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 FOLLOW-UP ADMINISTRATION VERSION are listed below.
The CRQ-SAS FOLLOW-UP ADMINISTRATION VERSION is a multiple-choice instrument 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.
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 FOLLOW-UP 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.The time period of evaluation for the CRQ-SAS FOLLOW-UP ADMINISTRATION VERSION is populated in the QSEVLINT field in ISO 8601 format when the evaluation interval can be precisely described as duration. The evaluation interval for the CRQ-SAS FOLLOW-UP ADMINISTRATION VERSION is the LAST 2 WEEKS (QSEVLINT = "-P2W").
Records are created in qs.xpt for every item on the instrument:
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
QSCAT, QSTESTCD, QSTEST, QSORRES, QSSTRESC, and QSSTRESN values are included in CDISC Controlled Terminology.
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 FOLLOW-UP ADMINISTRATION VERSION QS Domain Model
The CRQ-SAS FOLLOW-UP 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 visit 3 and visit 4 for the CRQ-SAS FOLLOW-UP 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.
We are unable to make the example consistently show blue in the Wiki. All examples are updated for each QRS instrument so we ask that you please review the example below.
The table represents the items from the CRQ-SAS FOLLOW-UP ADMINISTRATION VERSION instrument.

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.
Include mappings for all sets of result values. For ease of use of this template, the complete set of response values for the example in Section 3.2 is not included.
If the instrument has been entered into QRS Maker (all instruments should be), then the complete set of response values can be copied from QRS Maker and pasted into this supplement.
Some example mappings are below.
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 FOLLOW-UP 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.
| QSSCAT | QSTESTCD |
|---|---|
| EMOTIONAL/INFORMATIONAL SUPPORT | QSSS0101 - QSSS0108 |
| TANGIBLE SUPPORT | QSSS0109 - QSSS0112 |
| AFFECTIONATE SUPPORT | QSSS0113 - QSSS0115 |
| POSITIVE SOCIAL INTERACTION | QSSS0116 - QSSS0118 |
| ADDITIONAL ITEM | QSSS0119 |
For public domain instrument's published QRS responses
If this is a public domain instrument that has an individual item with published QRS responses, include the following sentence above the—TESTCDs listed with their responses.
The controlled response terminology for the tests below is named QSTESTCDOR for the variable RSORRES and QSTESTCDSTR for the variables RSSTRESN and RSSTTRESC.
- If this is a public domain instrument with published QRS responses, include the following sentence above the—TESTCDs listed with their responses.
- The controlled response terminology for the tests below is named QSTESTCDTXXXOR for the variable RSORRES and QSTESTCDTXXXTSTR for the variables RSSTRESN and RSSTTRESC.
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"
| QSORRES | QSSTRESC | QSSTRESN |
|---|---|---|
| Original result 1 | 0 | 0 |
| Original result 2 | 1 | 1 |
| Original result 3 | 2 | 2 |
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.
For public domain instrument's published QRS responses
If this is a public domain instrument with published QRS responses, include the following sentence above the—TESTCDs listed with their responses. This approach used the CDISC QRS CT instrument's SYNONYM as part of the codelist name.
The controlled response terminology for the tests below is named SYNONYMSET1OR for the variable RSORRES and SYNONYMSET1STR for the variables RSSTRESN and RSSTTRESC.
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"
| QSORRES | QSSTRESC | QSSTRESN |
|---|---|---|
| I never take longer than 30 minutes to fall asleep | 0 | 0 |
| I take at least 30 minutes to fall asleep, less than half the time | 1 | 1 |
| I take at least 30 minutes to fall asleep, more than half the time | 2 | 2 |
| I take more than 60 minutes to fall asleep, more than half the time | 3 | 3 |
Omit the QSSTRESN column when it is not applicable to the dataset.
QSTESTCD = "test code" QSTEST = "test name"
| QSORRES | QSSTRESC |
|---|---|
| yes | Y |
| no | N |
For public domain instrument's published QRS responses
If this is a public domain instrument with published QRS responses, include the following sentence above the—TESTCDs listed with their responses.
- The controlled response terminology for the tests below is named QSTESTCDTXXXOR for the variable RSORRES and QSTESTCDTXXXTSTR for the variables RSSTRESN and RSSTTRESC.
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"
| QSORRES | QSSTRESC | QSSTRESN |
|---|---|---|
| I have not experienced the physical sensation of feeling weighted down and without physical energy | 0 | 0 |
| I have occasionally experienced periods of feeling physically weighted down and without physical energy, but without a negative effect on work, school, or activity level | 1 | 1 |
| I feel physically weighted down (without physical energy) more than half the time | 2 | 2 |
| I feel physically weighted down (without physical energy) most of the time, several hours per day, several days per week | 3 | 3 |
5 Supplemental Qualifier Name Codes
The instrument used as an example in this template did not require supplemental qualifiers, but this section has been included to provide guidance on those instruments which do require supplemental qualifiers. (Many instruments do not require it.) Text that always will be in the section when it is included has been left black.
Additional rows will be required in the suppqs.xpt dataset for each supplemental qualifier needed.
Remove Section 5 if it does not apply to the new instrument.
The following table contains additional standard name codes for use in the Supplement Qualifiers for Questionnaires (SUPPQS) special purpose dataset.
| QNAM | QLABEL | QVAL |
|---|---|---|
| Appropriate variable name to provide more information about data in qs.xpt, no more than 8 characters long (e.g., CONTACT). | Label for QNAM (e.g., Contact Type) | Value of QNAM ( e.g., SUBJECT VISIT) |
