Risk factors for violent behavior in elementary school boys: have you hugged your child today?

Seventeen Hispanic elementary schoolboys with violent behavior problems were compared with 27 matched control students who were not overtly violent at school. Violent boys were significantly more likely to not live with their fathers, to have unmarried parents, to have more siblings, and to have fathers who never show them affection. Parents of violent boys were more likely than those of matched control students to use spanking for discipline and to admit that they rarely express affection for their sons.
