背景：移动技术提供了向个人提供与健康相关的干预措施的潜力，否则这些人将无法亲自接受治疗。短信（短消息服务，SMS），作为最普遍的移动通信形式，是一种很有前途的方法，可以接触到大多数人。目的：本研究的目的是评估通过短信传递的戒烟干预计划的可行性和初步效果。方法：成年参与者（N=60，年龄18-52岁）参加了一个单独的戒烟咨询会议，然后随机分配接受每日不吸烟相关短信（对照条件）或TXT-2-戒烟（TXT）干预。TXT包括根据个人戒烟阶段定制的自动戒烟信息，根据用户要求提供额外支持的专门信息，以及点对点的社会支持网络。采用2（治疗组）x3（时间点）重复测量设计，跨越3个时间点：8周、3个月和6个月，采用广义估计方程分析来评估主要结局（7天点患病率戒断）。结果：戒烟结果显示，在所有随访时间点上，7天点患病率戒烟总体上有显著的组间差异。给予TXT干预的个体，与Mojo组相比，TXT组7天点流行禁欲的几率更高（OR=4.52, 95% CI=1.24, 16.53）。然而，每个时间点的个体比较没有显示出组间的显著差异，可能是由于统计效力降低。通过从传统的面对面招募方法（4.7%收益）转向在线/远程策略（41.7%收益），干预的可行性大大提高。结论：虽然本研究的目的是开发并提供tpt -2- quit系统的初步测试，但这些初步发现提供了有希望的证据，表明基于文本的干预可以成功地应用于不同的成年吸烟者群体。
Background: Mobile technology offers the potential to deliver health-related interventions to individuals who would not otherwise present for in-person treatment. Text messaging (short message service, SMS), being the most ubiquitous form of mobile communication, is a promising method for reaching the most individuals.Objective: The goal of the present study was to evaluate the feasibility and preliminary efficacy of a smoking cessation intervention program delivered through text messaging.Methods: Adult participants (N=60, age range 18-52 years) took part in a single individual smoking cessation counseling session, and were then randomly assigned to receive either daily non-smoking related text messages (control condition) or the TXT-2-Quit (TXT) intervention. TXT consisted of automated smoking cessation messages tailored to individual's stage of smoking cessation, specialized messages provided on-demand based on user requests for additional support, and a peer-to-peer social support network. Generalized estimating equation analysis was used to assess the primary outcome (7-day point-prevalence abstinence) using a 2 (treatment groups) x3 (time points) repeated measures design across three time points: 8 weeks, 3 months, and 6 months.Results: Smoking cessation results showed an overall significant group difference in 7-day point prevalence abstinence across all follow-up time points. Individuals given the TXT intervention, with higher odds of 7-day point prevalence abstinence for the TXT group compared to the Mojo group (OR=4.52, 95% CI=1.24, 16.53). However, individual comparisons at each time point did not show significant between-group differences, likely due to reduced statistical power. Intervention feasibility was greatly improved by switching from traditional face-to-face recruitment methods (4.7% yield) to an online/remote strategy (41.7% yield).Conclusions: Although this study was designed to develop and provide initial testing of the TXT-2-Quit system, these initial findings provide promising evidence that a text-based intervention can be successfully implemented with a diverse group of adult smokers.
