Practically, I've found works by Preacher, K and Hayes, A invaluable, and you can find them on Facebook (moderation and mediation group) and through their own individual webpages.
If you come up with other useful resources it would be good to hear about them

Subject: Mediating moderation, moderated mediation
Hi everyone,
I'm looking at performing some moderated mediations, and mediated moderations, in my regression analyses prior to building an SEM model. Although I am getting my head round the basic conceptual distinctions between these 2 types of analyses, I'm having trouble translating them into the actual equations ( + therefore SPSS commands) I need to do. Which I guess means that it's still not entirely clear in my head otherwise I would find it easy! My supervisor hasn't done these before either so she is taking a crack at it but recommended I see if anyone has actually used the techniques. I have only found one paper explaining a method, Muller Judd and Yezerbyt 2005, which is very helpful but the way they do their mediation is slightly different from Baron & Kenny's method -- so when they explain equations 4,5, and 6 I follow them until equation 6 at which point I get confused. DavidKenny.net also has a basic definition of these techniques, but I think I am not as natural a statistician as David Kenny!
Has anyone here used these techniques? Know of good resources/papers? Can explain how to carry them out? I'm nearly there but it's not quite clicking...
Thanks,
Rebecca
