Percent ink time (Command)
Total time pen is in contact with paper in command condition
This variable is only available in MARS and in Clinical Core.
Percent ink time in the command condition is captured during the digital Clock Drawing Test (dCDT) using digital pen technology. See the digital pen device category description for more information.
Participants are asked to use the digital pen to "draw the face of a clock with all of the numbers and set the hands to 10 after 11." This variable indicates the percentage of time the pen is in contact with the paper while performing the command.
