Using multiple regression analysis on my data, I've discovered a suppression effect.

Now I started analyzing the same data with AMOS (mainly because I am testing mediation in the same model) and am not sure how to construct the model to test for the significance of the suppression.

anybody any clue???

Thousand thanks in advance...

PS. I've read this brilliant article by Cheung & Lau ("Testing mediation and Suppression Effects of Latent Variables") which helped me a lot concerning the mediation testing. They also explain WHAT a suppressor is and how to interpret it. However, the do not state explicitely HOW to test it. (all they say is that the procedure is "similar").

I find it unlogical to use the same kind of model as for mediation (ie independent variable -> suppressor -> dependent variable) because - although the suppressor can be defined as an 'intervining' variable - it is not influenced by the independent variable.
