住民健診を対象とした短縮版MMSE（SMMSE）の有用性と妥当性

抄録

The aim of the study was to investigate usefulness and validity of the short form of the Mini-Mental State Examination (SMMSE). Data were obtained from a large cohort study. Participants were 1684 community dwellers in a rural town (their age ranged from 40 to 94 years old). The SMMSE score was built from orientations of time, six memory items, serial 7's, a 3-stage command and a copy of a pair of intersecting pentagon. The receiver operating characteristic curve showed an area under the curve of 0.98. The cut-off between the sensitivity and the specificity of the SMME score for screening dementia was 24. The sensitivity was 84.3 %, the specificity was 91.9 %, the positive predictive value was 66.0 % and the negative predictive value was 99.2 % in SMMSE. The short form of the Mini-Mental State Examination was good screening test for dementia in older individuals.
