The Conservation and Youth Service Corps is comprised of intensive, typically full-time, programs that last between six and twelve months (Jastrab, Blomquist, Masker, & Orr, 1997). Within these programs, participants (usually disadvantaged young people aged 18-25) spend 80% of their time performing community service while simultaneously acquiring work experience and education. Participants work in teams of 8 to 15 members on a variety of service projects in communities nationwide. Corps members follow structured rules designed to foster personal development and responsibility, as well as enhance work skills and decision-making abilities. An important component of Corps programs is the daily presence of crew supervisors; these supervisors serve as adult role models who mentor, advise, discipline, and advocate for participants. Program participants are paid a stipend and may also receive post-program financial aid for education. This program has shown some positive impact on sexual behaviors. Black unmarried women who participated in the program had lower rates of pregnancy at follow-up. Lower pregnancy rates were not observed for Hispanic or non-Hispanic white women.
