You can either use structural equation modeling or Hayes’ Process macro. Both are equally good.

Saeid Nosrati

Thank you so much for your kindly response.

Guy Curtis

I agree with looking at Hayes's Process macro. This is a good starting point too: http://davidakenny.net/cm/mediate.htm

Dear Dr Guy Curtis

Thanks a lot for your kindly response.
