Mediation analysis, multiple mediators
I am doing a mediation analysis with JASP, first in a simple model with one mediator. The results show a partial mediation with significant direct and indirect effects. The mediator has however three facets/subscales, and I want to find out which facet(s) contribute the most to the significant indirect effect. Do I conduct one mediation analysis with all three facets as mediators or do I coduct three separate mediation analyses?
If I conduct one analysis with three mediators, do I have to obey anything, concerning the covariances of the facets? I am still confused about how exactly the analysis via JASP works, so I would appreciate any help!!
