This pilot study assessed the feasibility, acceptability, and preliminary efficacy of a smoking cessation intervention that used mobile phones to remotely deliver reinforcements contingent on tobacco abstinence (contingency management [CM]) and weekly in-person cognitive-behavioral therapy to adolescent smokers. Daily adolescent smokers (N = 15; 12 completed study procedures, 3 dropped out) were recruited to participate in a 4-week study. During the first 2 weeks, daily text messages sent at random times prompted participants to transmit a video of themselves providing a carbon monoxide (CO) sample. During the last 2 weeks, text messages sent on 3 randomly chosen days each week prompted participants to transmit a video of themselves providing a saliva sample. Negative samples (CO ≤8 ppm; cotinine ≤100 ng/ml) were reinforced with monetary incentives. Feasibility was assessed using the number of on-time, valid videos, and acceptability was determined using participant perceptions of the intervention. Seven-day point-prevalence (PP) abstinence (self-reported abstinence, cotinine <100 ng/ml) was assessed at end of treatment (EOT) and at a 1-month follow-up. The study findings indicate that remote delivery of CM using mobile phones was feasible (85.8% of the CO videos and 67% of the saliva cotinine videos were on time) and acceptable (positive perceptions of the CM procedures). Seven-day PP was 60% at EOT and 46.7% at the follow-up. Although larger randomized controlled trials are needed to evaluate efficacy, this pilot study suggests that the use of mobile phones to deliver CM for smoking cessation among adolescent smokers was acceptable and feasible.

这项试点研究评估了一种戒烟干预措施的可行性、可接受性和初步疗效。该干预措施利用手机远程提供基于烟草戒断的强化措施（应急管理[CM]），并为青少年吸烟者提供每周一次的面对面认知行为疗法。招募了每日吸烟的青少年（N = 15；12人完成研究程序，3人退出）参与为期4周的研究。在前两周，随机时间发送的每日短信促使参与者发送自己提供一氧化碳（CO）样本的视频。在最后两周，每周随机选择的3天发送的短信促使参与者发送自己提供唾液样本的视频。阴性样本（CO≤8 ppm；可替宁≤100 ng/ml）会得到金钱奖励。使用按时、有效的视频数量评估可行性，通过参与者对干预措施的看法确定可接受性。在治疗结束时（EOT）和1个月随访时评估7天点患病率（PP）戒烟情况（自我报告戒烟，可替宁<100 ng/ml）。研究结果表明，使用手机远程提供CM是可行的（85.8%的CO视频和67%的唾液可替宁视频按时提交）且可接受的（对CM程序有积极看法）。EOT时7天PP为60%，随访时为46.7%。尽管需要更大规模的随机对照试验来评估疗效，但这项试点研究表明，使用手机为青少年吸烟者提供CM进行戒烟是可接受且可行的。（PsycINFO数据库记录）
