Additional assumptions specific to the C-SSRS BASELINE are listed below.

The C-SSRS BASELINE is BASELINE is a suicidal ideation rating scale. It 's a is a standard questionnaire administered on a CRF that is typically used in clinical trials to identify subjects at risk for suicidal ideation and behavior. 

1. The questionnaire is divided into 3 sections namely : Suicidal Ideation, Intensity of Ideation, and Suicidal Behavior.

For this section of the C-SSRS BASELINE, QSORRES is populated with the text description while the numeric rating is represented in the standardized character and numeric result variables QSSTRESC and QSSTRESN.
2. The C-SSRS BASELINE instrument is evaluated for multiple time points. The time period of evaluation for the C-SSRS BASELINE is populated as an evaluation interval in ISO 8601 format in QSEVLINT when the interval can be precisely described as a duration, or as a text value in QSEVINTX when it cannot be precisely described as an ISO 8601 duration. The evaluation interval for the C-SSRS BASELINE is populated in the QSEVINTX field as an evaluation interval text value, since it cannot be precisely described as an ISO 8601 duration. The evaluation interval for the C-SSRS BASELINE is "LIFETIME" (QSEVINTX = "LIFETIME").

8. A derived record is created and a QS supplemental qualifier variable is used to indicate an item was conditionally branched. When an item is not done due to conditional branching, it is represented as follows:

   1. QNAM = “QSCBRFL”, QLABEL = “Conditional Branched Item Indicator “, QVAL = “Y”. (This is a QS supplemental qualifier variable.)      

   2. QSSTAT = "NOT DONE", and QSREASND is missing

   3. QSORRES, QSSTRESC and QSSTRESN are set to null (missing)
9. Records are created in qs.xpt for every item on the sponsor's version of the instrument.
   1. For items not done due to conditional branching, refer to assumptions 4 and 5.
   2. In the unexpected situation where the reason is unknown, then QSORRES, QSSTRESC and QSSTRESN are all missing, QSSTAT = "NOT DONE", and QSREASND is missing.

10. Some responses to the C-SSRS BASELINE items exceeded the 200-character limit for the QSORRES variable and needed to be reduced to fewer than 200 characters. Section 4, SDTM Mapping Strategy, indicates which item responses were revised in order to fit the 200-character limit. 

11. Terminology

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

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

3.2 Example for the C-SSRS BASELINE QS Domain Model

The C-SSRS BASELINE example below shows the terminology used to implement the instrument in the QS domain. This example shows the data for 1 subject collected at baseline (v1) and another subject at baseline (v1) and visit 2 for the C-SSRS BASELINE 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 a result is character only, the result is transformed into the standard character representation in QSSTRESC and QSSTRESN is null.

The table represents the items from the C-SSRS BASELINE instrument.

The table represents the items from the C-SSRS BASELINE instrument.

The SUPPQS dataset shows the items in the QS dataset which have assigned responses due to conditional branching.

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.

QSSCAT alignment with QSTESTCD.

As stated in Section 3.1 assumptions, Assumptions for the QS Domain Model, items on the C-SSRS BASELINE are grouped into subcategories. The following table below includes the subcategory names along with the applicable item numbers for each category.
