一类是所涉及的变量(因变量、自变量和调节变量)都是可以直接观测的显变量(observable variable) ,另一类是所涉及的变量中至少有一个是潜变量( latent variable) 。 1 显变量的调节效应分析方法 调节效应分析方法根据自变量和调节变量的测量级别而定。变量可分为两类, 一类是类别变量( categoricalvariable) ,包括定类和
A mediating variable (or mediator) explains the process through which two variables are related, while a moderating variable (or moderator) affects the strength and direction of that relationship. Including mediators and moderators in your research helps you go beyond studying a simple relationship ...
为伪变量(dummyvariable),用带有乘积项的回归模型,做层次回归分析。需要说明的是, 除非已知X和M不相关(即相关系数为零),否则调节效应模型不能看标准化解。这是因为, 即使X和M的均值都是零,XM的均值一般说来也不是零。(略) 调节变量是上个星期统计课老师讲过的问题,但是当时我还没有弄清楚,在经过一个星期的...
of variance (ANOVA) terms, a moderator effect can be represented as an interaction between a major independent variable and a factor that specifies the appropriate conditions for its operation, that is, the effect of the major independent variable depends upon the value of the moderator variable....
下午听Frau Jau讲Moderator- und Mediatorvariablen, 晚上回来看了Baron & Kenny那篇长文。 一上来没说Moderator- und Mediatorvariablen, 只说two functions of third variables. two often-confused functions of third variables: (a) the moderator function of third variables, which partitions a focal indepen...
the moderator variable be uncorrelated with both the predictor and the criterion (the dependent variable) to provide a clearly interpretable interaction term. Another property of the moder- ator variable apparent from Figure 1 is that, unlike the media- tor-predictor relation (where the predic...

In this article, we attempt to distinguish between the properties of moderator and mediator variables at a number of levels. First, we seek to make theorists and researchers aware of the importance of not using the terms moderator and mediator interchangeably by carefully elaborating, both conceptual...

Using such an approach, the essential properties of a moderator variable are summarized in Figure 1. The model diagrammed in Figure 1 has three causal paths that feed into the outcome variable of task performance: the THE MODERATOR-MEDIATOR DISTINCTION tor is a continuous variable and the ...
