What this research studies

This project partners with 24 youth-serving agencies in Minnesota to deliver the Not a Number (NAN) prevention program to youth considered at risk for commercial sexual exploitation. Agencies will be paired and randomized so some groups receive NAN through a train-the-trainer model while others continue their usual programming, and researchers will compare outcomes across these groups. The team will use community-based participatory methods, collect interviews and implementation data, and pilot test evaluation tools before the full rollout. Over five years the first phase refines methods and the second phase carries out the randomized comparison to learn whether NAN reduces victimization and improves safety-related outcomes.

Who could benefit from this research

Good fit: Ideal participants are children and adolescents served by the participating Minnesota youth-serving agencies who are identified as at risk for commercial sexual exploitation.

Not a fit: Youth who are not connected to the participating agencies, not identified as at risk, or who do not receive the program are unlikely to benefit directly from this project.

Why it matters

Potential benefit: If successful, this program could lower the chance that at-risk youth become victims of commercial sexual exploitation and improve their safety skills.

How similar studies have performed: Some prevention programs have shown promise for improving knowledge and safety behaviors, but Not a Number has not yet been tested in a randomized trial and remains promising but unproven.
