Description
Objective: To validate a brief cognitive function examination (BCFE) by defining cutoff points, and analyzing sensitivity and specificity. Methods: The concurrent and discriminant validity of the BCFE were evaluated in 135 participants (aged ≥ 65 years) between 2007 and 2010. We derived optimal cutoff scores for sensitivity and specificity criteria for cognitive impairment. Results: BCFE scores were significantly correlated with full Mini-Mental State Examination (MMSE) scores (r = .938, p < .05) and scores on the Hasegawa Dementia Scale-Revised (r = .638, p < .05), indicating high concurrent validity of the BCFE. The BCFE scores differed significantly between Clinical Dementia Rating Scale (CDR) 0.0 and 0.5 groups (p < .05). The optimal cutoff score was 7/8, with sensitivity and specificity of 92.0% and 78.3%, respectively. Conclusions: The BCFE may be useful for detection of cognitive impairment in community-dwelling older adults in Japan.
