| Abstract: | The concepts of mediator, moderator and covariate variables were discussed, and approaches in estimation and testing of mediating, moderating and covariate effects were summarized with recommendations for applications. Subsequently, three kinds of variables as well as their effects were compared in terms of their measuring levels, testing methods and other facets which enabled a better understanding of the variables involved. |
