Application of structural equation model on validity assessment of the evaluation indicator system

Abstract

Objective To explore the application of the Structure Equation Model on validity assessment of the evaluation indicator system,we studied Medical Capital Development Fund projects in 2007 to evaluate their construct validity.Methods Part of the evaluation results (1200 items) were divided into two parts randomly.PART1 was used for Exploratory Factor Analysis (EFA) to explore the Indicator System' structure,and formed model F1.Confirmatory Factor Analysis (CFA) was used to assess the construct validity of model F1.With considerations of Modification Index(MI) and reality,F1 was modified into F3.At last,we take PART2 as the sample to confirm F3.Result The results of model F3 fit indices showed a better fit.All the path coefficients,estimated load factors and other parameters were statistically significant.Conclusion Structural Equation Model is professional,reliable and satisfactory for the evaluation of indicator system's contract validity.
