Mediation and moderation
In this three-day course the core issues of mediation and moderation are explored and practiced.
- Target group
- Elise Dusseldorp (Associate Professor) Peter de Heus (Coordinator)
Deadline registration is Wednesday 16 June 2021.
Within PhD projects, questions often arise about how an effect becomes stronger or
weaker due to some third variable (moderation), or how an effect may be explained by
some intermediate third variable (mediation).
The first day of the course is targeted at the basic concepts of mediation and
moderation (causal steps approach, estimating and testing indirect effects, effect size,
and post hoc probing of moderator effects). On the second day generalisations to
multiple mediators or moderators are discussed. On the third day combinations of
moderation and mediation (moderated mediation) will be discussed, not only as a direct
extension, but also in the new context of within-subjects designs. During both days,
lectures are intermingled with computer practical sessions using SPSS in combination
with SPSS macros PROCESS and MEMORE, and optionally with R.
After this course, you are able to:
- explain the concepts of mediation, moderation, and moderated mediation, and
related issues (e.g., mean centering, causal steps approach);
- choose the appropriate analysis for different research questions involving
mediation and/or moderation;
- perform mediation, moderation, and moderated mediation analysis in SPSS,
PROCESS and MEMORE, and R (optional).
