| 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. |
