Hello All,
Please consider 3 variables:
- DV - dependent
- IV - independent
- MV - mediator
Am using PLS-SEM for analysis. And this is my problem
IV --> DV is a negative, insignificant relationship (acceptable according to theory)
But on introducing a mediator:
IV --> MV --> DV, I get the following:
1) IV --> MV: significant negative (expected according to theory)
2) MV --> DV: significant positive (expected according to theory)
3) IV --> DV: significant positive (certainly not expected)
Variance inflation factors have been checked and are not an issue.
I have been reading about suppression, but I am not sure that is the case here.
Would be most grateful for any suggestions.
Thank you,
Navya
