I want to examine the relationship between A and B, and C is a moderator. I found that the variable "C" which is the moderator has interesting antecedents that I would like to examine. Actually, this can be one of my contributions!. However, I have never seen a model that examines the relationship between two variables and at the same time examining the antecedents of a moderator! The model I draw even looks a bit weird (see the attachment). So, my question is: is it appropriate to examine the antecedents of a moderator? Can you show me examples, please!
