1 Introduction

This document describes the CDISC implementation of the Minnesota Tobacco Withdrawal Scale-Revised (MTWS-R) instrument.

There is no known standard case report form (CRF) available for this instrument. CDISC created this CRF to represent the instrument which CDISC believes is in the public domain. This is not an endorsement of the instrument. The creation of this instrument was based on published articles describing the instrument. Sponsors may create this instrument’s CRF using their style guidelines, but they need to maintain the wording and order of the questions/items and responses as described on the CRF. 

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

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

1.1 Representations and Warranties, Limitations of Liability, and Disclaimers

This document is a supplement to the SDTMIG for Human Clinical Trials and is covered under Appendix F of that document, which describes representations, warranties, limitations of liability, and disclaimers. Please see Appendix F of the SDTMIG for a complete version of this material.

CDISC specifies how to structure the data that has been collected in a database, not what should be collected or how to conduct clinical assessments or implement protocols. CDISC disclaims any liability for your use of this material.

2 Copyright Status

CDISC believes this instrument to be in the public domain, but you should perform your own assessment. CDISC has included the MTWS-R in the CDISC inventory of QRS data standards supplements. Hence, CDISC developed QSTESTCD and QSTEST for each item based on the text on the instrument. There may be many versions of this instrument. CDISC has chosen to use this version as the data standard.

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.

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 MTWS-R are listed below.

The MTWS-R evaluates the effects of smoking cessation. It is a 15-item self-report measure of tobacco withdrawal. Each item is rated on a 5-point ordinal scale (0="None", 1="Slight", 2="Mild", 3="Moderate", 4="Severe"). A total score, based on 8 of these items, between 0-32 is also captured.

  1. The original scores include a numeric rating (0-4) and a definition of what is represented by the rating (e.g., 0 = "None"). For the MTWS-R, QSORRES is populated with the text description while the numeric rating is represented in the standardized character and numeric result variables QSSTRESC and QSSTRESN.

  2. The time period of evaluation for the MTWS-R 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 MTWS-R is typically the last 24 hours (QSEVLINT = "-PT24H")

  3. Records are created in qs.xpt for every instrument item

    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.

    2. Due to the variability of the derived score generation process, records are not included for scores that are not provided.
  4. The MTWS-R instrument may include an overall score that is considered as captured data on the instrument and is not considered as derived in the example below. This overall score, or total withdrawal discomfort score, consists of the first eight symptoms (i.e., QSTESTCDs MTWSR101 through MTWSR108). This score may be submitted in SDTM or derived in the Analysis Data Model (ADaM) per scoring instructions from http://www.med.uvm.edu/behaviorandhealth/research/minnesota-tobacco-withdrawal-scale.

    1. The overall score is represented in QSORRES, QSSTRESC, and QSSTRESN.
    2. If the overall score is received or derived by the sponsor, it is recommended that it is submitted to SDTM and verified in ADaM whenever feasible. It is the sponsor's responsibility to do this verification based on the instrument's user manual or instructions from the owner.
  5. Terminology

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

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

3.2 Example for the MTWS-R QS Domain Model

The MTWS-R 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 MTWS-R instrument. The example uses CDISC Controlled Terminology for QSTESTCD, QSTEST, and QSCATAll 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.


The table represents the items from the MTWS-R instrument.

Rows 1-8:Show the eight well-validated, primary withdrawal symptom descriptors (single items) based on DSM-5 (QSTESTCDs MTWSR101 through MTWSR108).
Rows 9-15:Show the seven additional symptom candidates (e.g., “Craving to smoke;” “Constipation;” and “Dizziness”).
Row 16:Shows the total withdrawal discomfort score is calculated from the first eight symptoms.
Rows 17-32:Show the subject was not evaluated on this instrument at visit 2. Since the reason for not completing the visit was collected, the date is included in QSDTC for when the visit was planned.

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.

The controlled response terminology for the tests below is named MTWSR101T15OR for the variable QSORRES and MTWSR101T15STR for the variables QSSTRESN and QSSTRESC.
