儿童用品中吸入性化学应激源限量社会经济分析方法效度评估——以地垫甲酰胺为例

摘要：

【目的】针对儿童用品中吸入性化学应激源限量社会经济分析方法构建了一套探索性的效度评估框架与方法，并以儿童地垫甲酰胺限量为例进行了初步验证。【方法】基于内容效度、结构效度、关联效度三维通用效度构建方法，搭建效度验证框架，通过内容效度指数、验证性因子分析、方差分析效应量求得相应的效度，并采用算术平均法合成综合效度。【结果】以儿童地垫中甲酰胺限量评价方法为评估对象，测评结果显示，该评价方法的内容效度指数为0.954，结构效度得分为0.873，关联效度效应量η2为0.994。依据算术平均法，得到综合效度为94.03%（≥90%），等级为“优秀”。【结论】本研究构建的三维效度验证框架具有可操作性，为儿童用品中吸入性化学应激源限量社会经济分析方法的科学性评估提供了探索性工具，有助于推动相关决策向更规范、更科学的方向发展。

Abstract:

[Objective] An exploratory validity evaluation framework and method for the socioeconomic analysis of the limit of inhaled chemical stressors in children’s products was constructed, and a preliminary verification was conducted taking the limit of formamide in children’s floor mats as an example. [Methods] A validity verification framework was constructed based on three dimensions: content validity, construct validity, and criterion validity.Corresponding validity indices were calculated using the content validity index, confirmatory factor analysis, and effect size from analysis of variance, and the arithmetic mean method was applied for comprehensive validity synthesis. [Results] Using the limit evaluation of formamide in children’s floor mats as the assessment case, the results showed that the content validity index of the evaluation method was 0.954, the construct validity score was 0.873, and the effect size η² for criterion validity was 0.994. Based on the arithmetic mean method, the comprehensive validity score is 94.03% (≥90%), which is rated as "excellent". [Conclusion] The three-dimensional validity verification framework constructed in this study is highly operational. It provides an exploratory tool for the scientific evaluation of socioeconomic analysis methods for limit values of inhalable chemical stressors in children’s products, thereby promoting more standardized and scientific policy-making.
