Project Northland was a randomized community trial to prevent or delay alcohol use among adolescents. Students in the intervention communities were exposed to a multi-component prevention program in early adolescence and high school. This paper examines the impact of Project Northland on the trajectories of four scales of the adolescent form of the Minnesota Multiphasic Personality Inventory (MMPI-A). Students in the intervention communities demonstrated lower rates of growth of family problems and alcohol/drug use proneness than students in the delayed-program control communities. The results were more robust for baseline non-drinkers. Editors’ Strategic Implications: This experimental study extends the scope of the impact of Project Northland, already recognized as a model substance abuse prevention program by the Substance Abuse and Mental Health Services Administration. The results suggest that focused prevention programs have the potential to impact young adolescents’ lives more broadly. Replication and further examination of the mechanisms by which risk factors and outcomes are modified is necessary, but school administrators and public health officials could learn from this promising program and evaluation.
