1 Introduction
This document describes the CDISC implementation of the Asthma Nighttime Symptom Diary V1.0 0 (ANSD V1.0) questionnaireinstrument.
CDISC does did not modify this questionnaires, ratings, and scales (QRS) instruments to meet Clinical Data Acquisition Standards Harmonization (CDASH) case report form (CRF) standards. Jira showSummary false server Issue Tracker (JIRA) serverId 85506ce4-3cb3-3d91-85ee-f633aaaf4a45 key QRSSUPP-672
The representation of data collected for this questionnaire instrument is based on the Study Data Tabulation Model Implementation Guide (SDTMIG) Questionnaires (QS) domain domain model, which can be found on the CDISC website at: https://www.cdisc.org/standards/foundational/sdtmig.
These specific implementation details for this questionnaire 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.

The Critical Path Institute
owns the copyright for the ANSD V1.0 instrument and has granted CDISC permission to include this supplement in the CDISC library of QRS data standards supplements. Hence, CDISC developed QSTESTCD developed QSTESTCD and QSTEST for QSTEST for each item based on the actual text on the questionnaire. There may be many versions of this instrument in the public domain or copyrighted. CDISC has chosen to use this version as the data standard.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 (ANSD Annotated CRF.pdf)
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 Critical the Critical Path Institute for the approval to include the ANSD V1.0 in the CDISC data standards.

3 TheQSDomain Model
3.1 Assumptions for theQSDomain Model
All assumptions and business rules described in the SDTMIG QS SDTMIG QS domain are applicable to this supplement. Additional assumptions specific to the ANSD V1.0 are listed below.
The ANSD V1.0 is a 6-item PRO measure patient diary PRO instrument
to assess self-reported severity of asthma symptoms during the night. Each item is rated on an 11-point numeric rating scale. A total score is also capturedrepresented as described in the manual. Jira showSummary false server Issue Tracker (JIRA) serverId 85506ce4-3cb3-3d91-85ee-f633aaaf4a45 key QRSSUPP-676
The scale points include a 0 to 10 rating with 0 = "None", 10 = "As bad as you can imagine", and all points in between only having a numeric value. For the ANSD V1.0, QSORRES is populated with the text description for "None" and "As bad as you can imagine" and the numeric value for all other answers, while the numeric rating is represented in the standardized character and numeric result variables QSSTRESC and QSSTRESN.
- The time period of evaluation
for the ANSD V1.0 is populated in the the QSEVINTX when the evaluation interval can be precisely described as duration. The evaluation interval for the ANSD V1.0 is is, "since you went to bed last night" (QSEVINTX = "SINCE GOING TO BED").Jira showSummary false server Issue Tracker (JIRA) serverId 85506ce4-3cb3-3d91-85ee-f633aaaf4a45 key QRSSUPP-677 A total score, not collected on the ANSD v1.0 CRF but which is described in the manual, may be submitted as an Electronic Data Transfer (eDT) along with the individual item data for the ANSD v1.0. This original result will be recorded in QSORRES and a standardized representation of the score will be populated in QSSTRESC and QSSTRESN when it is included. The ANSD v1.0 total score is The ANSD V1.0 instrument includes an overall score

in the example below. These scores may be submitted in SDTM orJira showSummary false server Issue Tracker (JIRA) serverId 85506ce4-3cb3-3d91-85ee-f633aaaf4a45 key QRSSUPP-679
derived in the Analysis Data Model (ADaM) per scoring instructions from Critical Path Institute.Jira showSummary false server Issue Tracker (JIRA) serverId 85506ce4-3cb3-3d91-85ee-f633aaaf4a45 key QRSSUPP-680 - Subscores and overall scores are represented in--ORRES, --STRESC, and --STRESN.
- If subscores or overall scores are received or derived by the sponsor, it is recommended that they are submitted to SDTM and verified in ADaM whenever feasible. It is the sponsors responsibility to do this verification based on the instrument's user manual or instructions from the copyright owner.
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 written on a CRF 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).Jira showSummary false server Issue Tracker (JIRA) serverId 85506ce4-3cb3-3d91-85ee-f633aaaf4a45 key QRSSUPP-682
Terminology
QSCAT, QSTESTCD, and QSTEST values are included in CDISC Controlled Terminology.
A full list of value sets for the result field is provided in Section 4, SDTM Mapping Strategy.
3.2 Example for the ANSD V1.0 QS Domain Model
The ANSD V1.0 example below shows the terminology used to implement the instrument in the QS domain. This example shows the data for 1 subject 2 subjects
collected at the baseline visit for the ANSD V1.0 instrument. The example uses CDISC Controlled Terminology for QSTESTCD, QSTEST, and QSCAT. All original results are represented with preferred terminology in QSORRESQSORRES. This result is then transformed into the standard numeric score in QSSTRESN and a character representation of the standard numeric score in QSSTRESC.

The table represents the items from the ANSD V1.0 form as
instrument as well as the total score. Rows 8-14 show the subject was not evaluated on this instrument at visit 1. Because the reason for not completing the visit was not collected, no date is assumed for when the visit would have occurred.
