questions onto the new instrument that you created

2. Once all items/survey questions have been added, click on the green arrows icon

3. insert the logic based on your variable name and values assigned to responses then click Save

4. Nice! You did it! Remember to Submit Changes for Review when you are done!
