Objective To evaluate the reliability and validity of the revised Turkish version of Mini Mental State Examination (rMMSE‐T) in educated and uneducated community‐dwelling elderly, to re‐organize the present Turkish version of MMSE and to determine cut‐off point of the revised test. Methods This cross‐sectional and analytical study involved totally 490 elderly subjects selected by cluster sampling method. Receiver operating characteristic (ROC) analysis, kappa analysis and Cronbach's α coefficients were used for statistical analysis. Results Areas under ROC curve in educated and uneducated elderly were found as 0.953 and 0.907. Cut‐off point of 22/23 of rMMSE‐T in educated elderly had the highest sensitivity (90.9), specificity (97.0) and positive likelihood ratio (30.3), whereas cut‐off point of 18/19 of the test in uneducated elderly had the highest sensitivity (82.7), specificity (92.3) and positive likelihood ratio (10.7). The Cronbach's α values of the rMMSE‐T for educated and uneducated elderly were higher than 0.7 (sign of good internal consistency of the test). A significant correlations between intrarater and interrater test–retest in educated elderly subjects were observed (0.966 (p = 0.000); 0.855 (p = 0.000), respectively), and also in uneducated elderly (0.988 (p = 0.000); 0.934 (p = 0.000), respectively). Kappa value of the test in educated and uneducated elderly showed a perfect agreement interraters (1.000) and a substantial agreement in intraraters (1.000, 0.784; 0.826, 0.656, respectively). Conclusion rMMSE‐T had a high reliability and validity. It will be more appropriate to use the revised test and the new cut‐off point for the diagnosis and screening of dementia among community‐dwelling Turkish elderly population.
