This study aimed to develop a conversion table for the Japanese version of the Montreal Cognitive Assessment (MoCA-J) to the Japanese version of the Mini-Mental State Examination (MMSE-J) to facilitate prediction of the MMSE-J score from the MoCA-J score. Participants (N = 121) were community-dwelling older adults (M = 74.12, SD = 4.73, age 61–84) who were able to visit the university laboratory alone, having no diagnosis of dementia. Their cognitive performance was assessed by MoCA-J and MMSE-J. We developed the MMSE-J conversion table from the row MoCA-J scores using the equipercentile equating with log-linear smoothing. A Bland-Altman plot displayed a nonsignificant systematic bias between the raw and converted MMSE scores. The conversion table presented high accuracy, with 85.8% of converted MMSE-J scores falling within two points of raw scores. In addition, our conversion table demonstrated the advantage of using the MoCA-J for early detection of cognitive decline.
