Topic: Risk, prevention and care in population studies
Objective Reliability and validity of the Mini Mental State Examination in differentiating mild dementia from normal controls in Turkish population. Method The Standardized Mini Mental State Examination (SMMSE) and its instruction were translated into Turkish. A total of 212 subjects with mean age of 77 +/- 6, were recruited for the study. 71 were diagnosed to be demented and 141 were evaluated as normal controls. The scale total score was analysed for discriminant validity using Student's t-test. Sensitivity, specificity, positive and negative predictive values and kappa score were calculated for all of the scores between 18 and 29. Kappa value was calculated for the comparison of the dementia diagnosis between the two investigators using the best cut off score obtained in the analysis above. Results Statistical analysis revealed that the Turkish version of the SMMSE has high discriminant validity and interrater reliability in the diagnosis of mild dementia. The cut off score 23/24 was found to have the highest sensitivity (0.91), specificity (0.95), positive and negative predictive values (0.90 and 0.95) and kappa score (0.86). Interrater reliability analysis showed high correlation (r:0.99) and kappa value (0.92). Conclusion The results of this study showed that the Turkish version of the SMMSE has high reliability and validity for the diagnosis of mild dementia in Turkish population.
Key findings
- Results Statistical analysis revealed that the Turkish version of the SMMSE has high discriminant validity and interrater reliability in the diagnosis of mild dementia.
- Conclusion The results of this study showed that the Turkish version of the SMMSE has high reliability and validity for the diagnosis of mild dementia in Turkish population.
Why it matters
This study found the Turkish version of the Standardized Mini Mental State Examination had high reliability and validity for diagnosing mild dementia. It concerns a diagnostic test, not treating, curing, or preventing dementia.

How this study scored 45/100
Published in a peer-reviewed journal. Scored zero for study design, effect reported and randomised / blinded because the record does not state it. We have no data on journal's citation record, impact for its field and year and senior author's track record, so those were left out: it earned 39 of the 86 points we could judge it on, which is 45 out of 100.
