NCT ID NCT07070414
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to improve a short motivational conversation to help young adults (ages 18-25) who were injured in an assault and also misuse alcohol or cannabis. Researchers will interview and survey 50 participants from a hospital violence intervention program to understand how confident they feel about changing their substance use and how their social circle influences them. The goal is to adapt the conversation and test whether it is feasible and acceptable in an emergency department setting.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Brief Negotiation Interview intervention (BNI) (adapted)
- What this could lead to
- If successful, this could lead to a practical, brief conversation tool that emergency departments can use to help young adults reduce risky substance use after an assault.
- What could go wrong
- This is a very early feasibility study with only 50 participants, so results may not apply broadly. The intervention is behavioral and may not work for everyone.
