Structural equation modeling (SEM) is a multivariate technique suited for testing proposed relations between variables. In this article, the authors discuss the potential for SEM as a tool to advance health communication research both statistically and conceptually. Specifically, the authors discuss the advantages that latent variable modeling in SEM affords researchers by extracting measurement error. In addition, they argue that SEM is useful in understanding communication as a complex set of relations between variables. Moreover, the authors articulate the possibility for examining communication as an agent, mediator, and an outcome. Finally, they review the application of SEM to recursive models, interactions, and confirmatory factor analysis.
结构方程模型(SEM)是一种适用于检验变量间所提出关系的多变量技术。在本文中,作者探讨了SEM作为一种工具在统计学和概念上推进健康传播研究的潜力。具体而言,作者讨论了SEM中的潜在变量建模通过提取测量误差为研究人员带来的优势。此外,他们认为SEM有助于将传播理解为变量之间复杂的关系集。而且,作者阐述了将传播作为动因、中介和结果进行检验的可能性。最后,他们回顾了SEM在递归模型、交互作用和验证性因素分析中的应用。
