About Questionnaires, Ratings, and Scales

Questionnaires, ratings, and scales (QRS) are used to assess the impact of tobacco products on the health of individuals and populations. QRS are standardized and often validated instruments. Given this, implementation of collection, tabulation, and analysis standards per this guide is specialized to maintain instrument standardization and, when applicable, the validity of validated instruments. CDISC provides descriptions for different types of QRS instruments and develops and publishes supplemental guidance for individual QRS instruments when the instrument is in the public domain or when permission has been granted by the copyright holder. CDISC QRS supplements are maintained as stand-alone guides available on the QRS page of the CDISC website at https://www.cdisc.org/foundational/qrs.

The TIG provides general guidance for the implementation of collection, tabulation, and analysis standards for QRS instruments. QRS supplements are used with the TIG to describe detailed guidance for implementation. QRS supplements support guidance in the TIG by providing a single source for standard annotated CRFs for collection, tabulation, and analysis dataset content conventions; controlled terminology; and examples for QRS instruments. 

The following table lists assessments that are being pursued as potential supplements as part of the development work for this guide. QRS supplements are managed as publications separate from this guide, may or may not be finalized at the time of publication of this guide, and depend on copyright approval where applicable. CDISC cannot produce supplements for copyrighted measures without the express permission of the copyright holder. Users of this guide can refer to the QRS page of the CDISC website if a measure of interest is not included in the table. New measures are developed on an ongoing basis and all supplements are made available on the website as they are developed. See CDISC COP 001 at https://www.cdisc.org/about/bylaws for details on implementing or requesting development of CDISC standards.
