school based screening for psych/behavioural problems??

If you are in a school based setting, or in your office practice -- Do you
use any formal
screening instruments in your assessments for depression, anxiety, adhd,
eating disorders, somatization, substance abuse?
Which ones have you found most helpful - could you share resources for
ordering?

As a school nurse I'm responsible for two high schools and one elementary -
its a lot of kids! And
I'm wondering if I could do some screening to identify those kids I've got to
assess more carefully and refer for care.

Respond to me via email hidden@email-address or fax at 818 882 6688 though
I'm sure the list as a whole would also be interested.

Thanks,
