How to Blind Variables in Ripple

Blinding variables restricts access to sensitive data, allowing only Study Admins to view the actual values. Other users, such as Study Leaders and Research Assistants (RAs), will see an anonymous string instead.

Steps to Blind a Variable:

1. Navigate to Study Settings

   • Go to the Study Settings tab.
   • Select the Requirements section.
   • Scroll down to Custom Variable section.

2. Create or Select a Custom Variable

   • Either create a new custom variable or select an existing Global variable from the list.

3. Enable Blinding

   • Locate the “Blind” checkbox next to the custom variable.
   • Check the box to restrict access.

4. Save Changes

   • All changes will autosave the new settings.

Once blinded, only Study Admins will be able to view the variable’s value. Other users will see an anonymous string instead.
