Study Summary
The goal of this research is to test the Adapt2Quit computer program that uses participant input (message rating on how much the text motivational message might influence one to quit smoking) to select and text motivational messages that are more likely to help a user stop smoking. This Adapt2Quit system will be compared with a quitline facilitation-only control (text messages will be sent to facilitate quitline use). The primary research hypothesis is that the Adapt2Quit recommender-selected messages will be more effective than a texting quitline facilitation-only control for smoking cessation among socioeconomically disadvantaged (SED) smokers.
Primary Outcome
Participants who self-reported no tobacco use in the past 7 days at the 6-month follow-up underwent biochemical verification using the CoVita Smokerlyzer breath carbon monoxide (CO) monitor. Participants with a CO measurement of ≤6 ppm were classified as abstinent; those with a CO measurement of \>6 ppm were classified as tobacco users.
