Components of an effective treatment program for violent adolescents, and the complex problems posed by youth gangs, are discussed. It is proposed that traditionally taught martial arts can provide a useful alternative for such dysfunctional adolescents. The literature on the use of martial arts in the treatment of violence is reviewed, and the program philosophy is described. The program utilizes a commitment to respect and self-control, with an emphasis on leadership and community service using the traditional model of a gentle warrior. Oversight is provided by trained instructors, whose psychological and philosophical approach stresses nonviolence. The program also assists youths in coping with the complexities of an often dysfunctional family environment. Clinical examples detail the application of such a program in specialized martial arts schools, residential treatment, and public school classes.
