Taught by Andrew Hayes, Ph.D.

Statistical mediation and moderation analyses are among the most widely used data analysis techniques.  Mediation analysis is used to test various intervening mechanisms by which causal effects operate. Moderation analysis is used to examine and explore questions about the contingencies or conditions of an effect, also called “interaction.” In many ways, an understanding of the fundamentals of mediation and moderation analysis is in the job description of almost any empirical scholar. 

In his recent book, Introduction to Mediation, Moderation, and Conditional Process Analysis: A Regression-Based Approach, Andrew Hayes describes these fundamentals using ordinary least squares regression. He also explains how to use PROCESS, a freely-available and handy tool for SPSS and SAS that brings modern approaches to mediation and moderation analysis within convenient reach. This book has become an instant bestseller, and Professor Hayes’ introductory course offered by Statistical Horizons regularly fills to capacity.

This seminar–a “second course”–picks up where the book and the introductory course leave off.  After a review of basic principles, it covers material that did not make it into the first edition of the book but will likely appear in a future edition. This material is based on many questions Hayes has received from both veteran scholars and researchers in training, including models with multicategorical predictors, dichotomous outcomes, repeated measures designs, and complex models that integrate moderation and mediation components. In this course he also teaches material appearing in recent journal publications, manuscripts in press, and methods still undergoing development. Participants will get the latest release of PROCESS with many new features–before it is released to the public.
