I have looked into it a little. What we know is that yes, violence is present in couple relationships and intimate relationships in adolescence, so it is important to work at earlier points. We have to work on prevention, even with the youngest ones.
However, what we know about violence in romantic relationships among young people is that often, that violence does not correspond to the traditional model of spousal violence where we see a man or a boy who is physically violent against a female partner who is relatively passive and will have physical marks. The violence takes different forms. There may be younger victims who react more and resist. Again, that may adversely affect the way some people understand these situations, because the aggressor and the victim will not necessarily correspond to the picture they have of spousal violence.
We have to ensure better understanding and offer training so that people understand the dynamics of spousal violence when it is expressed more by control and deprivation of freedom than by assault or physical violence. That could provide better tools for the actors who are called on to intervene with this population.
