Increasingly, researchers have linked greater self-determination capacities to improved postsecondary outcomes for youth with disabilities. Although leadership is one component of self-determination, little is known about how youth and young adults with disabilities define, develop, and demonstrate leadership. In this qualitative interview study, the authors examined the perspectives on youth leadership development of 34 young adults with disabilities. Participants identified key attitudes and skills possessed by leaders and addressed the influence these qualities have on others. They also communicated their own experiences of developing their capacities as leaders, emphasizing the importance of early involvement in school and community activities and their relationships with family members, teachers, mentors, and friends. The authors offer recommendations for fostering youth leadership during the transition period. (Contains 2 tables.)
