Cigarette smoking is the leading preventable cause of death and illness in the United States. We tested the usability, acceptability, and efficacy of a smartphone‐based contingency management treatment to promote cessation. We used a nonconcurrent multiple‐baseline design. Participants (N = 14) provided breath carbon monoxide (CO) samples by using a CO meter that was connected to the user's smartphone. An app (mMotiv8) housed on participants' smartphones automatically captured pictures of the CO sampling procedure to validate the end user's identity, and it prompted submissions via a push message delivered to participants' smartphones. Participants earned a $10 incentive for daily abstinence, which was added to a reloadable debit card. Overall, 4% of the CO samples were negative during baseline, and 89% were negative during treatment. Self‐reported usability and acceptability were high, and 85% of the prompted samples were submitted. A smartphone intervention could be scalable and reduce the health consequences and costs associated with cigarette smoking, particularly in rural and low‐income populations.

mMotiv8：一种基于智能手机的应急管理干预措施，以促进戒烟

在美国，吸烟是导致死亡和疾病的主要可预防原因。我们测试了基于智能手机的应急管理治疗以促进戒烟的可用性、可接受性和有效性。我们使用了非并发多基线设计。参与者 ( N= 14) 通过使用连接到用户智能手机的 CO 测量仪提供呼吸一氧化碳 (CO) 样本。安装在参与者智能手机上的应用程序 (mMotiv8) 自动捕获 CO 采样过程的图片以验证最终用户的身份，并通过发送到参与者智能手机的推送消息提示提交。参与者每天禁欲可获得 10 美元的奖励，并将其添加到可重新加载的借记卡中。总体而言，4% 的 CO 样本在基线期间呈阴性，89% 在治疗期间呈阴性。自我报告的可用性和可接受性较高，提交了 85% 的提示样本。智能手机干预可以扩展并减少与吸烟相关的健康后果和成本，特别是在农村和低收入人群中。
