A nudge at the right moment: can a 30-second message curb emotional reactions?
NCT ID NCT07789314
First seen Aug 27, 2026 · Last updated Aug 28, 2026 · Updated 1 time
Summary
This pilot study tests whether short coping messages sent to a smartphone can reduce reactive behaviors in college students during moments of emotional stress. Participants wear a wrist device and answer brief check-ins several times a day for about five weeks. At random moments, the app may send a one-to-three-sentence message using techniques like perspective-taking or urge surfing. Researchers compare what participants do in the hours after receiving a message versus not receiving one, focusing on urges to post online, drink alcohol, or eat in response to emotions.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Brief coping messages delivered via smartphone app
- What this could lead to
- If it works, this approach could offer a simple, scalable way to help college students manage emotional impulses and reduce reactive behaviors like posting while upset or stress eating.
- What could go wrong
- This is a small pilot study, so the effects may be small or hard to measure. The messages might not change behavior in real-world settings, and results may not apply beyond this group of students.
