Design outcomes

Primary

MeasureTime frame
The primary outcome will be self-report of not smoking in the 4 weeks prior to the follow up scheduled for 8 weeks since registration, and biochemically verified by saliva cotinine level of <15 ng/mL, or by a saliva anabasine level of <1 ng/ml among those reporting using nicotine replacement therapy or electronic cigarettes. Participants lost to follow up will be presumed to have resumed smoking.

Secondary

MeasureTime frame
1. Self-reported abstinence rates during the 4 weeks prior to the follow-up scheduled for 8 weeks after registration (complete abstinence, and rates of smoking 5 cigarettes or less) 2. Self-reported use of nicotine replacement therapy since the registration, assessed at 8-week follow-up 3. Self-reported use of other cessation medications and support at 8-week follow-up 4. Satisfaction ratings of the intervention at 8-week follow-up 5. Quantitative indices of app use (e.g., number of times the app was opened) 6. Self-reported criteria required for the Russell Standard (RS6): self-reported continuous 6-month abstinence assessed at 7-month follow-up, defined as having no more than 5 cigarettes in the past 6 months and no cigarettes in the previous week 7. Self-reported 7-day point-prevalence abstinence assessed at 7-month follow-up.
