中文摘要：

在心理和教育研究中,经常遇到调节和中介效应。模型包含不止3个变量时,可能同时包含调节和中介变量,一种常见的模型是有中介的调节模型。本文评介了文献上可以找到的五种检验有中介的调节模型的方法,逐一甄别,指出其中一些不合理之处,并推荐较好的方法。整合其中主要方法,总结出检验有中介的调节模型的流程,用偏差校正的百分位Bootstrap法或马尔科夫链蒙特卡罗法检验其中的中介效应,并用一个实际例子演示如何用此流程检验有中介的调节模型。

英文摘要：

Moderation and mediation are frequently used in the research of psychology and behavior.Moderation occurs when the effect of an independent variable on a dependent variable varies according to the level of a third variable,termed as moderator,which interacts with the independent variable.Moderation focuses on factors that influence the strength and/or direction of the relation between the independent variable and dependent variable.Mediation indicates that the effect of an independent variable on a dependent variable is transmitted through a third variable,which is called mediator.Mediation addresses how that effect is produced.It is not uncommon for hypotheses about moderation and mediation relationships to occur in the same context.Models in which interaction effects are hypothesized to be mediated are appearing with increasing frequency.When a moderating effect is transmitted through a mediator,the effect is termed mediated moderation and the model is mediated moderator model.For example,stressful life events moderated the effect of sensation seeking on tobacco and alcohol use,and this moderation effect is mediated by affiliation with deviant peers.There are at least five methods for testing mediated moderation models.But some of the methods are difficult to be understood and explained.After discussing the merits and demerits of different methods,we propose a procedure for testing mediated moderation models.The newly proposed procedure is likely to be better than any single testing method in terms of the sum of type 1 and type 2 error rates.The procedure is summarized as below：（1） Regress Y on X,U,and UX.A significant coefficient（c3） associated with UX implies that U is the moderator of the relation between Y and X.Stop if the coefficient（c3） associated with UX is not significant.（2） Regress W on X,U,and UX.Regress Y on X,U,W,UX and UW.The moderated effect of U on the relation between Y and X is mediated by W if the coefficient（a3） from UX to W and the coefficient（b1） from W to Y are
