The construction, reliability & validity test, and norm establishment of geriatric comprehensive health evaluation system / 中华老年医学杂志

ABSTRACT

Objective:To construct a geriatric comprehensive health evaluation system, and establish the norm of corresponding score.Methods:The methods of Delphi survey was implemented to develop the geriatric comprehensive health evaluation system.The weight coefficients of the items were calculated and assigned according to the expert-graded importance score and Saaty analytic hierarchy process.Reliability and validity of the system were examined.Goodness of fit was evaluated by confirmatory factor analysis.The demarcation norm of geriatric comprehensive health score was established based on an empirical study of 2, 118 non-hospitalized elderly population.Results:During the process of Delphi expert consultation and item analysis, nine items were deleted and two items were added.In the end, the 29-item comprehensive geriatric health evaluation system was developed, which included three dimensions of physiology, psychology, as well as social support and environment.The Cronbach's α coefficient of the evaluation system was 0.709.The exploratory factor analysis-extracted ten common factors meet ten second-level items.Confirmatory factor analysis indicated that the goodness of fit of the system was good.Geriatric health status was divided into five grades of very poor, poor, general, good and excellent by 0.5 to 1 standard deviation.The demarcation norm of geriatric comprehensive health score for different age and gender was established accordingly.Conclusions:The reliability and validity of the geriatric comprehensive health evaluation system are satisfactory.The construction of comprehensive health evaluation system and the establishment of the norm can facilitate the quantitative assessment of geriatric health status, and provide a reference for the screening and grading of individual health status in the elderly.
