Questionnaires, Ratings, and Scales (QRS)

The name of an instrument is represented --CAT and may be either abbreviations or longer names. Applicants will reference CDISC Controlled Terminology: 

• The QRS Naming Rules for --CAT, --TEST, and --TESTCD and the list of QRS instruments that have published CDISC Controlled Terminology with NCI/EVS are available at: https://www.cdisc.org/standards/terminology/controlled-terminology.
• Refer to the following CDISC Controlled Terminology codelists for QRS instrument --CAT terminology:
  
  • Category of Clinical Classification
  • Category of Functional Test
  • Category of Questionnaire
• QRS --TESTCD/--TEST terminology codelists are listed separately by instrument name.       

Names of subcategories for groups of items/questions are described under the --SCAT variable. --SCAT values are not included in the CDISC Controlled Terminology system but rather controlled as described in the QRS supplements in which they are used.

When numeric standardized responses assigned to text responses (e.g., mild, moderate, severe being 1, 2, 3) are documented in the QRS CRF instructions, a user manual, a website specific to the QRS instrument, or another reference document, the numeric responses will be represented in the tabulation dataset. This is irrespective of data collection (e.g., when a QRS CRF does not include numeric standardized responses for collected text).

Applicants will consult published QRS supplements for guidance on submitting derived information in a QRS domain. Derived variable results in QRS are usually considered captured data. If applicants operationally derive variable results in a new record, then this will be represented in --DRVFL.

The following rules apply for “total”-type scores in QRS datasets.

• QRS subtotal, total, etc. scores listed on the CRF are considered captured data and are included in the instrument’s controlled terminology.
• QRS subtotal, total, etc. scores not listed on the CRF but documented in an associated instrument manual or reference paper are considered captured data and are included in the instrument’s controlled terminology.
• QRS subtotal, total, etc. scores not listed on the CRF, but known to be included in eData by applicants are considered captured data and are included in the instrument’s controlled terminology. The QRS instrument’s controlled terminology is considered extensible for this case and the subtotal or total score should be requested to be added.
  
  • Any imputations/calculations done to numeric “standardized responses” to produce the total score via transforming numeric “standardized responses” are done as part of analysis.
• The QRS instrument subtotal or total score, which is the sum of the numeric responses for an instrument, is populated in --ORRES, --STRESC, and --STRESN. It is considered a captured subtotal or total score without any knowledge of the applicant data management processes related to the score.
  
  • If operationally derived by the applicant, it is the applicant's responsibility to set the --DRVFL flag based on their eCRF process to derive subtotal 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 applicant, 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.

The variable --REPNUM variable is populated when there are multiple repeats of the same question. When records are related to the first trial of the question, the variable --REPNUM should be set to "1". When records are related to the second trial of the same question, --REPNUM should be set to "2", and so forth.

The actual version number of an instrument is represented in the --CAT value as designated by the QRS Terminology Team. If it is determined that this is not the case for an instrument:

• Notify the QRS Terminology Team that the instrument has a specific or multiple version numbers. This team will assist in providing an resolution on how the situation will be handled.
• Consider the use of the --GRPID variable to indicate the instrument's version number prior to a decision by the QRS Terminology Team.
• The applicant is expected to provide information about the version used for each QRS instrument in the metadata (using the Comments column in the Define-XML document). This could be provided as value-level metadata for --CAT.
• The applicant is expected to provide information about the scoring rules in the metadata.

If needed, evaluators may be represented in SUPP-- datasets and variables --EVAL and --EVALID will not be used. 

Any identifiers, timing variables, or findings general observation class qualifiers may be added to a QRS domain, but the following qualifiers would generally not be used: --POS, --BODSYS, --ORNRLO, --ORNRHI, --STNRLO, --STNRHI, --STRNC, --NRIND, --XFN, --LOINC, --SPEC, --SPCCND, --LOC, --FAST, --TOX, --TOXGR, --SEV.
