Ugh...good question..
I don't imagine staff members are given much creative leeway in how to help their "patients" grow. I doubt hanging out is part of their job description. The system that determines what Americans need to be administered/what they should do when they are ill is so well established, it's hard to think about how it might change.
Those of us who "end" UP there don't exactly have control over what we are exposed to or how we are cleansed. We should be terrified for the people who have developed schitzophrenia. A close friend of mine, a psychologist, doesn't even believe such people can recover themselves using any mechanism on or above Earth, at present. So, a lot of methods aren't even tried out...
If themes in any of the movies that portray the social interactions of these stimuli-restricted people who need psychoLOGICAL help are accurate, we all need to consider what positively influences our own mental health, discover how these factors are lacking in "psych wards," and challenge current methods of intervening on behavior/thought patterns.
