Abstract

Objective

To establish the norms of the Hong Kong Brief Cognitive Test (HKBC) among Chinese older adults and to examine its utility for differentiating neurocognitive disorders from cognitively normal controls.

Methods

Two thousand three hundred twelve participants aged 40 years and above were recruited from six regions of China as the norm construction sample. 93 normal participants and 246 cognitive impairment patients were included for diagnostic test of HKBC. Based on the multinomial regression model, which analyzed the relationship between HKBC score and demographic information, the norm of HKBC score and converted T score (HKBC-T) were constructed. The ROC curve of HKBC-T was depicted to calculate the optimal cutoff value of screening cognitive impairment.

Results

The results showed that HKBC score was negatively correlated with age (SE = −5.48, p < 0.001) and positive correlation with education (SE = 1.53, p < 0.001), with no significant association with gender and living area. The AUC value of HKBC-T is 0.85 in distinguishing cognitive impairment and normal older adults. The optimal cutoff value was 45.79 points, achieving a sensitivity of 91.4% and a specificity of 66.7%.

Conclusion

Age and education must be adjusted when creating the HKBC norms. The HKBC-T is promising in detecting cognitive impairment at the population level.

目的在中国老年人中建立香港简易认知测验（HKBC）的常模，并研究其在区分神经认知障碍和认知正常对照组方面的作用。方法从中国六个地区招募了 2312 名 40 岁及以上的参与者作为常模构建样本。其中，93 名正常人和 246 名认知障碍患者被纳入 HKBC 诊断测试。基于多项式回归模型分析了 HKBC 评分与人口统计学信息之间的关系，构建了 HKBC 评分和转换后 T 评分（HKBC-T）的常模。绘制了 HKBC-T 的 ROC 曲线，以计算筛查认知障碍的最佳临界值。结果表明，HKBC 评分与年龄呈负相关（SE = -5.48，p < 0.001），与教育程度呈正相关（SE = 1.53，p < 0.001），与性别和居住地区无明显关系。HKBC-T 在区分认知障碍和正常老年人方面的 AUC 值为 0.85。最佳临界值为 45.79 分，灵敏度为 91.4%，特异度为 66.7%。结论在制定香港口腔健康测试标准时，必须对年龄和教育程度进行调整。HKBC-T在检测人群认知障碍方面具有良好的前景。

期刊介绍： The rapidly increasing world population of aged people has led to a growing need to focus attention on the problems of mental disorder in late life. The aim of the Journal is to communicate the results of original research in the causes, treatment and care of all forms of mental disorder which affect the elderly. The Journal is of interest to psychiatrists, psychologists, social scientists, nurses and others engaged in therapeutic professions, together with general neurobiological researchers. The Journal provides an international perspective on the important issue of geriatric psychiatry, and contributions are published from countries throughout the world. Topics covered include epidemiology of mental disorders in old age, clinical aetiological research, post-mortem pathological and neurochemical studies, treatment trials and evaluation of geriatric psychiatry services.
