Suppose someone has been using avoidance coping style for most of his or her life. The avoidance tendency is present in a broad range of situations, relatively constant through his or her life, not preceded by a major event or trauma, and not associated with any cognition or emotion.
According to current models, what are the likely causes of the coping style?
How changeable is the coping style through various therapies?
P.S. For the purpose of this question, I only ask about the coping style itself (that is, his or her tendency to avoid as opposed to counterattack or surrender) not the consequences of the coping style (the disorders and pathologies and so on).
