With each revision of the DSM, the criteria for PTSD have changed substantially 2. Following publication of the fourth edition of the DSM (DSM-IV) in 1994 3, PTSD experts criticized the criteria extensively, proposing myriad ways to address the problems they identified 4,5,6,7.

Therefore, this article will refer to these two versions together as DSM-IV/-TR.
