looking for methods to examine and graph quadratic effects

[Todd Kashdan]

Hi all:

I am examining several quadratic effects in my
dataset.  This includes simple quadratic main effects
(of appraisals) and trait variables (e.g., depressive
symptoms) as moderators of these curvilinear effects.
I am using SPSS and was wondering what is the best way
to examine and graph curvilinear effects and
interactions between other variables and curvilinear
effects?

any information would be greatly appreciated.

cheers,
Todd
