General
Questionnaires, Ratings, and Scales (QRS) are very common in clinical trial protocols. CDISC has published many supplements to provide users information on how to structure the QRS data in a standard format using SDTM. Users can view the normative information regarding relevant CDISC Controlled Terminology (CT) codelists and terms, and how they map and apply in SDTM datasets. CDISC Library provides users a machine-readable version of this normative information, such as the exact CT term to use in the SDTM --CAT variable, an item's --TEST and --TESTCD, one-to-one pairing of --TEST and --TESTCD, ordering of items, and lastly, response codelists and terms for each applicable item.
