Dear all,

I would like to test a mediation model (the BLUE colour lines and circles of the image attached) and run the statistics via PROCESS macro. I found that Model 6 of PROCESS, the serial mediation model seems to fit it best. However, I would like to add a control variate (GREEN) just to the outcome variable Y. I am aware that there is a 'covariance' box in the PROCESS window, but that covariance applies to the whole model, i.e. every single equation, instead of just the outcome variable Y.

How to add a control variable to Y alone?

And is there a way to just explore the effect between M1 and M2 (the YELLOW arrow) but not the whole path of x-->m1-->m2-->Y?

Thanks!
