Girls were more likely to say they had physically abused their partners; boys were "much more likely" to say they had sexually abused someone, the association says.
But it did not provide specific numbers on those differences.
The results suggest there is a "violence trajectory" and "if it's not addressed, it will escalate."While programs at school and elsewhere in communities may help, families can play a central role.
In his own survey of 1,525 Latino youths ages 12 to 18, Cuevas says he found that boys with the strong family support "typical in traditional Latino culture" were less likely to psychologically abuse dates.
When you look at serious sexual and severe physical assault, we tend to see a bit more from the boys than the girls."Dorothy Espelage, a researcher at the University of Illinois-Urbana-Champaign, says, "Without measures of fear, severity and injury, we need to be cautious" about interpreting the new nationwide survey results.
Espelage worked on the survey with Ybarra and on another study to be presented today which shows links between middle school bullying and teen dating violence.
The survey also found that 29% of girls and 24% of guys said they had been both victims and abusers, in the same or different relationships.
Lead author Michele Ybarra, a researcher with the Center for Innovative Public Health Research in San Clemente, Calif., said in an e-mail that she could not discuss the study because it is under review for publication in a scientific journal.
The dating line, which offers 24-hour help by online chat (at loveisrespect.org), text (text "loveis" to 22522) or phone (1-866-331-9474), is aimed at young people of both genders.
But abused girls may be more willing to seek help, Jones says: "There's a lot of stigma about boys and men reaching out when they are victims."The new survey results are in the line with some other findings, says Carlos Cuevas, a researcher from Northeastern University-Boston, who is presenting new data on dating violence among Latino youth at the conference.
Teens, like adults, sometimes have trouble recognizing that they are in an abusive relationship, experts say.
