摘要： 本文介绍了三种常见的多层级中介效应模型, 并根据阶层线性理论和依次检验回归系数的方法, 详述了多层级中介效应的检验步骤以及中介效应量的估计方法, 在2-1-1和1-1-1中介效应模型中, 推荐采用对层1自变量按组均值中心化, 同时将组均值置于层2截距方程式的中心化方法, 以实现组间和组内中介效应的有效分离。本文还展望了多层级中介效应模型的拓展方向, 即多层级调节性中介模型和多层级结构方程模型; 以及检验方法的拓展, 即Sobel检验和置信区间检验。

Abstract: This article described three common multilevel mediation models. According to hierarchical linear model and causal steps approach, inspection procedures of multilevel mediation effect and method of estimating mediation effect size were elaborated. Group mean centering with the means reintroduced into the level-2 intercept model would provide an appropriate test of 2-1-1 and 1-1-1 mediation model, because this centering method could decompose multilevel mediation effects into within-group and between-group effects. This article also discussed the future direction of multilevel mediation model, which is multilevel moderated mediation and Multilevel Structural Equations Modeling, and the extension of testing methods, namely, Sobel test and confidence interval testing method.

Key words: multilevel, mediation, hierarchical linear model, centering
