A tailored just-in-time adaptive intervention (Smart-T) significantly increased biochemically verified 7-day smoking abstinence at 26 weeks compared to a standard QuitGuide app in low-income adults.
Smart-T users interacted more frequently with the intervention and rated it as more helpful than QuitGuide users.
Both interventions were combined with nicotine replacement therapy, underscoring the added value of the adaptive smartphone support.
No significant differences were observed for 30-day or continuous abstinence outcomes, indicating the need for further optimization of sustained cessation support.
