Official title

Personalized Smoking Relapse Prevention Delivered in Real-Time Via Just-in-Time-Adaptive Interventions

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

A small-scale randomized controlled trial (RCT) will pilot test a personalized JITAI designed to guide delivery of fast acting nicotine replacement therapy (NRT; lozenge) in real-time, to prevent smoking relapse. Specifically, a smartphone application (app), will integrate pre-quit smoking data with objective location data captured via global positioning system (GPS) to establish relapse risk (hotspot) algorithms. During a quit attempt, the GPS-enabled app (QuitBuddy) will detect proximity to hotspots and deliver NRT prompts, all of which will occur automatically and prior to exposure. Thus, QuitBuddy will optimize NRT use to prevent cue-provoked cravings known to undermine sustained abstinence, thereby repurposing this evidence-based cessation medication to promote relapse prevention. QuitBuddy will be tested against standard care (NRT with brief instructions). Two versions of QuitBuddy will be tested, which will differ only in how hotspot algorithms are derived: retrospectively from locations recalled at the onset of a quit attempt (QuitBuddy-Recall) or based on real-time EMA completed pre-quit (QuitBuddy).
