AIM: The Mini-Mental State Examination is a widely used cognitive assessment tool. However, it has several limitations, including the learning effect and interrater reliability. Therefore, we developed a Computer-Based Cognitive Assessment Tool (CompBased-CAT), which runs on a tablet or personal computer. In this study, we examined the validity and discrimination ability of the CompBased-CAT.
METHODS: Participants were recruited from the Otasha-Kenshin study carried out in 2016. We included 773 community-dwelling older individuals in Japan (332 men, 441 women, aged 65-97 years). CompBased-CAT scores were converted to z-scores, and the correlation with Mini-Mental State Examination scores was examined using Pearson's correlation coefficient. Furthermore, the ability to discern cognitive impairment was examined using the receiver operating characteristic curve.
RESULTS: The Pearson's correlation coefficient for the Mini-Mental State Examination scores and each task component of the CompBased-CAT ranged from 0.24 to 0.41 (P < 0.001), and the correlation coefficient of the total z-scores was 0.51 (P < 0.001). The sensitivity, specificity and area under the receiver operating characteristic curve of the discriminating ability of the CompBased-CATool for cognitive impairment were 0.81, 0.77 and 0.85, respectively.
CONCLUSIONS: The CompBased-CAT certainly possesses validity, discriminating ability and utility as a new cognitive assessment tool in community-dwelling older individuals. Geriatr Gerontol Int 2020; ••: ••-••.
