[5] Type 2 moderation, however, is more statistically difficult, so Langfred reviews three different possible approaches for the analysis, and ultimately recommends one of them as the correct technique.
Rather, because the model in the paper involved moderated mediation, a very large appendix was included, in which the definitions and procedures for the regression analysis were developed.
[1] In order to test for moderated mediation, some recommend examining a series of models, sometimes called a piecemeal approach, and looking at the overall pattern of results.
[1] This approach is similar to the Baron and Kenny method for testing mediation by analyzing a series of three regressions.
Bootstrapping has also been suggested as a method of estimating the sampling distributions of a moderated mediation model in order to generate confidence intervals.

Conceptual diagram of a moderated mediation process model where the independent variable (A) moderates its own indirect effect on the outcome variable (C) through the mediator (B) by moderating the effect of B on C.
Conceptual diagram of a moderated mediation process model in which one variable (D) moderates the relationship between the independent variable (A) and the mediator variable (B) and a second variable (E) moderates the relationship between the mediator variable (B) and the outcome variable (C).
