Ask the Library: Reference

I would recommend searching in a couple of places:

1. You'll need to start at the Library's home page and click on Databases
2. Look for Credo Reference
3. Do a search using Posttraumatic Stress Disorder

This should give you some results on what PTSD is along with symptoms.

If you need a  more in-depth peer-reviewed article for your research you should go into PsycARTICLES in the Psychology databases and search on Posttraumatic Stress Disorder AND symptoms.
