List and explain some of the risk factors associated with the development of PTSD following a traumatic event.

What qualifies as traumatic? Do all people experience trauma in the same manner? Can PTSD only be experienced by combat veterans? Explain all answers thoroughly and with documentation. Be sure to cite and reference your sources using APA writing style.

I will also need APA in text citing.
