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.

Inclusion Criteria:

• Current smoker
• Socioeconomically disadvantaged (SED) (using the following criteria: unemployed or underemployed, low income as defined by the federal poverty level guidelines, uninsured or underinsured, and/or have less than a high school education)
• English-speaking
• Active in care (at least two clinical visits in the last year)
• Have a texting-enabled cell phone

Exclusion Criteria:

• Not a current smoker
• Adults unable to consent
• Individuals who are not yet adults (infants, children, teenagers)
• Prisoners
• Pregnant women
• Pilot study participants

After completing the screening, informed consent, and baseline data collection, study staff will enter the participant identification number and participant mobile phone number from the survey into an online system, and the system will assign allocation based on the randomization table. Using this technique, both smokers and the staff will be blinded to allocation during the initial session. Then, the research staff will be un-blinded to provide personalized training for intervention and control (note that staff who complete follow-up will be different and blinded to group assignment).
