Introduction To REDCap
Next Session Wednesday May 13, 2026 9:30-11:00
The presentation will last about one hour with time left for questions or feature demonstrations.
This introduction will cover just the basics, enough to enable you to create new projects, design forms, extract data, and share your project with others.

Yes, special formatting is needed for the branching logic syntax in 'checkbox' field types. For checkboxes, simply add the coded numerical value inside () parentheses after the variable name:
[variablename(code)]
To check the value of the checkboxes:
'1' = checked
'0' = unchecked
See the examples below, in which the 'race' field has two options coded as '2' (Asian) and '4' (Caucasian):
[race(2)] = "1"
Display question if Asian is checked
[race(4)] = "0"
Display question if Caucasian is unchecked
[height] >= 170 and ([race(2)] = "1" or [race(4)] = "1")
Display question if height is greater than or equal to 170 AND Asian OR Caucasian is checked
