David Cella, PhD. , owns the copyright for the FACT-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.

These materials discuss and/or include the FACIT Measurement System, which is owned exclusively by Dr. David Cella. No part of the FACIT Measurement System may be reproduced, distributed, or transmitted in any form or by any means, including photocopying, recording, or other electronic or mechanical methods, without the prior written permission of Dr. David Cella and payment of any applicable fees.

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. 

...

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

3. Items are divided into 4 subcategories

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

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 FACT-G V4 instrument includes subscale scores for each subcategory in addition to 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.

The following table

...

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, items on the FACT-G V4 are grouped into subcategories. The following 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.
