Distorted Obstruct Soul: Culture and Mentality

One question I had was how culture correlates to psychological health. 

If one person born of one culture, was raised by rules of a second culture, and then had interests for a third culture, would those cultures contradict in terms of psychological health?

I may have a slight clue of the answer but still not sure if it's true. It came up around Health 101, yet cannot convey til now. Think about that very question for a while.
