Summary

This pilot trial tests whether a brief, culturally adapted support message sent to a smartphone during moments of high stress can reduce the urge to smoke, vape, or eat in response to stress. About 115 gender and sexual minority adults in Dhaka will receive up to five check-ins per day over 24 days. When stress levels spike, the app randomly sends either a support message or nothing, and participants rate their urge shortly after. The goal is to see if this just-in-time intervention can ease cravings in real time and whether it can be delivered safely and privately in a high-stigma setting.

What this could mean

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

Active substance
Just-in-Time Adaptive Support Message
What this could lead to
If effective, this approach could offer a discreet, on-the-spot tool to help people manage stress-driven urges, potentially reducing smoking and unhealthy eating in high-stigma settings.
What could go wrong
This is a small pilot study, so results may not be conclusive. The effect may be short-lived, and the study does not address the underlying stigma that causes stress.
