The FAACT V4 is a multiple-choice health-related quality of life questionnaire about problems associated with hepatobiliary cancer. It consists of 39 items rated on a 5-point scale. The FACT-G is included as the first 27 items in the FAACT V4. 

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 FAACT 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. FAC06514 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 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 FAACT 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 FAACT V4 is the past 7 days (QSEVLINT = "-P7D").

3. Items are divided into 5 subcategories represented in QSSCAT: "PHYSICAL WELL-BEING", "SOCIAL/FAMILY WELL-BEING", "EMOTIONAL WELL-BEING", "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 = "PREFER NOT TO ANSWER"). If the reason is unknown, then QSSTAT = "NOT DONE" and QSREASND is missing.

5. The FAACT V4 instrument includes subscale scores for each subcategory in addition to trial outcome index, FACT-G, and total scores 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.
