Summary

This study is developing and testing a smartphone app called METS4Vets, designed to help veterans with substance use disorders as they move from residential treatment back into everyday life. The app provides motivational and skills-building support. Researchers are enrolling 30 veterans to see if the app is usable, acceptable, and feasible, and to measure changes in their daily functioning over six months.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
METS4Vets mobile app (behavioral intervention)
What this could lead to
If effective, this app could provide a low-cost, accessible tool to help veterans maintain recovery and improve daily life after leaving residential treatment.
What could go wrong
This is a small, early-stage study focused on usability and feasibility, not on proving the app works. The app may not lead to lasting improvements in substance use or functioning.
