中文摘要：

在心理和其他社科研究领域，经常遇到中介和调节变量。模型的变量多于3个时，可能同时包含中介和调节变量，一种常见的模型是有调节的中介模型。本文检视文献上各种检验有调节的中介模型的方法，理清方法之间是竞争关系（分清优劣）还是替补关系（分清先后），在此基础上总结出检验有调节的中介模型的步骤，并用一个实例进行演示。文中也讨论了有调节的中介模型与有中介的调节模型的联系与区别。

英文摘要：

Mediation and moderation models are frequently used in the research of psychology and many other social science disciplines. Mediation indicates that the effect of an independent variable on a dependent variable is transmitted through a third variable, namely a mediator. For example, students’ gratitude promoted their academic achievement medially by increasing everyday academic resilience. Moderation occurs when the effect of an independent variable on a dependent variable varies according to the level of a third variable, which interacts with the independent variable. For instance, adolescents’ perceptions of their teachers’ authoritative teaching moderated the effect of antisocial disruption on peer acceptance. It is not uncommon for hypotheses about moderation and mediation relationships to occur in the same context where more than three variables are involved. When a mediation effect is moderated by a moderator, the effect is termed moderated mediation and the model is moderated mediation model. For example, everyday academic resilience acts as a mediator between gratitude and academic achievement, and this mediation process is moderated by stressful life events. There are several methods for testing moderated mediation models. The moderated mediation models being used for proposed testing methods are different. We are wondering whether different testing methods are competitors, or some of them are only backups. We discussed the different testing methods based on the most general type of model. The traditional testing method is the moderated causal steps approach, in which the regression coefficients are tested in sequence. Modern methods include the testing of the products of coefficients by using Bootstrap method or MCMC method, and testing of the difference between the maximum and minimum of the mediation effects. On the basis of the previous studies it can be summarized that the power of test with the moderated causal steps approach is the lowest among the three testing methods, whereas the test
