Physical and psychological teen dating violence is a major problem due to its serious consequences. A first objective of this study was to analyze the prevalence of physical and psychological teen dating violence, both occasional and frequent. A second objective was to analyze its relationship with self-concept and peer violence. 672 adolescents (48.4% boys; 51.6% girls) from 12 to 19 years old (M= 14.45, SD= 1.62) completed the Conflict in Adolescent Dating Relationships Inventory, the Self-Concept AF-5, and the Scale of Aggressive Behavior. Results indicate that adolescent boys and girls who are frequently involved in dating violence, physical and/or psychological, also show more peer violence and lower family self-concept. Boys show lower social and emotional self-concept, while girls show lower academic self-concept. These variables may be relevant to the prevention of teen dating violence.
