Any approach to get the mediator-specific natural effects when multiple mediators exist? #41

I am making a multiple mediation analysis( include 4 independent medaitors) and want to obatain path-specific effect of each of medaitors. But there is no available method in the CMAverse .

Hi, if the mediators are independent given the exposure and confounders, the path-specific effect of each mediator can be obtained by fitting a single-mediator model for each mediator separately.

But which modeling approach I can choose ? If I use the weighting-based approach when dealing with parallel multiple mediators by fitting a single-mediator model for each mediator separately, will there be some problems( e.g. outcome model misspecification)？
