Probation officers as drug counselors: a new way to help teens?
NCT ID NCT03015805
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether juvenile probation officers can deliver a behavioral program called Contingency Management to teens on their caseload who have drug problems. The program uses rewards and counseling to encourage teens to stop using drugs. Researchers measured drug use through urine tests and self-reports over 9 months. The goal was to see if this approach works when delivered by probation officers instead of traditional therapists.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Contingency Management (behavioral intervention)
- What this could lead to
- If successful, this could show that probation officers can effectively deliver drug treatment to teens, expanding access to care.
- What could go wrong
- This is a completed study, but it tested a new delivery method (by probation officers) rather than a new treatment, so impact may be limited. Results may not apply to all settings.
