Two conversion scales for determining equivalent scores on the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessement (MoCA) have been validated for Korean patients with Parkinson’s disease (PD). The aim of the present study was to validate these conversion scales for all patients with cognitive impairments regardless of dementia subtype.
 The medical records of 323 subjects who completed both MMSE and MoCA on the same day were retrospectively reviewed. The mean, median, and root mean squared error (RMSE) of the difference between the true and equivalent MMSE scores were calculated. Additionally, intraclass correlation coefficients (ICCs) between the true and equivalent MMSE scores were calculated, and the validity of the MoCA-MMSE conversion scales were evaluated according to educational level (low educated: ≤ 6 years; high educated: ≥ 7 years) and subtypes of cognitive impairment.
The difference between the true and equivalent MMSE scores had a median value of 0, mean values of 0.19 according to the van Steenoven scale and of 0.57 according to the Lawton scale, and RMSE values of 2.2 according to the van Steenoven scale and of 0.42 according to the Lawton scale. Additionally, the ICCs between the true and equivalent MMSE were 0.92 and 0.90 on the van Steenovan and Lawton conversion scales, respectively. These results were maintained in the subgroup analyses.
The present findings suggest that both van Steenovan and Lawton MoCA-MMSE conversion scales were applicable to transforming MoCA scores into MMSE scores in patients with cognitive impairments, regardless of dementia subtype and educational level.
