3 The QS Domain Model

3.1 Assumptions for the QS Domain Model

All assumptions and business rules described in the SDTMIG QS domain are applicable to this supplement. Additional assumptions specific to the CRQ-SAS FIRST ADMINISTRATION VERSION are listed below.

The CRQ-SAS First Administration is a multiple choice patient reported outcome (PRO) assessment that clinicians may use to measure health-related quality of life (HRQL) in patients with chronic respiratory diseases.  It consists of 20 items with each item graded on a 7-point Likert scale.

...

Records are created in qs.xpt for every item on 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.

...

Terminology

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

2. A full list of value sets for the qualifier, timing, result, and unit fields is provided in Section 4, SDTM Mapping Strategy. (Note: Only the result field is always used. Include qualifier, timing, and unit fields as needed and remove this note.)

3 The QS Domain Model

3.1 Assumptions for the QS Domain Model

All assumptions and business rules described in the SDTMIG QS domain are applicable to this supplement. Additional assumptions specific to the CRQ-SAS FIRST ADMINISTRATION VERSION are listed below.

The CRQ-SAS First Administration is a multiple choice patient reported outcome (PRO) assessment that clinicians may use to measure health-related quality of life (HRQL) in patients with chronic respiratory diseases.  It consists of 20 items with each item graded on a 7-point or 8-point Likert scale.

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 are created in qs.xpt for every collected item on 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.

3.2 Example for the CRQ-SAS FIRST ADMINISTRATION VERSION QS Domain Model

The CRQ-SAS FIRST ADMINISTRATION VERSION example below shows the terminology used to implement the instrument in the QS domain. This example shows the data for 2 subjects collected at the baseline visit for the CRQ-SAS FIRST ADMINISTRATION VERSION instrument. The example uses CDISC Controlled Terminology for QSTESTCD, QSTEST, and QSCAT. All original results, matching the CRF item response text, are represented in QSORRES. This result is then represented as a standard numeric score in QSSTRESN and as a standard character representation in QSSTRESC.

The table represents the items from the CRQ-SAS FIRST ADMINISTRATION VERSION instrument. Subject 2324-P0002 was not evaluated on this instrument. Since the visit was missed, the reason for not completing the visit was not collected, no date is assumed for when the visit would have occurred.

3.2 Example for the CRQ-SAS FIRST ADMINISTRATION VERSION QS Domain Model

The CRQ-SAS FIRST ADMINISTRATION VERSION example below shows the terminology used to implement the instrument in the QS domain. This example shows the data for 1 subject collected at the baseline visit for the CRQ-SAS FIRST ADMINISTRATION VERSION instrument. The example uses CDISC Controlled Terminology for QSTESTCD, QSTEST, and QSCAT. All original results, matching the CRF item response text, are represented in QSORRES. This result is then represented as a standard numeric score in QSSTRESN and as a standard character representation in QSSTRESC." When the results are character only, then use these sentences next, "This result is then transformed into the standard character representation in QSSTRESC. QSSTRESN is null as there are no standardized numeric results for this instrument.

...

The following is for illustrative purposes and would not really be included for the IDS-SR instrument in this template. It provides an example of what would need to be included if the instrument required supplemental qualifiers (see Section 5 Supplemental Qualifier Name Codes):

Text that would remain unchanged has been left in black:

The evaluation interval text value for data collection needs to be populated in SUPPQS as follows. The standard terminology for QNAM and QLABEL are listed below.

4 SDTM Mapping Strategy

This section is used for reference regarding the CRF data capture and to understand the alignment of the instrument to the SDTM QS domain. It also provides guidance on how the result variables (QSORRES, QSSTRESC, and QSSTRESN) should be populated.

...

For QRS instruments with subcategories:

When subcategories are used on an instrument, a table with the following introduction information should appear before the mappings for results.

QSSCAT alignment with QSTESTCD

As stated in Section 3.1 assumptions, items on the CRQ-SAS FIRST ADMINISTRATION VERSION are grouped into subcategories. The table below includes the subcategory names along with the applicable item numbers for each category. The values of the subcategories are used to populate QSSCAT and are annotated on the CRF.

...

If all items have the same original result values, with the same standardized character and numeric values, then only include one table showing the values of QSORRES/QSSTRESC/QSSTRESN and put "All QSTESTCDs" (title case "All", and in quotes) above the table:

"All QSTESTCDs"

...

Similarly, if some, but not all, QSTESTCDs share the same original result and standardized values, then the QSTESTCD and corresponding QSTEST values are put in a list above the table rather than providing a separate table for each QSTESTCD/QSTEST.

...

If there are responses that correspond to non-consecutive items or 1-7 consecutive items, include the test codes and test names above the table with the responses as follows:

QSTESTCD = "test code 1" QSTEST = "test name 1"

QSTESTCD = "test code 4" QSTEST = "test name 4"

QSTESTCD = "test code 5" QSTEST = "test name 5"

QSTESTCD = "test code 6" QSTEST = "test name 6"

QSTESTCD = "test code 7" QSTEST = "test name 7"

QSTESTCD = "test code 8" QSTEST = "test name 8"

QSTESTCD = "test code 15" QSTEST = "test name 15"

QSTESTCD = "test code 22" QSTEST = "test name 22"

QSTESTCD = "test code 27" QSTEST = "test name 27"

QSTESTCD = "test code 29" QSTEST = "test name 29"

4 SDTM Mapping Strategy

This section is used for reference regarding the CRF data capture and to understand the alignment of the instrument to the SDTM QS domain. It also provides guidance on how the result variables (QSORRES, QSSTRESC, and QSSTRESN) should be populated.

QSTESTCD = "CRQ0101" QSTEST = "CRQ01-Feeling Emotional"

QSTESTCD = "CRQ0102" QSTEST = "CRQ01-Take Care of Basic Needs"

QSTESTCD = "CRQ0103" QSTEST = "CRQ01-Walking"

QSTESTCD = "CRQ0104" QSTEST = "CRQ01-Performing Chores"

QSTESTCD = "CRQ0105" QSTEST = "CRQ01-Participate in Social Activities"

QSTESTCD = "CRQ0106" QSTEST = "CRQ01-Felt Frustrated or Impatient"

QSTESTCD = "CRQ0107" QSTEST = "CRQ01-Feeling of Fear or Panic"

QSTESTCD = "CRQ0109" QSTEST = "CRQ01-Embarrassed by Coughing"

QSTESTCD = "CRQ0112" QSTEST = "CRQ01-Feel Upset, Worried or Depressed"

QSTESTCD = "CRQ0115" QSTEST = "CRQ01-Felt Low in Energy"

QSTESTCD = "CRQ0116" QSTEST = "CRQ01-Felt Discouraged or Down"

QSTESTCD = "CRQ0117" QSTEST = "CRQ01-Felt Worn Out or Sluggish"

QSTESTCD = "CRQ0119" QSTEST = "CRQ01-Feel Upset Diff Getting Breath"

QSTESTCD = "CRQ0120" QSTEST = "CRQ01-Felt Restless, Tense or Uptight"

QSTESTCD = "CRQ0108" QSTEST = "CRQ01-Fatigue"

QSTESTCD = "CRQ0110" QSTEST = "CRQ01-Confident to Deal With Illness"

QSTESTCD = "CRQ0113" QSTEST = "CRQ01-Control of Breathing Problems"

QSTESTCD = "CRQ0114" QSTEST = "CRQ01-Feel Relaxed and Free of Tension"

QSTESTCD = "CRQ0111" QSTEST = "CRQ01-Energy"

QSTESTCD = "CRQ0118" QSTEST = "CRQ01-Happy, Satisfied or Pleased"

...

Omit the QSSTRESN column when it is not applicable to the dataset.

QSTESTCD = "test code" QSTEST = "test name"

...

For responses that are for 8 or more consecutive items, an override label should be used in QRS Maker to show the items that are included as follows:

QSTESTCD = "first test code in sequence" QSTEST = "first test name in sequence" through

QSTESTCD = "last test code in sequence" QSTEST = "last test name in sequence"

...

5 Supplemental Qualifier Name Codes

The following table contains additional standard name codes for use in the Supplement Qualifiers for Questionnaires (SUPPQS) special purpose dataset.
