Mediation Step by Step
With Bootstrapping
Here is the model we’ll be testing
Step 1: Create TableHypothesis Direct Beta w/o

Partial Med MU-Burn-Satw
Partial Med Part-Burn-Satw
Step 2: Direct Effects Significant?
Estimate S.E. C.R. Psatw <--- part .130 .050 2.594 .009satw <--- mu -.525 .040 -13.102 ***
Regression Weights: (Group number 1 - Default model)
Step 3: Update Table

Step 4: Set up Bootstrap
Step 5: Run with Mediator
If it throws you an error when you run it with bootstrapping, just run it again, and again, and again, until it runs without an error. If this still doesn’t work,
then close and reopen AMOS and try again.

No Mediation• If Indirect is not significant• Also if direct effect of IV on Med is insignificant or if direct effect
from Med to Y is insignificantIndirect Effects• Both direct effects are not significant, but Indirect effect is significantFull Mediation• Given the direct effects were significant prior to adding the mediator• If Indirect is significant and Direct (with med) is not significantPartial Mediation• If Direct (with med) & Indirect are significant
