吸烟是最大的公共卫生威胁之一。智能手机应用程序为实时支持戒烟提供了新的有希望的机会。这项随机对照试验调查了一个应用程序的有效性,该应用程序鼓励个人在日常生活中在社交网络成员(好友)的帮助下戒烟。
这项研究的目的是测试SmokeFree好友应用程序与对照组的有效性,对照组以自我报告的戒烟和一氧化碳(CO)验证的戒烟为主要结果,而每日吸烟的自我报告(CPD)为次要结果。
共有162名吸烟的成年人参加了这种单盲活动,双臂,平行组,密集的纵向随机对照试验。大约在一个自我设定的戒烟日期(即,自我设定的退出日期前7天,之后20天)和6个月后,干预组和对照组的参与者在日终日记中报告每日戒烟和CPD.通过每日呼出CO评估验证每日禁烟。此评估是通过显示呼出CO的结果的应用程序进行的,从而解决了两组的自我监控问题。此外,干预组中的参与者使用了SmokeFree好友应用程序,一个多组件的应用程序,促进社会支持从一个朋友的选择。
两组参与者从基线到6个月随访时CPD均显著降低。多水平分析显示,在戒烟日期和3周后,对自我报告和共同验证的每日禁烟没有显着干预作用。然而,干预组在戒烟日和3周后的CPD低于对照组。在戒烟日期后6个月,两组之间的任何结果指标均未发现显着差异。总的来说,观察到低应用程序参与度和低感知有用性。
尽管对吸烟量有一些令人鼓舞的短期发现,SmokeFree好友应用程序在自我监测控制条件之外对戒烟没有有益的影响。未来的研究应该研究是否可以有效地刺激支持过程以及如何改善应用程序的使用以更好地实现这一目标。

Tobacco smoking is one of the biggest public health threats. Smartphone apps offer new promising opportunities for supporting smoking cessation in real time. This randomized controlled trial investigated the effectiveness of an app that encourages individuals to quit smoking with the help of a social network member (
buddy) in daily life.
The objective of this study is to test the effectiveness of the SmokeFree
buddy app compared with a control group with self-reported smoking abstinence and carbon monoxide (CO)-verified smoking abstinence as primary outcomes and self-reports of smoked cigarettes per day (CPD) as a secondary outcome.
A total of 162 adults who smoked participated in this single-blind, two-arm, parallel-group, intensive longitudinal randomized controlled trial. Around a self-set quit date (ie, 7 days before the self-set quit date and 20 days after) and 6 months later, participants of the intervention and control groups reported on daily smoking abstinence and CPD in end-of-day diaries. Daily smoking abstinence was verified via daily exhaled CO assessments. This assessment was administered via an app displaying results of exhaled CO, thus addressing self-monitoring in both groups. In addition, participants in the intervention group used the SmokeFree
buddy app, a multicomponent app that facilitates social support from a
buddy of choice.
A significant reduction in CPD from baseline to the 6-month follow-up was observed among participants in both groups. Multilevel analyses revealed no significant intervention effect on self-reported and CO-verified daily smoking abstinence at the quit date and 3 weeks later. However, CPD was lower at the quit date and 3 weeks later in the intervention group than in the control group. No significant differences between groups were found for any outcome measures 6 months after the quit date. Overall, low app engagement and low perceived usefulness were observed.
Despite some encouraging short-term findings on the amount of smoking, the SmokeFree
buddy app did not have beneficial effects on smoking abstinence over and above the self-monitoring control condition. Future studies should examine whether and what support processes can be effectively stimulated and how app use can be improved to better achieve this goal.
