Statistical mediation and moderation analyses are among the most widely used data analysis techniques in social science, health and business research. Mediation analysis is used to test hypotheses about 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.” Increasingly, moderation and mediation are being integrated analytically in the form of what has become known as “conditional process analysis,” used when the goal is to understand the contingencies or conditions under which mechanisms operate. An understanding of mediation and moderation analysis is in the job description of almost any empirical scholar. In these courses, you will learn about the underlying principles and the practical applications of these methods using ordinary least squares (OLS) regression analysis and the PROCESS macro for SPSS, SAS and R, invented by the course instructor and widely used in the behavioral sciences. These courses are a companion to the instructor’s book Introduction to Mediation, Moderation, and Conditional Process Analysis, published by The Guilford Press.
We are offering three versions of this course, an introductory level treatment (HSK 847), a more advanced "second course" (HSK 848) that expands on HSK 847 by covering more complex problems to give you greater breadth of knowledge, and a "complete course" (HSK 849) that covers all of the material in HSK 847 and HSK 848 plus a few additional topics and at a reduced price. All courses are delivered online and on-demand, meaning you can begin the course as soon as you pay the registration and are enrolled in the course through our online course management system. The content is delivered by pre-recorded video, and you can progress through the modules and activities in the course at your own pace until the end of your access period. There are no set times in which you must participate or be online during your access period. You can interact with the instructor over email, in real time during occasional office hours on Zoom, or (in HSK 849 only) through a discussion forum on the course portal. The access period begins when you are enrolled in the course and ends after 45 days (HSK 847/848) or 100 days (HSK 849).

All courses are delivered online in an asynchronous format through pre-recorded video using our online course management system at http://ccram.digitalchalk.com. Learners can begin the course when registration is completed, and access to the content is provided for 45 days (HSK 847, HSK 848) or 100 days (HSK 849) after registration. There is no limit to the number of times a video can be viewed, and controls for pausing, forwarding, and rewinding are provided on the user interface. Each course also contains a number of downloadable activities and self-assessments, with corresponding videos describing the answers to each activity and assessment task.
All data files, statistical code, activities, and PDFs of content of the videos can be downloaded and saved to the learner's storage medium for viewing even after the end of the access period. Videos cannot be downloaded or viewed offline.
In all courses, learners can interact with the instructor through email as well as in real time during occasional (about once per week) virtual office hours using Zoom. In HSK 849, an online discussion forum is also provided for learners and the instructor to interact during the learner's access period.
All courses are taught in English. There are no foreign language subtitles or closed captioning available on the videos, and all course materials are provided in English.
Computer applications will focus on the use of ordinary least squares regression and the PROCESS macro for SPSS, SAS and R, developed by the instructor, that makes the analyses described in this class much easier than they otherwise would be. This is a hands-on course, so maximum benefit results when learners can follow along with analyses using a laptop or desktop computer with a recent version of SPSS Statistics (version 27 or later), SAS (release 9.3 or later, with PROC IML installed) or R (version 3.6 or later; base module only. No packages are used in this course). Learners can choose which statistical package they prefer to use. STATA users can benefit from the course content, but PROCESS makes these analyses much easier and is not available for STATA. You can keep what you download, but videos are not downloadable.
The course content can be viewed from any technology capable of accessing web pages and viewing video files, including most tablets, phones, desktop, and laptop computers. An internet connection is required.
These courses will be helpful for researchers in any field – including psychology, sociology, education, business, human development, social work, public health, communication and others that rely on social science methodology – who want to learn how to apply the methods of moderation and mediation analysis using widely-used software such as SPSS, SAS and R.
Learners are recommended to have familiarity with the practice of multiple regression analysis and elementary statistical inference. No knowledge of matrix algebra is required or assumed, nor is matrix algebra used in the delivery of course content. Learners should also have some experience with the use of SPSS, SAS or R, including opening and executing data files and programs.
Upon completion, you will be able to:
- statistically partition one variable’s effect on another into its primary pathways of influence, direct and indirect
- understand modern approaches to inference about indirect effects in mediation models
- test competing theories of mechanisms statistically through the comparison of indirect effects in models with multiple mediators
- understand how to build flexibility into a regression model that allows a variable’s effect to be a function of another variable in a model
- visualize and probe interactions in regression models (e.g. using the simple slopes/spotlight analysis and Johnson-Neyman/floodlight analysis approaches)
- integrate models involving moderation and mediation into a conditional process model
- estimate the contingencies of mechanisms through the computation and inference about conditional indirect effects
- determine whether a mechanism is dependent on a moderator variable
- apply the methods discussed in this course using the PROCESS procedure for SPSS, SAS and R
- talk and write in an informed way about the mechanisms and contingencies of causal effects
A certificate of completion from the Canadian Centre for Research Analysis and Methods is provided at the end of the course.
In these courses, we focus primarily on research designs that are experimental, cross-sectional, or 2-wave longitudinal in nature, with continuous outcomes. We do not cover complex models involving dichotomous outcomes, latent variables, nested data (i.e., multilevel models) or the use of structural equation modeling. We also do not address the "counterfactual" or "potential outcomes" approaches to mediation analysis or discuss directed acyclic graphs (DAGs). Some of these topics that are not covered can be quite a bit more complex and require familiarity and comfort with the fundamentals covered in these courses. Thus, these courses serve as a good starting point for your journey of continuous learning..

When is the deadline for enrolling?
There is no deadline to enroll. You should enroll when you are ready to begin learning. We will be here when you are ready.
How long does the course last?
Once you have enrolled in a course, you will get either 45 days (for HSK 847 and 848) or 100 days (for HSK 849) to complete the course. Otherwise, you can progress through the content at your own pace. Some people complete the course in as little as a couple of weeks, other people take most of the time they are given. The course is as short or as long as you want it to be, within the 45 or 100 day constraints mentioned above.
What if I can't be online at certain times. Will I miss things?
The lectures are all prerecorded and are available for you to view when you are ready. These are not live stream courses that require you to be online at certain times. You can log in to your CCRAM Digital Chalk account and progress through the content when you have time. There are occasional office hours with the instructor that are conducted live through Zoom. These are scheduled about once a week at various times that change from week to week. But attendance at these is optional. Some people regularly attend office hours. Others attend only one or two. Still others never attend at all. It is up to you.
What if I run out of time before finishing the course?
If something comes up and you find you cannot complete the course in the 45 or 100 day window, you can purchase an extension of your time. Instructions for how to do this are available on the main course portal page once you have enrolled. You can request an extension right before your time is up using the link on the course portal, or up to one week after your access has ended. After you access has ended, you should email ccram@ucalgary.ca for instructions, since you wont have access to the course at that point..
Are the videos downloadable? Can I view them when not online, such as on an airplane?
No, the videos can only be viewed when online and cannot be downloaded. But the data files and code and the PowerPoint slides that are used in the videos can be downloaded and are available for you to keep on your own storage medium for as long as you want.
Do I need to have a computer or laptop to watch the videos?
The videos can be viewed on most electronic devices that can display mp4 files, including phones, tablets, laptop and desktop computers, etc.
Will I get a certificate of completion once I finish the course?
If you want one, a certificate documenting that you took the course can be provided to you by the CCRAM staff if you ask by emailing ccram@ucalgary.ca once you have completed the course.
There are many people in my department that would like to take this class. Can we take it at the same time? Will you give group discounts?
Contact ccram@ucalgary.ca to arrange a group discount if you group is 4 or more people and everyone wants to start the course at the same time. For 15 or more people, we recommend contacting ccram@ucalgary.ca and ask about about hosting a CCRAM session. This would allow you to decide when the course starts and stops, and private office hours for your group can be set up on a schedule that is convenient to your group.
