second order IDV and second order Moderator

[asrivastava]

i have a model in which : (having all reflexive constructs)
firstly ,
Im testing for mediation between IDV and DV where IDV is second order.

secondly, From the review of literature i found one second order variable which might act as a moderator influencing the relationship between IDV and DV. I want to test it too.

Further, My EFA shows moderator being a first order , but literature says its being second order, i need some suggestions on how should i model it....?

For testing structural relationships : Need suggestion on how to include this moderator along with the previous mediator analysis.

Should i run both models (moderator and mediator models ) separately, or

Do i need to test , at the end (after running them separately) , where all the mediator and moderator variables , simultaneously are included in the model.

Is there any paper , which i can follow, i need such related readings for journal submission.

thank you
