简介 每年有数百万吸烟者使用互联网寻求戒烟援助；然而，即使是设计最好的网站，大多数吸烟者也很少参与。移动设备的普遍性及其在促进健康行为改变其他领域的依从性方面的有效性，使它们成为解决互联网戒烟干预措施依从性的有前途的工具。大多数成年人都使用短信，短信可以主动鼓励使用基于网络的干预措施。短信还可以与互联网干预相结合，以促进核心互联网干预组件的使用。方法和分析我们确定了短信干预的四个方面，可以提高其在促进遵守基于网络的戒烟计划方面的有效性：个性化、集成、动态定制和信息强度。第一阶段将使用两级全因子设计来测试这四个实验特征对坚持基于网络的干预的影响。主要结果是遵守情况的综合指标，其中包含一般利用率指标（例如登录、页面浏览量）和用于预测戒断的特定功能利用率。参与者将是 N=860 名成年吸烟者，他们在已建立的互联网戒烟计划上注册并参加其短信计划。 II 期将是一项双组随机试验，比较单独基于网络的戒烟计划以及与优化短信干预相结合对 9 个月时 30 天点流行率戒烟的效果。第二阶段的参与者将是 N=600 名成年吸烟者，他们注册使用既定的互联网戒烟计划并注册短信。二次分析将探讨依从性是否介导治疗条件对结果的影响。伦理与传播 该方案经切萨皮克 IRB 批准。我们将通过与方法和设计、结果和探索性分析相关的同行评审手稿和会议演示来传播研究结果。试验注册号 NCT02585206。
Introduction Millions of smokers use the Internet for smoking cessation assistance each year; however, most smokers engage minimally with even the best designed websites. The ubiquity of mobile devices and their effectiveness in promoting adherence in other areas of health behaviour change make them a promising tool to address adherence in Internet smoking cessation interventions. Text messaging is used by most adults, and messages can proactively encourage use of a web-based intervention. Text messaging can also be integrated with an Internet intervention to facilitate the use of core Internet intervention components.Methods and analysis We identified four aspects of a text message intervention that may enhance its effectiveness in promoting adherence to a web-based smoking cessation programme: personalisation, integration, dynamic tailoring and message intensity. Phase I will use a two-level full factorial design to test the impact of these four experimental features on adherence to a web-based intervention. The primary outcome is a composite metric of adherence that incorporates general utilisation metrics (eg, logins, page views) and specific feature utilisation shown to predict abstinence. Participants will be N=860 adult smokers who register on an established Internet cessation programme and enrol in its text message programme. Phase II will be a two-arm randomised trial to compare the efficacy of the web-based cessation programme alone and in conjunction with the optimised text messaging intervention on 30-day point prevalence abstinence at 9months. Phase II participants will be N=600 adult smokers who register to use an established Internet cessation programme and enrol in text messaging. Secondary analyses will explore whether adherence mediates the effect of treatment condition on outcome.Ethics and dissemination This protocol was approved by Chesapeake IRB. We will disseminate study results through peer-reviewed manuscripts and conference presentations related to the methods and design, outcomes and exploratory analyses.Trial registration number NCT02585206.
