Objectives To evaluate the effectiveness of the Chinese version of the Montreal Cognitive Assessment Basic (Mo CA ‐ BC ) as a screening tool for detecting mild cognitive impairment ( MCI ) in Chinese elderly adults. Design Cross‐sectional. Setting Huashan Hospital, Shanghai, China. Participants Individuals with MCI (n = 264) and mild Alzheimer's disease ( AD ) (n = 160) were recruited from the Memory Clinic, Huashan Hospital; cognitively normal controls were recruited from Jinshan Community, Shanghai, China (n = 280). Measurements Mo CA ‐ BC scores. Results The Mo CA ‐ BC had good criterion‐related validity (Pearson correlation coefficient Mo CA ‐ BC vs MMSE = 0.787) and reliable internal consistency (Cronbach alpha = 0.807). The optimal cutoff scores for MCI screening were 19 for individuals with no more than 6 years of education, 22 for individuals with 7 to 12 years of education, and 24 for individuals with more than 12 years of education. The Mo CA ‐ BC was superior to the MMSE for detecting MCI , with optimal sensitivity and specificity across all education groups using the above cutoff scores. Conclusion The Mo CA ‐ BC is a reliable cognitive screening test across all education levels in Chinese elderly adults, with high acceptance and good reliability.
