Hello everyone! I want to conduct a mediation analysis and basically use half of my data. The way I want to halve my data relates to one condition (Dutch/EE accent group) so it's a 0/1 binary condition. The problem is that when I conduct mediation analysis through ProcessMacro, I do not see an option to analyse only the group that I am interested in separately and not all together. So if I want to explore just the Dutch accent group for example, the output I am getting is for the Accent variable as a whole, and not for the half that I need. Does anyone have any idea how I can tackle this? 

P.S the condition variable Accent is an independent variable, not the mediator itself (if that's of any help). 

Thank you everyone in advance! 

Why not just run a SELECT IF or FILTER command first?

It works but I get an ERROR: One of your model variables exhibits no variation (it is a constant); 

It is a constant because it selects one of two conditions.  Is there a way to go around that?
