Teen dating abuse may be physical, sexual, financial, verbal or emotional in nature.
While abuse often occurs as a pattern of controlling behavior, a single episode of abuse is cause for concern.
And early exposure to abusive or violent relationships increases the likelihood of those types of relationships being repeated later in life.
It's critical that teens have access to information about healthy dating behaviors and warning signs that their relationship might be abusive.
In this study, the correlation between early maturity and dating violence was stronger when girls said they had a lot of boys in their circle of friends.
may be more vulnerable to abuse from a boyfriend, new research suggests.
These girls were more likely to say a boyfriend had verbally or physically abused them: 32 percent did, versus 28 percent of their peers who went through puberty "on time."It's a small difference, said senior researcher Sara Jaffee, a professor of psychology at the University of Pennsylvania in Philadelphia.
Clearly, Jaffee pointed out, not all girls who mature early experience -- and girls who mature later are not immune from it.
