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 four community organizations: CeaseFire, StandUp! HelpOut!, Lawndale Christian Legal Center, and Enlace, 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 that helped produce positive outcomes from the cross-age peer mentoring relationships.
