Study examined adolescents' participation in sports, school, and community extracurricular activities to assess the influence of different involvement roles and adult support on leadership skills. The study found that males and females who perceived their adult support more positively had more positive perceptions of their leadership skills. Findings suggest adolescents' perceptions towards their leadership skills are influenced by extracurricular activity involvement roles and the support of their parents and other adults. The findings contribute to future school and community based prevention and intervention programs, suggesting the importance of adolescent leadership involvement at all grade levels and the influence of adult support on adolescents' perception toward their leadership skills. Educators should consider facilitating youth leadership through extracurricular activities involving younger high school students. This affords the opportunity for youth to develop critical skills early and put into practice what they learned. We strongly encourage adult involvement in extracurricular activities.
