This digest reviews current research on girls' delinquent and violent behavior, the factors contributing to it, and effective programming strategies to prevent it. Girls are more involved in violent crime than they were a decade ago. Their murder rate is up 64%, although status offenses (offenses only because the perpetrator is a minor) continue to comprise most of girls' arrests. The violent crimes committed by girls differ from offenses by boys. Girls are more likely to use knives, more likely to kill someone as a result of a conflict rather than during a crime, and more likely to murder or fight with family members. Current research on adolescent violence and delinquency considers how social class, race, ethnicity, and culture interact to cause young women to behave violently. To serve young women effectively, programs must develop culturally sensitive, gender-specific approaches to intervention. A recent review of existing programs for girls suggests that three common elements combine in program success: (1) comprehensive counseling; (2) educational and occupational support; and (3) support for young women not able to remain with their families.
