An 8-Hour Livestream Seminar Taught by Amanda Montoya, Ph.D.

Mediation and moderation analysis is ubiquitous in social-behavioral sciences; however, most resources for these analytic approaches only cover between-subject designs – where individuals are randomly assigned to a condition or observed once on all variables of interest.

This mini seminar focuses on how to apply these analyses in simple within-subject designs: 1) within-subject experiments where individuals are observed under multiple conditions, 2) pre-post designs where individuals are observed before and after an event/treatment/training and may also be randomly assigned to conditions. Development of within-subject mediation and moderation has been relatively recent, and this workshop will teach students how to use a new analytic tool for this purpose: the MEMORE macro (freely available for SPSS and SAS).

Taught by the creator of this macro, students will learn to estimate and interpret mediation and moderation analyses for simple within-subjects designs. They will learn to conduct power analysis for these designs, how to properly preregister these analyses, describe causal limitations of these analyses, and how to write up results and create graphics to support analyses. Finally, we will describe extensions of these approaches to more complex within-subject designs (e.g., multilevel and longitudinal models), and where to learn more about these approaches.

By the end of this class, you will be able to:

• Identify and describe designs for which within-subject mediation and moderation can be used.
• Conduct within-subject mediation and moderation analysis using the MEMORE macro.
• Estimate and interpret total, direct, and indirect effects estimated from within-subject designs.
• Estimate and interpret conditional effects and interactions in within-subject designs.
• Describe causal limitations of mediation and moderation analysis in within-subject designs.
• Conduct power analysis for within-subject mediation and moderation analysis to plan sample size for future studies or evaluate adequacy of sample size in existing studies.
• Write and evaluate reports (e.g., preregistrations, manuscripts, grant proposals) describing plans or results of within-subject mediation and moderation analysis.
• Generate graphs and visual diagrams to describe results of within-subject mediation and moderation analysis.
