Significantly more girls than boys have committed an act of physical violence when dating, according to a longitudinal study presented this week at the American Psychological Association's annual meeting. More from NBC News:
For her study, Dorothy Espelage, professor of educational psychology at the University of Illinois at Urbana-Champaign, and her colleagues conducted a longitudinal study among 625 students starting in grades 5, 6, and 7, and followed them over a period of four years. Researchers interviewed the students at intervals over that time.
The study looked at a spectrum of behaviors, ranging from name calling and expressing anger, spreading rumors, and using controlling behaviors such as keeping track of dating partners, to physical violence such as slapping, hitting and biting, and sexual violence including forced kissing. Taken as a whole, one in three reported being the victim of at least one of the behaviors on that spectrum.
While most of us may not rank name-calling, or bad-mouthing another to their friends as "violence," the researchers say they included the psychological and relationship tactics because they can have a profound impact.
"We see in other research that the psychological stuff has just as much of a negative impact on health outcomes as the physical and sexual" violence, said Carlos Cuevas, associate professor in the School of Criminology and Criminal Justice at Northeastern University, who is also presenting a study on youth dating violence at meeting.
