| 目的：编制一个适合我国老年人的老年性痴呆评定软件。方法：①参考简易智能精神状态检查量表（MMSE）及Demtect等老年性痴呆评价工具，建立老年性痴呆康复评定系统初始量表，制成软件（简称初始量表）量表考评。应用初始量表对杭州市区范围内的294例老年人进行测试，应用测试结果对量表进行信度、效度检验并与MESS量表比较。结果：初始量表Cronbach’s α系数为0.618，Spearman Brown分半信度为0.797，重测信度中单个测量ICC为0.247，平均测量ICC为0.798，表明量表具有较好的信度；运用具有Kaiser标准化的正交旋转法加以旋转，KMO指数为0.798，Bartlett 球形检验统计量χ2为437.518（P<0.01），说明变量间密切相关，数据适合进行因子分析。因素分析表明，老年性痴呆早期筛选包括2个因子，总体方差64.531%，表明结构效度较高。与MESS量表比较，初始量表灵敏度较高，两两比较差异有统计学意义（P=0.046<0.05）。结论：本文的初始量表的信度、效度指标较好, 可为我国老年性痴呆早期筛选的研究提供有效评价工具。 |

| Objective: To design and make an evaluation software for Alzheimer's Disease in Chinese old people. Methods：An initial evaluation scale was formed and a software was made. 294 old people in Hangzhou were tested by the evaluation software. The reliability and validity were tested. A contrast study with MESS scale was made. Results：The results showed Cronbach α coefficient of the scale was 0.618, Spearman-Brown split coefficient was 0.797, single Measure ICC was 0.247 and average Measure ICC was 0.798, which revealed that the scale had high reliability. By using orthogonal rotation with Kaiser standardized method to be rotated, KMO index was 0.798, and Bartlett test of sphericity statistic χ2=437.518, significant at the 0.000 level, indicating that variables were closely related, and data were suitable for factor analysis. Factor analysis results indicated that the scale included two factors, and the two factors could explain 64.531% of total scale variances, which showed high construct validity. The contrast study showed that the software had higher sensitivity than the MESS scale, P=0.046<0.05. Conclusion：The evaluation software for Alzheimer's disease has a high reliability and validity, and it may be used as an effective test instrument for Chinese old people. |
