The term resiliency is used to describe the "human capacity and ability to face, overcome, be strengthened by, and even be transformed by experiences of adversity." Native American culture provides a framework for fostering resiliency. The Lakota Sioux society identifies four core needs that foster resiliency and motivate individuals to reach their potential. These fundamental needs include belonging, mastery, independence, and generosity and are laid out in a model known as the Circle of Courage. Viewing the Circle of Courage through the lens of Urie Bronfenbrenner's Ecological Systems Theory, an approach to human development, offers a framework for understanding teenage resiliency. Bronfenbrenner's theory allows for a close examination of human development through the division of five environmental subsystems: (1) microsystem; (2) mesosystem; (3) exosystem; (4) macrosystem; and (5) chronosystem. This research purposed to examine resiliency factors in Native American teenagers using the structure of Bronfenbrenner's Ecological Systems Theory. The focus was on strengths, not weaknesses, found in at-risk populations. Recommendations are also offered to aid educators in fostering resiliency in Native American adolescents residing on reservations. (Contains 3 tables.)
