The New York City Alliance Against Sexual Assault, in collaboration with Columbia University Mailman School of Public Health's Center for Youth Violence Prevention, announced the results of a three-year, comprehensive research project on sexual and dating violence among New York City high school students, and the health impact of that violence on those victimized by it. A copy of the full study, "Partners and Peers: Sexual and Dating Violence Among NYC Youth," will be released in July. The New York City Department of Education granted researchers permission to enroll New York City high school students anonymously with their parents' consent and their own permission given the agreement of school principals and district superintendents. Students from four schools, reflecting a range of those in New York's cultural groups, were asked to participate. Over 1,300 high school students ranging in age from 13-21 were included in these analyses. The majority of participants were 15 or 16 years old.
