We can also compute means and standard deviations for use in … In this post, I step through how to run a CFA in R using the lavaan package, how to interpret your output, and how to write up the results. To review, the model to be fit is the following: For moderation analysis we also included some nice features like floodlight analysis, surface analysis and simple effects analysis.

In this case, a and b reflect the indirect path of the effect of \(\mathrm{X}\) on the outcome through the mediator, while c' is the direct effect of \(\mathrm{X}\) on the outcome after the indirect path has been removed (c would be the effect before positing the indirect effect, and c - c' equals the indirect effect). Mediation analysis in social psychology: Current practices and new recommendations. The total effect of \(\mathrm{X}\) is the combined indirect and direct effects. So its is definitely worth to have a look at. 5 Moderated mediation analyses using “lavaan” package. I want to take my career to the next level and get into a full-time data analysis type role and I am wondering whether I should do a boot-camp like Coursera or go back to school for a stem degree. This seminar will show you how to perform a confirmatory factor analysis using lavaan in the R statistical programming language. Journal of Statistical Software. tl;dr. You can now do mediation and moderation analyses in jamovi and R with medmod; Use medmod for an easy transition to lavaan; Introducing medmod. Con rmatory factor analysis Latent variable paths Multi-trait multi-method analysis Latent (growth) curve models Moderation and mediation models 17/19. Best regards,

For the analyst familiar with linear regression fitting structural equation models can at first feel strange. It specifies how a set of observed variables are related to some underlying latent factor or factors. This seminar will show you how to perform a confirmatory factor analysis using lavaan in the R statistical programming language. I was able to use the lavaan package to calculate some initial indirect effects based of the syntax available in this post: Multiple mediation analysis in R. However, I do not know how to access an output of values for conditional indirect effects once I add the interaction term into the equation. Structural equation modeling with R (lavaan package) [Google Scholar]
The model, which consists of two latent variables and eight manifest variables, is described here.

Most of the time it means you know how to run standard mediation or moderation models and are now ready to delve deeper into the world of process models. 2011; 5 (6):359–371. mediation analysis in R lavaan, interpretation Showing 1-2 of 2 messages. Social and Personality Psychology Compass. Rosseel Y. lavaan: An R Package for Structural Equation Modeling. In the R environment, fitting structural equation models involves learning new modeling syntax, new plotting syntax, and often a new data input method.

This tutorial shows how to estimate a confirmatory factor analysis (CFA) model using the R lavaan package. The PROCESS macro has been a very popular add-on for SPSS that allows you to do a wide variety of path model analyses, of which mediation and moderation analysis are probably the most well-known.


Thanks to the important comment of John Madden I'll differentiate between moderation (the thing you are probably looking for) and mediation.. Moderation (interaction of variable values) The quick answer to your question is: To my knowledge there is no lavaan-integrated possibility to do an interaction of two latent variables, but here is my go at a workaround: The model, which consists of two latent variables and eight manifest variables, is described here. In “lavaan” we specify all regressions and relationships between our variables in one object. The PROCESS macro has been a very popular add-on for SPSS that allows you to do a wide variety of path model analyses, of which mediation and moderation analysis are probably the most well-known. CFA using the lavaan package in R. Caleb Scheidel. To review, the model to be fit is the following: Let us first generate a dataset with interaction. 2012; 48 (2):1–36. Posted on Jul 8, 2019 R CFA lavaan. 10 comments. This report contains R code for estimating latent variable interaction with the product indicator approach, using the R package lavaan. tl;dr. You can now do mediation and moderation analyses in jamovi and R with medmod; Use medmod for an easy transition to lavaan; Introducing medmod.

You can use lavaan to estimate a large variety of multivariate statistical models, including path analysis, confirmatory factor analysis, structural equation modeling and growth curve models. [Google Scholar] Rucker DD, Preacher KJ, Tormala ZL, Petty RE.
