My colleague Dr. Jeff Morley, who's a psychologist, says it best, that there is no test available to predict who will be susceptible to post-traumatic stress. Unless you want to hire somebody who will be a psychopath or a sociopath, no such test exists. When we look at the causation of PTSD, it's exposure to a traumatic event or a series of traumatic events, and we really can't identify which event might be that trigger.
