I read the thread on that topic, and I'll look again but even there it does not say it has to be a direct threat to existence...it mentions other trauma. But in my case it was anyways, even so I don't think the new criteria disqualifies people who got PTSD through long term but not exactly deadly abuse. Also I think its a slippery slope trying to disqualify things like bullying but that is not the impression I got from the APA thread.
This is the APA's DSM V Criteria for PTSD;
A. Exposure to actual or threatened a) death, b) serious injury, or c) sexual violation, in one or more of the following ways:
1. directly experiencing the traumatic event(s)
2. witnessing, in person, the traumatic event(s) as they occurred to others
3. learning that the traumatic event(s) occurred to a close family member or close friend; cases of actual or threatened death must have been violent or accidental
4. experiencing repeated or extreme exposure to aversive details of the traumatic event(s) (e.g., first responders collecting human remains; police officers repeatedly exposed to details of child abuse); this does not apply to exposure through electronic media, television, movies, or pictures, unless this exposure is work-related.
As you can see there is no way workplace bullying now falls into this category. Unless there were direct threat to the person as in serious injury. It would no longer be called bullying if that were the case.
