Ok, you have two choices from this point. Or, you can take the short road and just get to the part where you actually do the analysis. This link takes you to the SPSS and Excel tools you can use to run your own mediation tests. I recommend at least looking over the stats, but who am I to tell you what to do? Mediation has been wonderfully described by David Kenny on his website, so I refer you there if you want a detailed description of the procedure. Statistically, mediation is calculated with three equations that are typically represented with the diagrams to the right. X is considered the causal variable, M is the mediator, and Y is the outcome.
The first is that the “b” coefficient is NOT simply the effect of M on Y. It is actually the effect of M on Y CONTROLLING for X. When you calculate the b coefficient, you need to put both the X and M variables in simultaneously. Doing this evaluates whether you meet Kenny’s “step 3” when testing mediation.
