I don't know if this is multiple choice, but there are MANY negative effects of domestic violence on families- especially children. I suggest you read articles such as this one: https://www.aafp.org/afp/2002/1201/p2052.html?printable=afp
It brings out many important facts, but here is a sample:
"Children who witness domestic violence are at greater risk for internalized behaviors such as anxiety and depression, and for externalized behaviors such as fighting, bullying, lying, or cheating. They also are more disobedient at home and at school, and are more likely to have social competence problems, such as poor school performance and difficulty in relationships with others. Child witnesses display inappropriate attitudes about violence as a means of resolving conflict and indicate a greater willingness to use violence themselves."
