We have to interact and learn from our environments, especially growing up. We are sort of "forced" to experience them. Of course, as we get older we have some control over that, but there is an element that is always "out of our hands." I definitely believe that the general environment may "prime" us or steer us away from developing mental disorders such as PTSD. Certainly not irrelevant in my book. It may be an insufficient contributor, but this heavily depends on each specific circumstance. Hopefully this gets at your question!
