ok, I was planning to compare a few models with different variables.I did adjusted Wald tests to  test the coefficients and they are all significant. 
therefore I guess there is no point comparing these models.

Basically, there isn't anything.  Standard GOF measures don't apply to
survey estimates.  You can try a truth (contingency) table, categorizing the
predicted probabilities and comparing them to the actual outcomes.

Sorry for the stupid question but I would like to know how do you assess
the goodness of fit of a svy olog when the log likelihood estimates are
not displayed.
I am really stuck..and I hope somebody will answer!
