Let me take those in reverse order.
Absolutely, adversity in childhood, including all forms of violence, losing a parent, or having a parent who has a major mental health problem or a substance use problem or who's incarcerated, is associated with later victimization for women and perpetration for men. It's both for both, but more often it's perpetration for men and victimization for women.
In terms of relapse, yes, we do have information. We don't have as much information as I think we need. We know that when abuse is identified, somewhere between one-third and two-thirds of men go on to not engage in any subsequent abusive behaviour. We know that about one in five engages in subsequent abusive behaviour, often very quickly, often more severely, and often within the first six months.
We know that a range of change does happen. Yes, change does happen, but there are people for whom that change doesn't happen. It's been recognized that their engagement with systems afterwards—that could be any range of systems—predicts less reassault.
