I don’t know whether one of the medical people will read this, but I can say that there have been 50 to 200 people wintering at various antarctic stations for over 50 years. It’s a very studied environment. We all undergo physch evals every year. I doubt if there is anything that is not already well documented here.
The bottom line is that there is almost no cabin fever, violence or problems of the sort you say are probable. They did some studies comparing us with similar small towns back home and our rates of problems are way less than normal.
