Summary Mini Mental State Examination - validation of new Danish version Ugeskr Læger 2008;170(9):745-749 Introduction: The Mini Mental State Examination (MMSE) is widely used in Denmark, but often in non-validated versions. In 2000 a cross-sectional workgroup decided on a new common version of the MMSE with a corresponding manual, which is validated for the first time in the present study. Materials and methods: The study was performed from April 2003 until August 2005 in four psychogeriatric departments. The participants (65+ years) were assessed on three consecutive occasions (week 0, 1 and 26) with the MMSE (nurse), and global scales as well as diagnostically with ICD-10 (psycho-geriatrician). Results: 101 persons were included, 29 were healthy, non-demented. 82 participants were assessed at visit two, 90 at visit three, but only 88 ratings were useable. The best cut-off value for the MMSE was ≥26. Inter-rater and test-retest (r=0.91) correlations of the MMSE were high as were the correlations to the global scales. However, there were considerable variations in mean score (±SD) as well as median score and range in relation to CGI and GDS values. The MMSE score is independent of sex and educational level. Conclusion: The MMSE also proved to be a robust scale in the present Danish version. It achieved excellent inter-rater and test-retest reliability. A cut-off value of = 26 proved better than 24 which was preferred hitherto. However, the ranges of the MMSE scores are so dispersed within the same global degree of severity that the MMSE should not generally be used to describe the severity of dementia disorders.
