Scientific Validity

Scientific Validity

All NewMetrica instruments are developed using well established psychometric methodology, recognised as the gold standard for design of instruments to measure human pain and  health-related quality of life.

That process includes testing for validity and reliability as well as responsiveness where instruments are used to measure clinical change over time.  Changing the  presentation of the instrument by translating it into another language,  requires further linguistic and cultural validation and this has been carried out for the acute pain tools in a variety of languages.

Psychometric instrument design is an iterative process in which instruments are refined and re-tested with new populations in new contexts and for new purposes. This is the focus of our ongoing research

An established, peer-reviewed publication record highlighting scientific validity, reliability and responsiveness for all NewMetrica instruments can be accessed at (ADD LINK).
