The output of a mediation analysis is as follow STANDARDIZED MODEL RESULTS STDYX Standardization TwoTailed Estimate S.E. Est./S.E. PValue Y ON GROUP 0.047 0.239 0.195 0.845 X1 0.315 0.152 2.063 0.039 where GROUP is dichotomous (control and treatment), X1 and Y are continuous. How would you interpret the estimate 0.315 for control group? Thank you for your help. Y 


I'm not sure what your question is. If y is continuous, .315 is a standardized linear regression coefficient.

I am sorry for the unclear question. Group has two values 1: treatment, 0: control. Group is not significant. I believe 0.315 is the change in Y (in standard deviation units) when X1 increases by 1 std deviation unit, controlling for group. Does this mean it is the effect of X1 on Y for both treatment and Control? Thank you, Y 


That sounds correct.
