Three meta-analyses, 1 for each type of mediation, were conducted on a total of 57 studies. We now show how to conduct path analysis using several examples. Unlike normal mediation analysis you don't have to show the IVpredicts the DV in Block 1 but you still need to show the IV predicts the suppressor and there is a sig indirect effect of IV -> DV via the suppressor. I have a binary DV, a binary IV, and groups of mediators that consist of categorical, continuous, and dichotomous variables. The statistical significance of the indirect effect should be tested using bootstrapping (see Hayes [2013], Introduction to mediation, moderation, and conditional process analysis ). Moderation analysis in the behavioral sciences involves the use of linear multiple regression analysis or causal modelling. This is an example of a one-tail t-test as opposed to a two-tailed t-test outlined above.
