  • Converted the supplement to the current WIKI QRS supplement template.
  • Annotated CRF updated to the MSG V2.0 annotation guidelines
  • Copyright Status section was updated based on the latest Memorandum of Understanding signed between McMaster
    University and CDISC.
  • Reference for the CRQ-SAS FIRST ADMINISTRATION VERSION was updated to retain only the valid hyperlinks.
  • Updated the assumption to clarify that the CRQ-SAS First Administration consists of 20 items with each item graded on a 7-point or 8-point Likert scale.
  • Updated assumption 1.a to specify users need to follow the scoring solution in their approved copyright permission when the result is“8 = Not Done”.
  • Removed the QSEVAL assumption and variables as this is not captured on the CRF and no assumptions are made on potential values.
  • The “QSBLFL” variable was replaced with the “QSLOBXFL” variable in the example to represent a baseline response for visit 1.
  • An additional subject was added to the data example to show how missing data is handled when the instrument was not completed.

McMaster University will distribute the CDISC supplement package to sponsors when they are approved to use this instrument. Hence, CDISC developed QSTESTCD and QSTEST for each item based on the actual text on the instrument.

The “Chronic Respiratory Disease Questionnaire Self-Administered Standardized (CRQ-SAS)”, authored by Drs.

  1. The scale points include a numeric rating (1-7) and a definition of what is represented by the rating (e.g., 1 = "All of the time"). For the CRQ-SAS FIRST ADMINISTRATION VERSION, QSORRES is populated with the text description while the numeric rating is represented in the standardized character and numeric result variables QSSTRESC and QSSTRESN.
           a.  The first 5 questions have a questionnaire choice of “8 = Not Done”. The result of “8” is included in QSSTRESC and QSSTRESN; however, users need to follow the scoring solution in their approved copyright permission.

  2. The time period of evaluation for theCRQ-SAS FIRST ADMINISTRATION VERSION is populated in the QSEVLINTfield in ISO 8601 format when the evaluation interval can be precisely described as duration. The evaluation interval for the CRQ-SAS FIRST ADMINISTRATION VERSION is the LAST 2 WEEKS (QSEVLINT = "-P2W"). 

  3. Records Records are created in qs.xpt for  for every collected item on the the instrument: 

    1. For items with no data, QSORRES, QSSTRESC, and QSSTRESN are all missing and QSSTAT = "NOT DONE". If the reason is known then that reason is represented in QSREASND (e.g., QSREASND = "PREFER NOT TO ANSWER"). If the reason is unknown, then QSSTAT = "NOT DONE" and QSREASND is missing.

    2. Due to the variability of copyright holder and public domain derived score generation processes, records are not included for derived subscores or total scores that are not provided.

  4. Terminology

    1. QSCAT, QSTESTCD, QSTEST, QSORRES, QSSTRESC, and QSSTRESN values are included in CDISC Controlled Terminology.

    2. A full list of value sets for the result fields is provided in Section 4, SDTM Mapping Strategy.
