Preventing it is really very hard. What I think we try to do is recognize it and screen everyone who comes home from combat for PTSD. We have had the best experts we know of develop some screening tools that we have made available and we've mandated the use in every one of our facilities. So everyone gets screened, and if you screen positive then you get a mental health visit right away.
So I think we have become very good at recognizing PTSD and in making sure that when we find somebody with a positive screen we refer them on immediately. We also have what we call our mental health initiative, which began about two years ago, whereby we have required that anyone who comes to us or who calls us with a mental health issue be seen--if it is an urgent situation--immediately. But in all cases, a mental health appointment needs to be made in seven days.
