This brief explores interpersonal violence between adolescents involved in a dating relationship. It begins by defining interpersonal violence before discussing a study that examined the prevalence and patterns of personal dating violence (PDV) among adolescents. The study analyzed data from the Centers for Disease Control and Prevention’s Youth Risk Behavior Survey (YRBS), a self-reported, written instrument that is administered every two years across the US to 9th through 12th grade students in public and private schools. Results are reported related to the prevalence of PDV among teens, the prevalence by gender, and the prevalence of PDV in communities of color. Additional information is shared on the other types of violence that girls who have been exposed to PDV have witnessed, the prevalence of their sexual victimization, their engagement in high-risk sexual behavior, and their rates of depression and suicide ideation. Findings indicate approximately 1 of 3 adolescent girls falls victim to interpersonal violence and that that girls exposed to interpersonal violence show greater exposure to other forms of violence, greater propensity for unsafe sexual activity, and a higher incidence of substance abuse and suicide ideation than their male counterparts or non-exposed females. Recommendations for programming are made. 22 references.
