Hi,
Do anyone know whether I can introduce a new mediator on a confirmed relationship between IV and Mediator in a new experiment?
In my study 1 and 2, I have established moderated mediation relationship between IV ---M2---DV. Moderator has confirmed between IV and Mediator. Now, I am developing my study 3, I want to introduce a new mediator between IV--M2. Is it methodologically right?
Best,
Yuanyuan
