Perhaps it might also be helpful to examine the
psychometric characteristics of your dependent
variable measures?
What tests are/were used to measure depression and
anxiety? Have confirmatory factor analyses and/or
Rasch analyses been performed on your scales to assess
dimensionality and content?
Constructs like "depreession" and "anxiety" can be
complex---are they best measured as binary constructs?
