Introduction
The total number of smokers worldwide is increasing,Any smoking early in a quit attempt (a “lapse”) is highly predictive of longer-term return to smoking (“relapse”),There is a lack of effective support to help smokers manage cue-induced cravings. Steady-state medications such as bupropion, Varenicline, and nicotine patches, do not address cue-induced cravings.Meta-analyses pooling smoking cessation smartphone app evaluations have yet to demonstrate a benefit,The Quit Sense app was developed as a passive measurement JITAI for smoking cessation to address the gap in support for managing situational cues to smoke. It is trained by the smoker before their quit attempt starts so the app, and the smoker, can learn their smoking habits, including the locations where they smoke and the smoking cues which precede their smoking whilst they are within these locations. Then, once their quit attempt starts, Quit Sense delivers behavioral support triggered by and tailored to users’ smoking locations and their associated smoking cues. Hence, Quit Sense succeeds in providing “in the moment” support to smokers, including the provision of lapse prevention strategies, and is both engaged with and found to be acceptable.
