Our research team recently acquired a grant in 2014 from the Office of Juvenile Justice and Delinquency Prevention that will allow us to expand our cross-age peer mentoring project. The overall goal of this project titled Saving Lives, Inspiring Youth (S.L.I.Y) is to evaluate the effectiveness of community based cross-age mentoring to reduce negative outcomes related to violence exposure/engagement and promote positive development among African-American and Latino youth from four sites serving three low-income, high violence urban neighborhoods engaging youth mentors from the same high-risk environment. In collaboration with several community organizations such as StandUp! HelpOut!, Bright Star Community Outreach, Sue Duncan Children's Center, Telpochcalli Community Fine Arts School, Family Focus, After School Matters, and more, a prospective approach will be implemented to follow cross-age mentor/mentee pairs for one year of mentoring. Quantitative data will be collected pre, post and at a 12 month follow-up. Qualitative data will allow us to investigate what occurred in the mentoring process that helped produce positive outcomes from the cross-age peer mentoring relationships.
