“c” represents the total effect of independent variable (X) on the dependent variable (Y), “αβ” represents the effect of X on Y adjusted for the effect of the mediator M, “β” measures the relation between the mediator M and the dependent variable Y adjusted for the independent variable X, and “α” measures the relation between X and M.
