...

...

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"

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"

1 Introduction

This document describes the CDISC implementation of the Columbia-Suicide Severity Rating Scale Baseline (C-SSRS BASELINE) instrument.

CDISC does not modify questionnaires, ratings, and scales (QRS) instruments to meet Clinical Data Acquisition Standards Harmonization (CDASH) case report form (CRF) standards.

The representation of data collected for this instrument is based on the Study Data Tabulation Model Implementation Guide (SDTMIG) Questionnaires (QS) domain model, which can be found on the CDISC website at: https://www.cdisc.org/standards/foundational/sdtmig.

These specific implementation details for this instrument are meant to be used in conjunction with the SDTMIG. All CDISC QRS documentation packages can be found on the CDISC website at: https://www.cdisc.org/standards/foundational/qrs.

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 C-SSRS BASELINE are listed below.

The C-SSRS BASELINE is a multiple-choice instrument that clinicians may use to assess the severity of depressive symptoms. It consists of 30 items, each rated on a 4-point scale. A total score between 0-84 is also captured.

...

Include a description of scale score or other possible responses (You may need multiple numbered points for this, tho the IDS-SR did not.). For scale scores use the following language: The scale points include a numeric rating (0-3) and a definition of what is represented by the rating (e.g., 0 = "I never take longer than 30 minutes to fall asleep"). For the QRS Short_Name, QSORRES is populated with the text description while the numeric rating is represented in the standardized character and numeric result variables QSSTRESC and QSSTRESN. (replace this sentence for instruments with text only responses with “QSORRES and QSSTRESC are populated with the text description and QSSTRESN is not represented with a numeric value”.

...

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 = "LOGICALLY SKIPPED ITEM" or QSREASND = "PREFER NOT TO ANSWER"). If the reason is unknown, then QSSTAT = "NOT DONE" and QSREASND is missing.

...

If the instrument standards currently being developed includes logically skipped items, insert:  Some items on the QRS Short_Name may be logically skipped per the instrument instructions. Only one of the 2 oxygen saturation scales (RSTESTCD = "NEWS102" or "NEWS103") is completed for each subject. The other will be treated as a logically skipped item. In addition, item RSTESTCD = "NEWS104A" is only completed when the response to RSTESTCD = "NEWS104" is the amount of oxygen received (in L/min). A record is created in rs.xpt for all items. When an item is considered a logically skipped item, it is represented as follows:

1. RSSTAT = "NOT DONE".       

2. RSREASND = "LOGICALLY SKIPPED ITEM".
   

3. RSORRES, RSSTRESC, and RSSTRESN are set to null (missing).

...

Include this point if score(s) are submitted to SDTM. Update blue text: The QRS Short_Name instrument includes a total score (and other scores as needed.  If so, change "that is" to "that are") that is considered as captured data on the CRF and is not considered as derived in the example below. These scores may be submitted in SDTM or derived in the Analysis Data Model (ADaM) per scoring instructions from [Insert copyright holder's name or other source.].

1. If operationally defined by the sponsor, it is the sponsor's responsibility to set the --DRVFL flag based on their eCRF process to derive subtotals and total scores. An investigator-derived score will be considered a captured score and not flagged. When subtotal and total scores are derived by the sponsor, the derived flag (--DRVFL) is set to "Y". However, when the subtotal and total scores are received from a central provider or vendor, the value would go into --ORRES and --DRVFL would be null (see SDTMIG Section 4.1.8.1, Origin Metadata for Variables).

2. If scores are received by the sponsor, it is recommended that they are submitted to SDTM and verified in ADaM.

...

This language is currently under review. Evaluator information is only to be included when the information is collected directly on the CRF. instruments will no longer be using QSEVAL/QSEVALID; however RSEVAL/RSEVALID and FTEVAL/FTEVALID will continue to be used on Clinical Classifications and Functional Tests. Language for Clinical Classifications and Functional tests follows; language for instruments is currently under review. Remove this point if it does not apply.

For Clinical Classifications and Functional Tests (only when collected on the CRF):  *** This section to be updated.  QSEVAL/ID, FTEVAL/ID, and RSEVAL/ID will no longer be used.  Supplemental qualifiers will represent this information. *** For QRS Short_Name, the evaluator is defined as the (the appropriate term from controlled terminology). Alternatively, if only evaluator name or initials could be collected: For QRS Short_Name, sponsors should follow their internal data management procedures on representing the name or initials of the evaluator. CDISC Controlled Terminology is available for Evaluator (e.g., --EVAL = "HEALTH CARE PROFESSIONAL") and Medical Evaluator (e.g., --EVALID = "RATER 1"). To reiterate, only include this point if the evaluator/administrator is collected directly on the CRF.

...

Include this point if there are comments at the end of the instrument. Remove this point if it does not apply.: Comments located at the end of the QRS Short_Name will be recorded in the Comments domain (CO). All assumptions and business rules described in the SDTMIG CO domain are applicable.

...

Include this point if there are responses over 200 characters. Remove this point if it does not apply: Some responses to the QRS Short_Name 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.

...

Terminology

1. QSCAT, QSTESTCD, and QSTEST (and other variables such as QSORRESU as needed) 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.)

3.2 Example for the QRS Short_Name QS Domain Model

The QRS Short_Name 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 QRS Short_Name instrument. The example uses CDISC Controlled Terminology for QSTESTCD, QSTEST, and QSCAT. All original results are represented with preferred terminology in QSORRES. When there are numeric results, then use this sentence next, "This result is then transformed into the standard numeric score in QSSTRESN and a character representation of the standard numeric score 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."

...

Update the data in the table below to the current instrument. Include row descriptions as needed to highlight idiosyncrasies or items otherwise of note in this particular instrument. If only 1 or 2 row descriptions are needed, then the information should be included as a paragraph instead.

For the not done visit that is now being included in all QRS supplements, when no reason is collected, information should be included, either in the paragraph before, or as a row description as follows:

...

When the reason is collected for a not done visit, information or a row description should be added as follows:

...

...

...

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.
