What this trial studies

This intervention provides justice-involved people with a smartphone app that uses motivational interviewing and cognitive behavioral techniques to guide problem-solving, goal selection, progress tracking, and point-based incentives. Supervising officers can view clients' goals, progress, and accumulated points to inform supervision. The study enrolls justice-involved individuals who report drug use and their supervising officers at two county community supervision sites and follows app use with periodic surveys and interviews. Surveys and qualitative interviews will be used to understand user experience and identify ways to improve treatment connections and goal achievement.

Who should consider this trial

Good fit: Ideal candidates are adults on probation or parole who report recent drug use, have access to a smartphone, and are supervised at the participating Travis County (Austin) or Dallas County (Dallas) sites, with supervising officers at those sites also participating.

Not a fit: People with serious untreated mental health disorders, those without reliable smartphone access, or officers not actively supervising at the participating sites may not benefit from this intervention.

Why it matters

Potential benefit: If successful, PARCA could increase treatment engagement and goal achievement and reduce supervision violations and recidivism among participants.

How similar studies have performed: Mobile interventions using motivational interviewing and cognitive behavioral techniques have shown mixed but promising results for substance use, while their specific use within probation/parole supervision is relatively novel.
