Can text nudges help smokers with mental illness kick the habit?
NCT ID NCT05952401
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This pilot study tested a program called 'Nudges to Quit' that sends encouraging messages to people with serious mental illness who smoke. The goal was to see if these messages could help them start smoking cessation treatments like counseling or medication. The study involved 59 patients from a community mental health center and compared the nudge program to usual care. Because it was a small early-stage trial, the main focus was on whether the approach is feasible, not yet on whether it actually helps people quit.
