Add a course of mine to your academic schedule.
- "Mediation Analysis" and "Interactions in Regression Analysis" are offered in person in Calgary, Alberta, Canada, July 15-16 and 18-19, 2025, through the Canadian Centre for Research Analysis and Methods during CCRAM's Rocky Mountain Methodology Academy. Both emphasize the use of the PROCESS macro for SPSS, SAS, and R. A day trip to Banff is included with your registration. Eight other courses in behavioural science statistics and methods are offered during the academy.
- "Mediation, Moderation, and Conditional Process Analysis: The Complete Course On Demand" is being offered online through the Canadian Centre for Research Analysis and Methods and runs from September 9, 2025 to March 9, 2026. Content is delivered asynchronously, with occasional office hours administered live through Zoom. You can learn at your own pace. There are no set times when you must be online.

My research focuses on linear models, with an emphasis on resampling methods of inference. Specific areas of investigation and writing include statistical approaches to assessing mediation, moderation, and the contingencies of mechanisms. I hold a Ph.D. in Psychology from Cornell University (1996) and a B.A. in Psychology from San Jose State University (1991).
My methodology work is published in such locations as Psychological Methods, Multivariate Behavioral Research, Behavior Research Methods, Psychological Science, the British Journal of Mathematical and Statistical Psychology, Behaviour Research and Therapy, American Behavioral Scientist, and Communication Monographs. In January 2022, The Guilford Press released the 3rd edition of "Introduction to Mediation, Moderation, and Conditional Process Analysis: A Regression-based Approach". Guilford also published my third book, "Regression Analysis and Linear Models," coauthored with Richard Darlington. In 2005, Lawrence Erlbaum (now Routledge) released my first book, "Statistical Methods for Communication Science."
If you would like to come work with me as a Ph.D. student, you would do so by applying to the Ph.D. program in Management at the Haskayne School of Business at the University of Calgary. Contact me at andrew.hayes@ucalgary.ca to talk about the possibilities as a Ph.D. student as well as other collaboration opportunities.
