背景：首个针对成人戒烟的智能手机应用程序（SmartQuit 1.0）的随机试验揭示了预测戒烟的关键特征。这些发现指导了这个基于接受和承诺治疗（ACT）的应用程序（SmartQuit 2.0）的修订，该应用程序主要用于检查参与者的接受性，短期戒烟和减少，以及计划完成，戒烟和减少之间的关系。其次，将结果与SmartQuit1.0试验进行描述性比较。方法：招募成年参与者（78%为女性，25%为高中及以下学历，30%为失业）加入SmartQuit 2.0的单臂先导试验（N=99），随访2个月（保留率85%）。结果：在接受度方面，84%的参与者对SmartQuit 2.0感到满意（SmartQuit1.0为59%），73%的人会向朋友推荐（SmartQuit1.0为48%），81%的人认为ACT练习对戒烟有用（SmartQuit1.0为44%）。在2个月的随访中，7天戒烟率为21%（与SmartQuit1.0相比为23%），30天戒烟率为11%（与SmartQuit1.0相比为13%），75%的参与者减少了吸烟频率（与SmartQuit1.0相比为57%）。在项目完成者（占总样本的24%）中，戒烟率为7天戒烟率为33%，30天戒烟率为28%，88%的参与者减少了吸烟频率。结论：修改后的应用程序具有较高的用户接受度，适度的戒烟率和较高的吸烟率。程序的完成可能是提高应用程序有效性的关键。2016爱思唯尔爱尔兰有限公司版权所有。
Background: The first randomized trial of a smartphone application (app) for adult smoking cessation (SmartQuit 1.0) revealed key features that predict cessation. These findings guided the revision of this Acceptance & Commitment Therapy (ACT)-based application (SmartQuit 2.0), which was primarily tested to examine participant receptivity, short-term cessation and reduction, and the relationship between program completion, smoking cessation and reduction. Secondarily, outcomes were descriptively compared with the SmartQuit1.0 trial.Method: Adult participants (78% female, 25% with high school or less education, 30% unemployed) were recruited into the single-arm pilot trial (N=99) of SmartQuit 2.0 with a two-month follow-up (85% retention).Results: Regarding receptivity, 84% of participants were satisfied with SmartQuit 2.0 (vs. 59% for SmartQuit1.0), 73% would recommend it to a friend (vs. 48% for SmartQuit1.0), 81% found the ACT exercises useful for quitting (vs. 44% for SmartQuit1.0). At the 2-month follow-up, the quit rates were 21% for 7-day point prevalence (vs. 23% for SmartQuit1.0), 11% for 30-day point prevalence (vs. 13% for SmartQuit1.0), and 75% of participants reduced their smoking frequency (vs. 57% for SmartQuit1.0). Among program completers (24% of total sample), the quit rates were 33% for 7-day point prevalence, 28% for 30-day point prevalence, and 88% of participants reduced their smoking frequency.Conclusions: The revised app had high user receptivity, modest quit rates, and high smoking reduction rates. Program completion may be key to boosting the app's effectiveness. (C) 2016 Elsevier Ireland Ltd. All rights reserved.
