Objective To determine the efficacy smartphone application based on acceptance commitment therapy (ACT) vs National Cancer Institute US clinical practice guidelines (USCPG). Design, Setting, Participants A 2-group, stratified, double-blind, individually randomized trial was conducted from May 27, 2017, September 28, 2018, among 2415 adult cigarette smokers (n = 1214 ACT-based group n = 1201 USCPG-based group) with 3-, 6-, 12-month postrandomization follow-up. The study prespecified in protocol. Follow-up data collection started August 26, ended at last participant’s follow-up survey December 23, 2019. Data were analyzed February 25 April 3, 2020. primary analysis performed complete-case basis, intent-to-treat missing as multiple imputation sensitivity analyses. Interventions iCanQuit, an application, which taught triggers, QuitGuide, avoidance triggers. Main Outcomes Measures outcome self-reported 30-day point prevalence abstinence (PPA) 12 months after randomization. Secondary outcomes 7-day PPA randomization, prolonged abstinence, 3 6 imputed or coded smoking, all tobacco products (including e-cigarettes) Results (1700 women [70.4%]; 1666 White individuals [69.0%] 868 racial/ethnic minorities [35.9%]; mean [SD] age enrollment, 38.2 [10.9] years) 50 states. 3-month retention rate 86.7% (2093), 6-month 88.4% (2136), 87.2% (2107). For follow-up, iCanQuit participants had 1.49 times higher odds quitting compared QuitGuide (28.2% [293 1040] 21.1% [225 1067]; ratio [OR], 1.49; 95% CI, 1.22-1.83;P Conclusions Relevance This provides that, more efficacious thus can be impactful treatment option.
