David Cella, PhD. , owns the copyright for the FACT-HEP G V4 instrument and has granted CDISC permission to include this supplement in the CDISC inventory of QRS data standards supplements. Hence, CDISC developed QSTESTCD and QSTEST for each item based on the actual text on the instrument.

The CDISC documentation of this instrument consists of: (1) controlled terminology, (2) standard database structure with examples, and (3) CRF(s) annotated with the CDISC SDTMIG variables with submission values. 

Note: CDISC Controlled Terminology is maintained by National Cancer Institute (NCI) Enterprise Vocabulary Services (EVS). The most recent version should be accessed through the CDISC website at: https://www.cdisc.org/standards/terminology/controlled-terminology.

CDISC has developed this documentation at no cost to the copyright holder or any additional cost to users of the instrument beyond the normal license fees charged by the copyright holder.

CDISC acknowledges Dr. David Cella and FACIT.org, for the approval to include the FACT-HEP V4 in the CDISC data standards.

3 The QS Domain Model

3.1 Assumptions for the QS Domain Model

All assumptions and business rules described in the SDTMIG QS All assumptions and business rules described in the SDTMIG QS domain are applicable to this supplement. Additional assumptions specific to the FACT-HEP G V4 are listed below.

The FACT-HEP G V4 is a multiple-choice health-related general quality of life questionnaire about problems associated with hepatobiliary cancer. It consists of 45 27 items rated on a 5-point scale.

1. All items rated on a 5-point scale include a numeric rating (0-4) and a definition of what is represented by the rating (e.g., 0 = "Not at all", 4 = "Very much"). For the FACT-HEP G V4, QSORRES is populated with the text description; the numeric rating is represented in the standardized character and numeric result variables QSSTRESC and QSSTRESN.

   1. FAC01514 FAC00114 may be rated on a 5-point scale or the subject may prefer not to answer. When the checkbox is marked that the subject prefers not to rate answer the item, this is noted with QSSTAT = "NOT DONE" and QSREASND = "PREFER NOT TO ANSWER". QSORRES, QSSTRESC, and QSSTRESN are all missing.

2. The time period of evaluation for the FACT-HEP G V4 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 FACT-HEP G V4 is the past 7 days (QSEVLINT = "-P7D").

3. Items are divided into 5 subcategories represented 4 subcategories

   represented in QSSCAT: "PHYSICAL WELL-BEING", "SOCIAL/FAMILY WELL-BEING", "EMOTIONAL WELL-BEING", and "FUNCTIONAL WELL-BEING", and "ADDITIONAL CONCERNS".

4. 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.

5. The FACT-HEP G V4 instrument includes subscale scores for each subcategory in addition to trial outcome index, FACT-G, and total scores a total score per FACIT.org's scoring materials and are considered as captured data on the CRF and are 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 FACIT.org.

   1. Subscores and total scores are represented in QSORRES.

   2. If scores are received or derived by the sponsor, it is recommended that they are submitted to SDTM and verified in ADaM whenever feasible.
6. Terminology

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

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

3.2 Example for the QRS FACT-HEP V4 QS Domain Model

The FACT-HEP V4 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 FACT-HEP V4 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.

1. 1. that they are submitted to SDTM and verified in ADaM whenever feasible.
2. Terminology

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

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

3.2 Example for the QRS FACT-G V4 QS Domain Model

The FACT-G V4 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 FACT-G V4 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.
