This study examined the association of victimization in a physically violent dating relationship with risk behaviors, age of risk behavior initiation, and co-occurrence of risk behaviors among students in grades 9 through 12 in the United States. Data were from the 2003 national Youth Risk Behavior Survey (YRBS). Nearly 9% of students reported experiencing dating violence victimization. Dating violence victimization was associated with alcohol use, marijuana use, and having ever had sexual intercourse among female students and having ever had sexual intercourse among male students. Dating violence victimization also was associated with early initiation of alcohol use among female students. The odds of dating violence victimization increased as the number of risk behaviors increased and as the number of lifetime sexual partners increased. These risk behavior patterns should serve as warning signs of elevated risk for dating violence victimization and may be helpful in identifying adolescents who could benefit from targeted, preventive interventions.
