Association between the Brief Cognitive Checklist and the Screening Test for Mild Cognitive Impairment in Older Adults in the Community-dwelling

Abstract

We developed the Brief Checklist of Cognitive Functioning(BCCL), a dichotomous self-administered questionnaire with six cognitive domains. The purpose of this study was to analyze the relationship between the BCCL, a new cognitive function screening index; and the Japanese version of the Montreal Cognitive Assessment(MoCA-J), a common mild cognitive impairment(MCI) screening index. The participants were 268 older adults in urban community-dwelling, aged 65 years or older. The assessment items included basic characteristics, BCCL, and MoCA-J. In all participants and early older adults, a significant correlation between MoCA-J total score and BCCL total score was found using partial correlation analysis with age and polypharmacy as adjustment variables. MCI was found in 71.4% of participants with a BCCL score of 3 or higher, which was significantly higher than in participants with a BCCL score of 2 or less, and the same was true in early older adults. The BCCL is particularly helpful as a screening index of cognitive function in early older adults.
