目的探讨结构方程模型在评价指标体系结构效度中的应用,并以2007年度首发基金立项函评指标体系为例,评价其结构效度.方法随机将部分评审结果共1200项分为PART1与PART2两部分.PART1用于探索性因子分析以探索指标体系的结构,形成模型F1,并利用结构方程模型中的测量模型验证F1的结构效度.然后将修正系数与实际联合分析,将模型F1修正为模型F3.最后对PART2用验证性因子分析评价模型F3的结构效度.结果最终模型F3的拟合指数结果显示模型的拟合优度较好.所有的路径系数、载荷系数及其他参数估计均有统计学意义.结论结构方程模型是一种充分考虑专业理论、可靠的分析方法.它通过分析比较,选出相对满意的因子结构方案,从而为研究提供合理的理论依据和专业结论.在评价指标体系结构效度的研究中引入结构方程模型具有很重要的现实意义.

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.
