I grew up in a rather unusual environment where there was a high level of structure, a clear 'purpose' to life, and a safe, understandable environment to learn in. I did not really experience adolescence until well into my twenties when I had moved back into a more standard Western-European way of life. In my attempts to deal with that I found a support group of people coming from similar backgrounds, and regardless of their personality they largely had a similar experience. Anecdotally that at least seems to support your theory.
