SOBEL TEST Mediation

No signification for small simple size

Test 5

- Install directly to computer

Page 45: Seminar SPSS di UM

To get numbers

1. Run a regression analysis with the IV predicting the mediator. This will give a and sa.2. Run a regression analysis with the IV and mediator predicting the DV. This will give b and sb.

Note that sa and sb should never be negative.

To conduct the Sobel test

Details can be found in Baron and Kenny (1986), Sobel (1982), Goodman (1960), and MacKinnon, Warsi, and Dwyer (1995). Insert the a, b, sa, and sb into the cells below and this program will calculate the critical ratio as a test of whether the indirect effect of the IV on the DV via the mediator is significantly different from zero.

Input: Test statistic: Std. Error: p-value:

a Sobel test:

b Aroian test:

sa Goodman test:

sb

Alternatively, you can insert ta and tb into the cells below, where ta and tb are the t-test statistics for the difference between the a and b coefficients and zero. Results should be identical to the first test,

except for error due to rounding.
