Data_Sheet_2_Feasibility and Acceptability of a Cognitive Behavioral Therapy-Based Smartphone App for Smoking Cessation in China: A Single-Group Cohort Study.docx

BackgroundPrevious research has suggested that mobile phone applications (apps) may potentially increase quit rates. The purpose of this single-group cohort study sought to examine the feasibility and acceptability of a novel smartphone-based smoking cessation app designed for smoking cessation in China: smoking quit rate.MethodsA total of 180 smokers from two cities of mainland China with willingness to make a quit attempt were invited to this smoking cessation app program, a cognitive behavioral theory (CBT)-based smoking cessation intervention via a smartphone app. Participants received 37- to 44-day intervention (including 7- to 14-day pre-quit preparation and 33-day intervention from quit date). Feasibility and acceptability of the program, and smoking status were assessed at baseline stage (initial installation), pre-quit stage, and post-quit stage (days 7, 15, and 33 after quit date).ResultsA total of 163 (90.6%) participants completed the study. Among them, 76–89% of the participants logged into the app ≥1 time per day across stages (at baseline, during pre-quit stage, and on days 7, 15, and 33 of post-quit stage); approximately 90% of the participants were satisfied with the app across stages. A significant rise in self-reported overall satisfaction with the app is observed from baseline (93% at Time 1) to the end of the program (98% at Time 2, 33 days after quit date) (p = 0.021). Participants who believed/agreed this app can help them to quit smoking significantly increased from 69% at baseline to 97% at day 33 after quit date (p < 0.001). Participants were satisfied with most (80–90%) of the features, especially the information feature. Intention-to-treat analysis showed that the percentage of 33-day self-reported continuous prevalence abstinence was 63.9%, and 7-day point prevalence abstinence rate was 81.7, 87.2, and 77.8% on days 7, 15, and 33 after quit date, respectively.ConclusionsThis study demonstrated the feasibility and acceptability of the smartphone app intervention for smoking cessation and introduced a new digital treatment model, which is expected to overcome barriers facing accessing traditional in-person smoking cessation services and extend nationwide smoking cessation services in China.

背景：既往研究表明，手机应用程序（APP）可能有助于提高戒烟成功率。本项单一队列研究旨在探讨一款针对中国吸烟者戒烟设计的创新智能手机戒烟APP的可行性和可接受性：戒烟成功率。方法：共计邀请来自中国大陆两座城市的180名有戒烟意愿的吸烟者参与本戒烟APP项目，该干预措施基于认知行为理论（CBT）的戒烟干预，通过智能手机APP进行。参与者接受了37至44天的干预（包括7至14天的戒烟前准备和从戒烟日起的33天干预）。在基线阶段（初始安装）、戒烟前阶段和戒烟后阶段（戒烟日起的第7、15和33天）评估了该项目的可行性和可接受性，以及吸烟状况。结果：共有163名（90.6%）参与者完成了研究。其中，76-89%的参与者在各个阶段（基线、戒烟前阶段以及戒烟日起的第7、15和33天）每天至少登录APP一次；约90%的参与者在各个阶段对APP表示满意。从基线（第1次调查时的93%）到项目结束（戒烟日起第33天的第2次调查时的98%）的自我报告总体满意度显著上升（p = 0.021）。相信/同意该APP能帮助他们戒烟的参与者比例从基线时的69%显著增加到戒烟日起第33天的97%（p < 0.001）。参与者对大多数（80-90%）的功能表示满意，尤其是信息功能。意向治疗分析显示，戒烟日起33天自我报告的连续无烟率占63.9%，而在戒烟日起的第7、15和33天，7天点无烟率分别为81.7%、87.2%和77.8%。结论：本研究证实了智能手机APP干预在戒烟方面的可行性和可接受性，并提出了一种新的数字化治疗模式，有望克服传统面对面戒烟服务的障碍，并扩展中国全国范围内的戒烟服务。
