This study aimed to verify the Chinese version of the Brief Assessment of Impaired Cognition Questionnaire (C-BASIC-Q), and provide a new tool for the future large-scale epidemiological investigation of cognitive function in China. From March to May 2021, a cross-sectional study of 2,144 Chinese community-dwelling older adults (men = 1,075, mean age = 72.01 years, = 6.96 years, ranging from 60-99 years) was conducted in Jinan. Exploratory and confirmatory factor analyses were performed to evaluate the factor structure of the C-BASIC-Q. Convergent validity was evaluated by correlations with the Mini-Mental State Examination (MMSE). Internal consistency and test-retest reliability were evaluated using Cronbach's alpha and retest correlations in a sub-sample ( = 129). Linear regression was used to analyze the impact of demographic factors on the MMSE and C-BASIC-Q scores. Measurement invariance was evaluated using a multi-group confirmatory factor analysis. The mean C-BASIC-Q score was 15.94 ( = 3.43). Factor analysis suggested a three-factor structure of C-BASIC-Q (self-report, orientation, and informant report). The C-BASIC-Q score was significantly positively associated with the MMSE score, showing good convergent validity. Cronbach's alpha of the C-BASIC-Q was 0.862, and the test-retest correlation coefficient was significant ( = 0.952, < 0.001), indicating good internal consistency and test-retest reliability. Measurement invariance analysis showed that C-BASIC-Q had configural, metric, and scalar invariance across sex, age, residence, education level and marital status. C-BASIC-Q was less affected by age, residence, education, and marital status than the MMSE. In summary, the C-BASIC-Q had good reliability, validity, and measurement invariance, and is a valid tool for evaluating cognitive functioning in Chinese community-dwelling older adults.
本研究旨在验证简体中文版Brief Assessment of Impaired Cognition Questionnaire（C-BASIC-Q），并为未来在中国进行大规模认知功能的流行病学调查提供新工具。2021 年 3 月至 5 月，在济南进行了一项针对 2144 名中国社区居住的老年人（男性=1075 人，平均年龄=72.01 岁，标准差=6.96 岁，年龄范围为 60-99 岁）的横断面研究。采用探索性和验证性因子分析评估 C-BASIC-Q 的因子结构。采用与简易精神状态检查（MMSE）的相关性评估收敛效度。在一个子样本中（n=129），采用 Cronbach's alpha 和重测相关性评估内部一致性和重测信度。采用线性回归分析人口统计学因素对 MMSE 和 C-BASIC-Q 评分的影响。采用多组验证性因子分析评估测量不变性。C-BASIC-Q 的平均得分为 15.94（标准差=3.43）。因子分析提示 C-BASIC-Q 具有三因子结构（自我报告、定向和知情者报告）。C-BASIC-Q 评分与 MMSE 评分呈显著正相关，表明具有良好的收敛效度。C-BASIC-Q 的 Cronbach's alpha 为 0.862，重测相关系数显著（=0.952，p<0.001），表明具有良好的内部一致性和重测信度。测量不变性分析表明，C-BASIC-Q 在性别、年龄、居住地、教育程度和婚姻状况方面具有构念、度量和标度不变性。与 MMSE 相比，C-BASIC-Q 受年龄、居住地、教育程度和婚姻状况的影响较小。综上所述，C-BASIC-Q 具有良好的信度、效度和测量不变性，是评估中国社区居住老年人认知功能的有效工具。
