结构方程模型多组分析在应用语言学研究中的运用-- Amos 17.0 实例演示

The application of SEM Multiple-Group Analysis in applied linguistics research: An illustration with Amos 17.0

Amos 17.0 是进行结构方程模型（Structural Equation Modeling，SEM）分析的重要软件之一。随着对SEM 技术应用的深入，结构方程模型多组分析（Multiple-Group Analysis）也逐渐引起研究人员的重视。它通过考查调节变量的效应来深入地检验理论模型的稳定性，该方法既适合检验理论模型在调节变量不同水平上的拟合程度，也适合于检验跟踪数据与理论模型的拟合问题。笔者通过自己的一项研究实例，以Amos 17.0 软件为依托，介绍了结构方程模型多组分析技术的基本原理及其在应用语言学研究中的使用方法，旨在为国内应用语言学界有意使用该方法的人员提供可参考的研究范例。

SEM Multiple-Group Analysis can provide researchers with a means to study the stability of theoretical models by testing the effects of moderate variables. It is suitable not only for examining the goodness of fit between theoretical models and data on different levels of moderate variables but also for the goodness of fit between theoretical models and longitudinal data. This paper introduced the rationale and process of SEM Multiple-Group Analysis with the author's own research as an example for the researchers of applied linguistics in China who might apply this statistical technique in their studies.
