Assessing the content validity of a Patient Reported Outcome Measure item pool for Rheumatoid Arthritis Disease Activity using cognitive interviews
Authors' conclusion
The findings indicate that the 12-item pool adequately captures relevant concepts of RA disease activity, with no additional items required and thus provide evidence of its content validity.
