Questionnaires (QS) is a findings domain that contains used for data for from named stand-alone instruments designed to provide an assessment of a concept. Questionnaires have a defined standard structure, format, and content; consist of conceptually related items that are typically scored; and have documented methods for administration and analysis. Refer to Section x.x, Guidance for Questionnaires, Ratings, and Scales when implementing collection standards. Because the nature of QRS precludes implementers from modifying the published data collection structure, the TIG collection metadata does not include specifications for QRS. Instead, implementers should refer to instrument-specific QRS supplements on the QRS web page for example aCRFs, instrument-specific assumptions, and data examples.
