The overall goal of the study is to assess the efficacy of using cue exposure delivered via a smartphone application as an adjunct to Tobacco Quitline treatment to improve smoking abstinence.
The aims of the study are: (1) to update a recently developed study-related smartphone application to reduce cravings to smoke to be an engaging, user-friendly treatment tool, and verify user satisfaction; and (2) to test in a randomized controlled trial the efficacy of the app as an adjunct to quitline smoking cessation treatment in improving smoking abstinence compared to the quitline only.

Participants will be asked to use a recently developed study smartphone application to reduce cravings to smoke for a 5-week period. Through the app, participants will be exposed to smoking extinction trials daily. Participants will be encouraged and reminded to complete 2-5 extinction sessions per day. Each session will present 3-8 cues, and each cue will be presented for 20-40 seconds (average amount of extinction per day will be about 10 minutes). Participants will be encouraged to conduct the extinction sessions when high cravings are expected.
Quitline coaches use cognitive behavioral therapy, reinforcement, and principles of self-efficacy to promote effective behavior change. The quitline approach includes 5 key elements: setting a quit date, coping with triggers, effectively using medications, tobacco proofing, and social support. Individuals who enroll in the quitline's multi-call program receive phone calls and NRT.

RECRUITINGSystem Usability Scale (Aim 1)
Participants' perception of usability and learnability of the app will be measured using 10 items on a 5-point Likert scale. Scores range from 0 to 100, with higher scores indicating better usability.
Time frame: At 1 Week
Tobacco Abstinence (Aim 2)
Self-report of no combustible tobacco use in the past 7 days
Time frame: At 6 Months
User Satisfaction (Aim 1)
One Likert scale item will capture participants' satisfaction with the app. The Likert scale is from 1 to 4, with higher score indicating greater satisfaction.
Time frame: At 1 Week

In addition to quitline services, participants will download a study app that will allow them to track smoking urges and abstinence. After 48 hours of self-reported abstinence, those in the intervention group will be exposed to smoking extinction trials through the study smartphone app.
