Has a poll been conducted to see there is a higher incidence or prevalence of depression among people who were in Straight or the Seed as compared to people of the same age who were never in those programs? It might be interesting to break it down into subsets of years, since there were times when the program was more violent than others. I think it would probably be interesting to divide the groups by sex, too, since depression is more common among women. Maybe you'd see other psychological issues in men.
If we had a good mailing list, with a couple hundred names at least, we could send it out.
