Mediation Indirect Effect Variance Formulas

Mediation Indirect Effect Variance Formula

Below you will find descriptions and details for the formula that is used to compute the variance for the indirect effect in a mediation model.

Indirect mediation effect variance:

Variable definitions:
A = regression coefficient for the relationship between the independent variable and the mediator
B = regression coefficient for the relationship between the mediator and the dependent variable
SE_A = standard error of the relationship between the independent variable and the mediator
SE_B = standard error of the relationship between the mediator variable and the dependent variable
