The RUDAS is a short multicultural cognitive screening instrument designed to minimise the effects of cultural learning and language diversity on the assessment of baseline cognitive performance.
Some translated versions are available but not validated. The RUDAS can easily be administered with an interpreter and has good psychometric properties. The RUDAS has less cultural and educational bias so it is easily interpreted by an interpreter during an assessment.
