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.
