Full eligibility criteria
Study Inclusion Criteria * Must be 18 years of age or older * Must identify as Black/African-American * Must smoke at least 5 cigarettes or cigarette equivalents per day (i.e., cigarettes, cigars, and cigarillos) * Must be willing to use NRT, a smartphone watch and app, and a smoking cessation counselor to help them quit smoking * Must be willing to quit smoking within the next 3 weeks * Must have a CO level of \>6 ppm at app activation. * Are not currently active, defined as engaging in less than 150 minutes of moderate-intensity aerobic physical activity (e.g., brisk walking) or 75 minutes of vigorous-intensity aerobic physical activity (e.g., running or jogging) each week? Study Exclusion Criteria * Does not give permission to administer screening survey * Does not understand or speak English * Is not a U.S. citizen or permanent U.S. resident * Does not use tobacco products * Does not want to provide SSN, residency status, or OUHSC employee status * Is not willing to abstain from smoking marijuana or cannabis during their quit attempt * Is not willing to upload a picture of their tobacco product * Is not ready to quit smoking as defined by scoring 4 or lower on the readiness to quit ladder * Has a medical condition that prevents the use of NRT without approval from a healthcare provider * Has had a serious allergic reaction or side effect from the use of NRT * Does not give permission to collect contact information * Must not be currently active, defined as engaging in less than 150 minutes of moderate-intensity aerobic physical activity (e.g., brisk walking) or 75 minutes of vigorous-intensity aerobic physical activity (e.g., running or jogging) each week.
About the study
The overall objectives of this research proposal, are to (a) create a smartphone application for smoking cessation (i.e., HealthyCells), which will be achieved by integrating two pre-existing evidence-based smartphone interventions, (b) create culturally tailored treatment content (i.e., messages, images, and videos) for African American smokers, and (c) evaluate the feasibility of HealthyCells at addressing smoking and sedentary behavior among African Americans. A pilot sample of African American smokers (N = 15) will briefly use the HealthyCells app and provide critical feedback through semi-structured interviews to refine the smartphone intervention. Once the HealthyCells app is refined, African Americans (N = 30) who are interested in quitting smoking will use the app during a scheduled quit attempt. Starting on the scheduled quit date, HealthyCells will prompt participants to complete twice-daily remote smoking status assessments to earn rewards for abstinence. The app will deliver real-time messages telling participants to stand up and move around during prolonged bouts of sedentary behavior (i.e., ≥ 30 minutes of uninterrupted time spent in a sitting, reclining, or lying posture). Participants will also have on-demand access to culturally tailored information and strategies for remaining abstinent and reducing sedentary behavior within the HealthyCells app. The primary outcomes will be biochemically confirmed point prevalence smoking abstinence at 8 weeks post-quit date, and the difference in sedentary time 7 consecutive days before quitting compared with 7 consecutive days at 8-weeks post-quit, as measured by a research-grade accelerometer.
