Project DEDUCE

This app is for adults who are taking part in a research study at Duke University on smoking, daily environments, and quitting. It helps you complete brief check-ins on your phone and securely share photos of the places you spend time, so that researchers can better understand how everyday settings influence cravings, smoking, and relapse risk. During the 2-week monitoring period before your quit date, the app will send you short surveys about 10 times per day during your usual waking hours. You will answer a few questions about when you last smoked or vaped, your current urge to smoke, your mood and stress, where you are, whether anyone around you is smoking, and what you are doing. The app will also ask you to take a quick photo of what you see from where you are. Some surveys are slightly longer, and some are very brief, to keep things manageable. You will also be asked to complete a brief survey in the app whenever you smoke, vape, or use another tobacco or nicotine product. These questions focus on what you used, how you were feeling before you used it, and where you were at the time, along with one photo of your surroundings. The information you provide will be combined with data from other participants and analyzed using advanced computer-vision and machine-learning methods. The goal is to identify features of everyday environments that make quitting smoking harder or easier and to guide the development of better future treatments to help people quit. The app itself does not provide medical care or personalized treatment recommendations. If you have questions about your smoking, quitting, or the study, please contact the study team or your healthcare provider.
