I think they are. That's why I was saying that I'm not keen on the term “OSI”, because I find that it's too broad an umbrella. It's too specific and too broad at the same time.
Because it's made a psychological injury a battle wound, if you have any kind of psychological symptom and you're a soldier, naturally you're going to want to fall under that umbrella because there is some honour to that. The problem with this is that the therapy has to be specific. Even within PTSD, if all you have is PTSD, which is rare and not that common, the degrees of the symptoms are going to be different and there are different strategies for each configuration of symptoms, the same as you would say about a medical condition.
Diagnosis, to me, is the first step to everything. The correct diagnosis is essential.
