短信（即短消息服务）戒烟干预措施在高收入国家已证明有效，但在包括越南在内的低收入和中等收入国家的研究较少。本研究的目的是评估适用于越南吸烟者的全自动双向短信戒烟干预的可行性、可接受性和初步疗效。本研究分三个阶段进行。在第一阶段，我们从美国的短信戒烟计划（即，SmokefreeTXT和Text2Quit）改编了短信库。适应过程包括7个焦点小组，涉及58名吸烟者，以提供有关烟草使用文化相关模式的数据，并评估信息偏好。在第二阶段，我们对40名吸烟者进行了短信干预的单臂试验，随后对10名参与者进行了深入访谈，以告知短信库的其他变化。在第三阶段，我们对100名吸烟者进行了两组随机对照试验（RCT）。参与者要么接受短信项目（干预组，n=50），要么接受每周吸烟状况短信评估（对照组，n=50）。6周的短信计划包括2周的戒烟前期和4周的戒烟后期。参与者每天收到2到4条自动信息。主要结果是参与和可接受性，在6周（干预结束）时进行评估。我们在第6周和第12周进行生化评估，确认戒烟。干预后的深度访谈探讨了干预组随机抽样的16名参与者的用户体验。两组参与者都报告了高参与度和可接受性。参与者报告说，干预组的平均使用时间为36.4天（SD 3.4），对照组的平均使用时间为36.0天（SD 3.9）。干预组的50名参与者中有4人（8%）重置了戒烟日期，19人（38%）发短信发送关键字TIPS。两组的大多数参与者都报告说他们总是或经常阅读短信。与对照组相比，干预组中更高比例的参与者报告对该计划感到满意（98%[49/50]对82%[41/50]）。生物化学验证的戒断在干预组6周时更高（20% [10/50]vs 2% [1/50]； P= 0.01），但在12周时效果不显著（12% [6/50]vs 6% [3/50]； P= 0.49）。随机对照试验结束后进行的深入访谈建议对该计划进行额外的修改，包括调整信息的时间，增加更多与该计划互动的机会，并更加强调描述吸烟危害的信息。该研究支持了针对越南吸烟者的短信计划的可行性和可接受性。未来的研究需要评估，通过额外的修改，该计划是否与长期禁欲有关。ClinicalTrials.gov NCT03219541;https://clinicaltrials.gov/ct2/show/NCT03219541
Text message (ie, short message service, SMS) smoking cessation interventions have demonstrated efficacy in high-income countries but are less well studied in low- and middle-income countries, including Vietnam. The goal of the research is to assess the feasibility, acceptability, and preliminary efficacy of a fully automated bidirectional SMS cessation intervention adapted for Vietnamese smokers. The study was conducted in 3 phases. In phase 1, we adapted the SMS library from US-based SMS cessation programs (ie, SmokefreeTXT and Text2Quit). The adaptation process consisted of 7 focus groups with 58 smokers to provide data on culturally relevant patterns of tobacco use and assess message preferences. In phase 2, we conducted a single-arm pilot test of the SMS intervention with 40 smokers followed by in-depth interviews with 10 participants to inform additional changes to the SMS library. In phase 3, we conducted a 2-arm pilot randomized controlled trial (RCT) with 100 smokers. Participants received either the SMS program (intervention; n=50) or weekly text assessment on smoking status (control; n=50). The 6-week SMS program consisted of a 2-week prequit period and a 4-week postquit period. Participants received 2 to 4 automated messages per day. The main outcomes were engagement and acceptability which were assessed at 6 weeks (end of intervention). We assessed biochemically confirmed smoking abstinence at 6 weeks and 12 weeks. Postintervention in-depth interviews explored user experiences among a random sample of 16 participants in the intervention arm. Participants in both arms reported high levels of engagement and acceptability. Participants reported using the program for an average of 36.4 (SD 3.4) days for the intervention arm and 36.0 (SD 3.9) days for the control arm. Four of the 50 participants in the intervention arm (8%) reset the quit date and 19 (38%) texted the keyword TIPS. The majority of participants in both arms reported that they always or usually read the text messages. Compared to the control arm, a higher proportion of participants in the intervention arm reported being satisfied with the program (98% [49/50] vs 82% [41/50]). Biochemically verified abstinence was higher in the intervention arm at 6 weeks (20% [10/50] vs 2% [1/50]; P=.01), but the effect was not significant at 12 weeks (12% [6/50] vs 6% [3/50]; P=.49). In-depth interviews conducted after the RCT suggested additional modifications to enhance the program including tailoring the timing of messages, adding more opportunities to interact with the program, and placing a greater emphasis on messages that described the harms of smoking. The study supported the feasibility and acceptability of an SMS program adapted for Vietnamese smokers. Future studies need to assess whether, with additional modifications, the program is associated with prolonged abstinence.
