Can a smartphone app keep people out of trouble and into treatment?
NCT ID NCT07199374
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing a mobile app called PARCA that helps people on probation or parole set personal goals, manage resources, and track progress. Researchers want to see if using the app helps people start substance use treatment sooner and attend more sessions. The study will enroll 50 people under community supervision and their officers, using surveys and interviews to gather feedback.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- PARCA mobile app (behavioral intervention)
- What this could lead to
- If it works, this could point toward a simple digital tool that helps people on probation start treatment sooner and stay engaged.
- What could go wrong
- This is a very small, early study (50 people) without a control group. The app may not lead to meaningful changes in treatment initiation or supervision outcomes.
