Mediation, Moderation, and Conditional Process Analysis with R

Author

Dr. Nicola Righetti, PhD

Aims, contents and method of the course

This data analysis seminar focuses on linear regression analysis to explore questions about mediated and moderated effects.

Computer applications will focus on R statistical language, the Rstudio environment (https://www.rstudio.com) and the PROCESS software by Andrew F. Hayes (http://processmacro.org).

Learning outcomes

By the conclusion of this course, students should be proficient in:

  • Executing and comprehending the outcomes of linear regression, moderation, mediation, and conditional process models.

  • Statistically testing competing theories of mechanisms through the evaluation of indirect effects in models that encompass multiple mediators.

  • Representing and investigating interactions in regression models to accurately interpret interaction effects.

  • Calculating and inferring about conditional indirect effects to estimate the contingencies of mechanisms.

  • Utilizing the R language and PROCESS to conduct, depict, and comprehend linear regression, moderation, mediation, and conditional process models.
