[Reliability and validity of a newly developed tool to be used for the comprehensive geriatric assessment on community elderly].

OBJECTIVE:To evaluate the reliability and validity of a comprehensive geriatric assessment tool set for community elderly. METHODS:A sample of 574 community elderly (231 males, 343 females) aged 60 to 94 years, were included in the study. Split-half reliability and Chronbach' s α coefficient were used to test the reliability, with Face validity tested by Delphi method. Construct validity was tested, using the Factor Reliability. RESULTS:The split-half reliability coefficient appeared as 0.706. The Chronbach' s α coefficient was 0.652 for the whole questionnaire. The authority coefficient was 0.876, and the Kendall coefficient was 0.408 (P<0.001). Six factors were identified through factor analysis and the factor loading matrix showed that the construct validity was good. CONCLUSION:The tool was recognized as a reliable and validated measure for the comprehensive assessment on community elderly.
