Summary

This study explores whether brief, smartphone-delivered coping messages can help college students manage moments of intense emotion, potentially reducing reactive online posting, drinking, and emotional eating. Participants wear a wrist device and answer phone check-ins several times a day for about five weeks. At random moments when emotions seem to be shifting, the app may send a short coping prompt, and the study compares what happens afterward. An optional hair sample is also collected to measure stress hormones and see if they relate to in-the-moment responses.

What this could mean

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

Active substance
Momentary coping prompts delivered via smartphone app
What this could lead to
If effective, this approach could offer a simple, scalable way to help college students manage emotional reactions, potentially reducing impulsive drinking, emotional eating, and online aggression.
What could go wrong
This is a small pilot study, so results may not be conclusive. The coping messages may not have a significant impact, and the findings may not generalize beyond this student population.
