Addressing Tobacco Use Disparities through an Innovative Mobile Phone Intervention: The textto4gosmokelesstobacco

 描述(申请人提供)：美国农村是一个易患烟草相关疾病的高危群体。无烟烟草在美国农村地区的使用率很高，为11%，在过去十年中并没有显著下降。想要戒烟的美国农村人几乎没有什么创新的干预措施。在这一人群中，这是一个严重错失的控烟机会。计划的逐步减少(SGR)可能是帮助无烟烟草使用者戒烟的有效干预措施，而且已经进行了最低限度的研究。通过短信服务(SMS)传递SGR干预措施是增加无烟戒烟干预措施在农村人口中覆盖范围的一种创新方式。我们提出了一项为期3年的试点随机对照试验，以评估通过短信短信和短信支持短信进行SGR干预在减少农村人口无烟烟草使用方面的可行性、可接受性和初步效果。SGR小组(n=60)将收到通过短信短信和短信支持短信提供的为期四周的SGR计划。对照组(n=30)将收到帮助戒烟的短信支持。我们将使用多种招募方法来获得我们的样本，并将使用2：1治疗分配策略，以确保我们在干预组中有足够的样本来为未来的研究产生可靠的效应大小。每个参与者的主要结果将是：1)阅读信息的比例(可行性)；2)接受干预的有用性评级(可接受)；3)在3个月和6个月时戒烟(初步疗效)。这将是第一次使用SGR对无烟烟草使用者进行短信干预，目标是无法获得创新和有效干预的农村无烟烟草使用者。如果成功，这项研究可以很容易地传播给农村无烟烟草使用者，帮助戒烟，从而有助于减少与烟草有关的健康差距。

 DESCRIPTION (provided by applicant): Rural Americans are a vulnerable group at high risk for tobacco-related illness. Smokeless tobacco use is high among rural Americans at 11% and has not decreased significantly in the past decade. Rural Americans who want to quit have access to few innovative interventions. This is a significant missed opportunity for tobacco control in this population. Scheduled Gradual Reduction (SGR) may be an effective intervention to help smokeless tobacco users quit and has been minimally studied. Delivering SGR interventions via Short Message Service (SMS) text messaging is an innovative way to increase reach of smokeless tobacco cessation interventions in rural populations. We propose a 3-year pilot randomized controlled trial to evaluate the feasibility, acceptability and preliminary efficay of a SGR intervention via SMS text messaging plus SMS Support Messages in decreasing smokeless tobacco use in a rural population. The SGR group (n=60) will receive a four week SGR program delivered via SMS text messages plus SMS support messages. The control group (n=30) will receive SMS support messages to aid in quitting. We will use a variety of recruitment methods to obtain our sample and will use 2:1 treatment allocation strategy to be sure we have an adequate sample in the intervention group to generate reliable effect sizes for future studies. Primary outcomes for each participant will be: 1) proportion of messages read (feasibility); 2) ratings of the usefulness of the intervention received (acceptability) and 3) smokeless tobacco cessation at 3 and 6 months (preliminary efficacy). This will be the first SMS texting intervention using SGR with smokeless tobacco users targeting rural smokeless tobacco users who lack access to innovative and effective interventions. If successful, this study can be easily disseminated to rural smokeless tobacco users to aid in cessation, thus helping to decrease tobacco related health disparities.
