This may be a stupid question but I am getting myself confused. I have run the analysis for my mediation model using Hayes PROCESS and in the process of writing the findings up. However, when writing the equation for the overall model showing variance in outcome variable explained by predictor and mediation variables, I am confused as to which model summary section of the output to read. Do I take the R squared and F values from the output involving the predictor and meditation variables, or the values from the total effect section which only appears to include to predictor variable?
