Youth violence in the city of Philadelphia, PA, has reached epidemic proportions. The majority of homicides related to gun violence is most prevalent among African American males aged 19 to 24 years. Therefore, it is essential to implement youth violence prevention programs to a target population several years younger than this age group to decrease teen violence in the city. A violence prevention program for 9th and 10th graders was developed, implemented, and evaluated at a local urban charter school. Presentations were given on gun and gang violence, dating violence, and anger management/conflict resolution as well as role playing, group activities, and a field trip to a trauma program for youth at a local hospital. Posttest scores showed an increase in knowledge and skills in several areas, such as therapeutically resolving violent disputes and methods to prevent different types of dating violence. This program provides a blueprint for an adolescent violence prevention program that school nurses could adopt in their communities. (Contains 1 table.)
