Summary

This study tested a mobile app called CoQuit that uses cognitive dissonance—the mental discomfort of holding conflicting beliefs—to motivate smokers to quit. 72 adult daily smokers used the app for 25 days, completing activities like writing a letter to a young person about smoking. The app aimed to increase feelings of dissonance and reduce the number of cigarettes smoked per day.

What this could mean

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

Active substance
CoQuit App (a mobile app that uses cognitive dissonance exercises to help people stop smoking)
What this could lead to
If it works, this could point toward a simple, low-cost mobile app that helps people quit smoking by changing how they think about their habit.
What could go wrong
This was a very small, early feasibility study with only 72 participants and no comparison group. The app may not be effective for everyone, and results may not apply to the general population.
