Brief Summary
The purpose of this study is to evaluate the effectiveness of the Big Brothers Big Sisters of America (BBBSA) community-based mentoring (CBM) program for prevention of crime and delinquency/conduct problems, including risk and protective factors for these outcomes. Approximately 2,500 youth ages 10-16 will be randomly assigned to either the CBM program or an untreated control group. Study outcomes will be assessed over a 4-year period via both youth- and parent-report surveys and official records of police/court contact (e.g., arrests).
