Research
As an academic, I am interested in dyadic data analysis, mediation and moderation analysis, longitudinal data analysis, intervention research, and personal relationships. I have written about the distinction between partial and full mediation and the importance of effect sizes as well as the analysis of dyadic data using Multilevel Modeling (MLM) and Structural Equation Modeling (SEM). A complete list of my publications is available on Google Scholar. R code accompanying my methodological papers is available for download on my GitHub account. I offer workshops on quantitative data analysis techniques, particularly the analysis of dyadic data.
Models and methods introduced
– The Common Fate Growth Model for analyzing change at the dyadic level (Ledermann & Macho, 2014).
– The Multilevel Common Fate Model for analyzing effects at the individual and dyadic level, the Two-Factor Common Fate Model with method factors, and dyadic hybrid models (Ledermann & Kenny, 2012).
– The mediation and moderation Actor-Partner Interdependence Model (Garcia, Kenny, & Ledermann, 2015; Ledermann & Bodenmann, 2006; Ledermann, Macho, & Kenny, 2011).
– The Multimember Multigroup Actor-Partner Interdependence Model for analyzing group effects in dyads and triads (Ledermann, Rudaz, & Grob, 2017).
– Parameter k for testing patterns in the Actor-Partner Interdependence Model (Kenny & Ledermann, 2010).
– The Phantom Model Method for testing and comparing specific effects in complex models (Macho & Ledermann, 2011).
Concepts and scales introduced
– The Caring for Bliss Scale (CBS; Rudaz, Ledermann, Ross, & Fincham, 2020).
– The Genuine Happiness Scale (GHS; Rudaz, Ledermann, & Fincham, 2022).
– The Relational Cultural Intelligence (RCI) scale (Su & Ledermann, 2025).
