When the instrument is openly available, the Inventory column “Instrument availability” will say “Repository”. You will be able to find the full version of that instrument in one of the separate components, i.e. folders, connected with the Repository.

When the instrument is not openly available, you may contact the author via the provided email address to obtain the full version of the instrument.


All of the instruments are stored as both PDF and ODT files. ODT is similar to the DOCX format and can be opened by multiple programs such as Microsoft Word, OpenOffice Writer or LibreOffice Writer.

Scoring and recoding code is also available for some of the instruments (e.g. as an SPSS syntax file or R script).
