Background: The Mini Nutritional Assessment (MNA®) is a well-known clinical scale that is often used for nutritional screening of older people in different settings recommended by several international clinical and scientific organizations. Aims: The aims of this article were: 1) to translate the MNA® from English to Norwegian and 2) to test the Norwegian version of the instrument for reliability and validity in a small sample of older nursing home patients. Methods: The English version of the MNA® was translated according to recommended procedures. A convenience sample of 26 older nursing home patients was screened with the MNA® by 10 registered nurses. Reliability and validity of the instrument were assessed. Results: Support for reliability and validity was shown in the study group. Conclusion: Positive support for sufficient quality of the Norwegian version of the MNA® was shown, but further testing of the instrument is needed.
