Data_Sheet_1_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：既往研究指出，手机应用程序（app）可能有助于提高戒烟率。本单组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应用的可操作性与受接受度：吸烟戒烟率。方法：共有来自中国大陆两座城市的180名有戒烟意愿的吸烟者受邀参与本戒烟应用项目，该项目通过智能手机应用提供基于认知行为理论（CBT）的戒烟干预。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期起33天的干预）。在基线阶段（初始安装）、戒烟前阶段以及戒烟后阶段（戒烟日期后的第7、15和33天）评估了项目的可操作性与受接受度，以及吸烟状况。结果：共有163名（90.6%）参与者完成了研究。其中，在各个阶段（基线、戒烟前阶段和戒烟后阶段的第7、15和33天），76%至89%的参与者每天至少登录应用1次；约90%的参与者对应用表示满意。从基线（第一次测量时93%）到项目结束（戒烟日期后33天，即第二次测量时98%）对应用的整体满意度显著提升（p = 0.021）。认为/同意该应用有助于戒烟的参与者比例从基线的69%显著增加到戒烟日期后的第33天97%（p < 0.001）。参与者对大部分（80%至90%）的功能表示满意，尤其是信息功能。意向性治疗分析显示，33天自我报告的连续无烟率占63.9%，而戒烟日期后的第7、15和33天，7天的点无烟率分别为81.7%、87.2%和77.8%。结论：本研究证实了智能手机应用干预在戒烟方面的可操作性与受接受度，并引入了一种新的数字治疗模式，有望克服传统面对面戒烟服务的障碍，并将全国范围内的戒烟服务扩展至更广泛的受众。
