Categorical Data Analysis: log linear analysis

Hey guys,

I'm very new to statistics so I have a question:

Consider gender (G), neuroticism (N), openness (O), major depression (MDD),
and generalized anxiety disorder (GAD). I am using MDD and GAD as response variables and the others as explanatory. I have to perform a loglinear analysis.

What is the most simple model to fit in this case, taking into account that there are two response and three explanatory variables? Then I have to fit the model.

Can anyone point me in the right direction?
(I'm using SPSS btw)
