Moderated mediation, also known as conditional indirect effects, [2] occurs when the treatment effect of an independent variable A on an outcome variable C via a mediator variable B differs depending on levels of a moderator variable D. Specifically, either the effect of A on B, and/or the effect of B on C depends on the level of D.
Simple mediation model. The independent variable causes the mediator variable; the mediator variable causes the dependent variable. In statistics, a mediation model seeks to identify and explain the mechanism or process that underlies an observed relationship between an independent variable and a dependent variable via the inclusion of a third hypothetical variable, known as a mediator ...
An example of conceptual moderation model with one categorical and one continuous independent variable. Cohen et al. (2003) recommended using the following to probe the simple effect of gender on the dependent variable ( Y ) at three levels of the continuous independent variable: high (one standard deviation above the mean), moderate (at the ...
Psychological statistics is application of formulas, theorems, numbers and laws to psychology. Statistical methods for psychology include development and application statistical theory and methods for modeling psychological data. These methods include psychometrics, factor analysis, experimental designs, and Bayesian statistics. The article ...
The Sobel test is basically a specialized t test that provides a method to determine whether the reduction in the effect of the independent variable, after including the mediator in the model, is a significant reduction and therefore whether the mediation effect is statistically significant.

The shares saying that he’ll bring change for the worse (20% now vs. 21% in 2016) or no change at all (31% now vs. 32% in 2016) are nearly identical to where they stood eight years ago.
The four alternative models of advertising attitude explain how antecedent variables related to advertising outcomes are mediated by attitude toward advertising. These models are named the affect transfer, dual mediation, reciprocal mediation, and independent influences hypotheses. Model 1. The affect transfer hypothesis (ATH).
