There is some empirical evidence to suggest that the women who saw their fathers physically abusing their mothers in their childhood are more likely to justify spousal violence as adults compared with the women who did not have the similar experience in their childhood. One expects that there is a psychological/social/economic mechanism which links the childhood experience of domestic violence of the girls and their attitudes towards domestic violence when these girls grow up to take up spousal role. I would be obliged if someone could answer this question.
