The Montreal Cognitive Assessment Chinese-Language Los Angeles version (MoCA-ChLA) was developed and administered during an in-home interview to 1,192 participants (mean age 62.5 years, mean education 11.6 years) in a population-based Chinese American Eye Study (CHES) in Los Angeles. The MoCA-ChLA score (mean ± SD) was 23.8 ± 4.2 with little ceiling and no floor effects. The score increased with higher education, decreased with advancing age, and was not related to gender. Compared to the education 1-6 years group, the mean MoCA-ChLA score was 2.6 and 4.6 higher in the education 7-11 and 12-20 years groups, respectively. The Mandarin- (n = 612) and Cantonese- (n = 612) speaking subgroups performed comparably; Cronbach's alpha of the MoCA-ChLA score was 0.78 and 0.79 for these two groups, respectively. Item response theory analysis showed good discriminating power for executive function and memory. These properties support the MoCA-ChLA as a useful screening tool for aging and dementia studies for Mandarin or Cantonese speakers.
蒙特利尔认知评估中文版洛杉矶版(MoCA - ChLA)是在洛杉矶一项基于人群的华裔美国人眼病研究(CHES)的上门访谈中开发并应用于1192名参与者(平均年龄62.5岁,平均受教育年限11.6年)。MoCA - ChLA得分(均值±标准差)为23.8±4.2,几乎没有天花板效应且无地板效应。得分随受教育程度提高而增加,随年龄增长而降低,与性别无关。与受教育1 - 6年组相比,受教育7 - 11年组和12 - 20年组的MoCA - ChLA平均得分分别高2.6分和4.6分。说普通话的亚组(n = 612)和说粤语的亚组(n = 612)表现相当;这两组的MoCA - ChLA得分的克朗巴哈系数分别为0.78和0.79。项目反应理论分析显示该量表对执行功能和记忆具有良好的区分能力。这些特性支持MoCA - ChLA作为说普通话或粤语人群衰老和痴呆症研究的有用筛查工具。
