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 instrument is labeled a "Behavior Rating Scale" and not a "Withdrawal Scale" because subjects 1) are confused by filling out a “withdrawal” scale prior to cessation, and 2) will sometimes not report a symptom during abstinence if they do not believe it is due to withdrawal.

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.
