# TRR379 instrument item coding specifications
|
|
|
|
**The specifications are currently incomplete, see "survey" below**
|
|
|
|
This respository contains the specification for individual questionaire items
|
|
for all* instruments used for the Q01 cohort acquisition.
|
|
|
|
The coding for each instrument is located in a dedicated file under `instruments/`.
|
|
|
|
## Survey
|
|
|
|
The file `instrument_survey.tsv` collects information on instruments used at
|
|
particular TRR379 sites. It defines an authoritative mapping to homogenized
|
|
(TRR379-wide) identifiers for all instruments, and information about them.
|
|
|
|
This files has the following columns:
|
|
|
|
- `site-label`: a short label that is used at the particular site to refer to the instrument
|
|
- `site`: the site where an instrument is used. Adult (E) and children (K) are distinguished (e.g. FRA-K, AAC-E, ...)
|
|
- `same-as`: this column can be used to declare that an instrument used at a particular site is **exactly** identical to one used at another site. Use `site` and `site-label` to identify this identical instrument (e.g., `FRA-K:ARI`). If this column is filled, all following columns can be left out
|
|
- `id`: the homogenized, TRR379-wide identifier for this instrument (version)
|
|
- `title`: the full title of this instrument
|
|
- `identifying-info`: any free-text information that helps to precisely identify an instrument. Ideally this is one of (in order of preference): an ISBN of the official questionnaire, a DOI of an associated publication on the instrument, a URL to an online resource on the instrument, an author name. In case online a part of the full instrument is used, or it has been modified from the official version (translation, implementation of a paper/pencil test in an electronic system, etc), some version identifier/information needs to be provided in addition.
