Thank you again, Mashhood.

What I do not understand yet is why we need a package like multimed if we can decompose a model with two causally dependent mediators (infant deprivation --> education level --> economic position --> aging well) into two models (infant deprivation --> education level --> aging well & education level --> economic position --> aging well).

Following your advise, I should include infant deprivation as a confounder in the model education level --> economic position --> aging well. But if deprivation conditions education strongly, I could end not finding any direct nor indirect effect of education on aging well.

Best regards,

Angel Rodriguez-Laso

Hi,

In the model (education level --> economic position --> aging well) you should include all the variables that potentially confound the association between education level and economic position, education level and ageing well, and economic position and ageing well. 

Best wishes,
Mashhood
