OBJECTIVES
The purpose of the present article is to elucidate the opportunities provided by Rasch modelling in epidemiology and public health research in order to evaluate composite measures of health.
METHODS
The article gives a review of Rasch modelling in conjunction with illustrative examples based on adolescent survey data.
RESULTS
The article demonstrates how the Rasch-model enables examinations of the way items work across different samples/subgroups, e.g., detection of possible differential item functioning.
CONCLUSIONS
It is concluded that Rasch modelling may serve as a useful tool in the evaluation and the development of composite health measures intended to be used in epidemiology and public health research.
目的
本文旨在阐明拉施模型在流行病学和公共卫生研究中为评估综合健康指标所提供的机遇。
方法
本文结合基于青少年调查数据的示例对拉施模型进行综述。
结果
本文展示了拉施模型如何能够检验各项目在不同样本/亚组中的作用方式，例如，检测可能存在的项目功能差异。
结论
得出的结论是，拉施模型可作为一种有用工具，用于评估和开发旨在用于流行病学和公共卫生研究的综合健康指标。
