Multilevel Mediation Based on Hierarchical Linear Model
基于阶层线性理论的多层级中介效应

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 effec...
