Our aim was to compare the utility and accuracy of the Chinese Version of Montreal Cognitive Assessment Basic (MoCA-BC) and the Montreal Cognitive Assessment-Beijing Version (MoCA-BJ) in the identification of mild cognitive impairment (MCI) under different education levels. A sample of individuals with MCI (n = 295), Alzheimer's disease (AD; n = 254), and normal controls (NC; n = 259) at 2 Memory Clinics and communities was administered the MoCA-BC, MoCA-BJ, Mini-Mental State Examination (MMSE), and other neuropsychological tests. The discriminant validity of the MoCA-BC and MoCA-BJ as diagnostic instruments was ascertained. The overall discriminant validity for detection of MCI from NC (receiver operating characteristic area under the curve [95% confidence interval]) was that the MoCA-BC (0.95 [0.93, 0.97]) had better sensitivity and accuracy than MoCA-BJ (0.87 [0.84, 0.90]). In addition, we provide an easy to use table that enables the conversion of MoCA-BC to the MoCA-BJ scores or to MMSE scores. The MoCA-BC and MoCA-BJ provided good diagnostic accuracy when compared to MMSE. The MoCA-BC, which was proved to be an appropriate tool when screening for MCI among elderly subjects, can now be compared directly with the MoCA-BJ.
