I said previously that you need to determine whether a 
variable is an intervening or a confounding variable. This means
that you need to formulate a theory of how you believe that all 
your variables are causally related. Based on that theory you 
can determine which variables are confounders and which 
intervening variables. You include the confounders in your model 
and exclude the intervening variables.

Hope this helps,
Maarten
