Testing and interpreting Moderation and Mediation with SPSS Summer School
Aims
The main objectives of this course are:
- To understand and learn methods of testing and probing different types of interaction effects (moderation) using SPSS.
- To understand and learn methods of testing different types of indirect effects (mediation) using the PROCESS macro.
- To learn about how to combine mediation and moderation using the PROCESS macro.
Information
Mediation and moderation are crucial ways of expanding and testing theory. Moderators are variables that affect the strength and/or direction of relationships between other variables, while mediators are intermediary mechanisms that explain the relationships between other variables. This course will cover how moderation and mediation can be tested, both separately and together, using SPSS.
The morning of day 1 will cover testing and probing two-way interaction effects (simple moderation) and three-way interaction effects (two moderators). Students will be shown how to perform these tests and how to reach conclusions, including a thorough discussion of how results should (and should not) be interpreted.
The afternoon of day 1 will cover testing mediation using the PROCESS macro, and will include discussion of effect sizes, causality, and reporting results. It will also introduce moderated mediation, and some of the simpler models demonstrated.
The morning of day 2 will introduce more complex moderation models, including curvilinear relationships, non-Normal outcomes, and non-linear moderators. It will also include discussion and examples of testing moderation under other methods, including multilevel analysis and structural equation modelling.
The afternoon of day 2 will expand the coverage of moderated mediation to more complex models available with the PROCESS macro, and examples given of how these can be applied in other software. The course will finish with an in-class exercise.
Assessment
Before the course you will receive a pair of papers to read and a set of exercises that have to be completed before the course starts.
At the end of the course there will be a final exercise to be completed during class.
