Just a course in Mediation and Moderation analysis, and the use of the Process macro, with Amanda Montoya. Brilliant, in that it really explains how to use the tool, and how to interpret the results. Amanda is also a gifted instructor. 🙂
Here a few notes and resources from the course:
To fully understand moderation analysis, and how it influences the various variables, it is necessary to visualize it. Not all published papers do this, however, there are useful tools online to help with this, such as:
Two-Way Interaction Effects in MLR
This web page calculates simple intercepts and simple slopes, the region of significance, and computes specific values to facilitate the plotting of significant two-way interactions in ordinary least squares (OLS) regression. The interaction can be between two dichotomous variables, two continuous variables, or a dichotomous and a continuous variable.

PROCESS operates on both Windows and Mac versions of SPSS and SAS. PROCESS for SPSS requires SPSS version 19 or later but works best on versions 22 and above. PROCESS for SAS requires PROC IML. …
Montoya developed a macro, like the Hayes’ PROCESS for called MEMORE for Two instance repeated measure design. To download it, visit her page:

A weakness of Mediation and moderation analysis using PROCESS / OLS, is that it performs poorly for latent variables, which is very common in business and psychology. SEM performs far better for this. A recomended book for SEM is:
Regression And Mediation Analysis Using Mplus
The inspiration to write this book came from many years of teaching about Mplus and answering questions on Mplus Discussion and Mplus support. It became clear that once people leave school, it is difficult to keep up with the newest methodology.
Being possibly biased, as Hayes was Montoya’s phd supervisor, she strongly reccomends his books, both for regression analysis and mediation and Moderation
Regression Analysis and Linear Models, co-authored with Richard Darlington,
The 2nd edition of Introduction to Mediation, Moderation, and Conditional Process Analysis.
.. However, given the focus on pedagogic when teaching, I expect they are worth looking at!
There are tutorials on advances in methods online, such as in:
