Hello Briony,

'Comparison' and 'Normal' data entry is a property of the codeset rather than the item being coded. To use comparison/double coding on a subset of items you would need to change the property of the coding tool and then just work on that subset of items. If you moved to other items outside of that subset you would still be using comparison coding.

You could set up a coding allocation for that subset to be sure you only coded those items. When you were done double coding those items you could then change the property of the coding tool back to 'Normal' data entry. If that subset was already coded before you started double coding you would first need to 'uncomplete' that coding so the second reviewer would not see that already applied codes.

Best regards,

Jeff
