Testing Mediating and Moderating Effects Using the Process Macro
50 minutes
Because most social & business research implies the test of some mediating and/or moderating effects (even, some moderatedmediating…), this seminar is designed to present how the Process macro can easily and usefully help researchers test such effects. The emphasis will be first made on the theoretical rationale for such effects but also, importantly, on how to conduct the analyses and report the results.
