Share2Quit: Web-based Peer-driven Referrals for Smoking Cessation

描述(申请人提供)：虽然戒烟努力取得了一些成功，但吸烟人数的下降已经放缓，特别是在年轻吸烟者中。戒烟热线和戒烟网站等易于传播的干预措施可能会接触到更多的吸烟者。不幸的是，这些干预措施没有得到充分利用。同行驱动的连锁推荐正迅速成为招聘难以接触到的人及其社交网络的首选方法。然而，使用基于网络的连锁转诊来招募患者参加在线健康干预尚未得到广泛研究。因此，在Share2Quit中，我们将测试一套电子连锁转介方法，以增加在线戒烟自我管理干预的机会。我们的总体目标是增加获得戒烟资源的机会。我们将使用Decide2Quit.org(D2Q)进行我们的研究，这是一个现有的基于网络的干预措施。D2Q是目前两项随机试验的核心患者干预措施，这两项试验包括240多家牙科和内科诊所，已经招募了1000多名吸烟者。我们有以下具体目标：1)形成性研究：对40名吸烟者进行有目的的深入访谈，以完善主动链转介工具。2)开发和测试：使用敏捷编程、大声思考访谈和模拟实际干预的小型试点，开发和测试Share2Quit工具。3)干预：评估连锁转诊流程和Share2Quit工具的转诊成功。干预将从最初的一组种子开始，我们估计有800-1200名吸烟者参加。将实施受访者驱动抽样(RDS)的最佳做法，这是一种先进的链式转诊技术，包括创新的WebRDS技术。我们将对转诊成功的预测者进行建模，使用RDS的样本权重来评估系统在目标人群中的成功。我们的发现将大大有助于我们理解在线连锁转诊增加获得服务的潜力及其对结果的影响。

DESCRIPTION (provided by applicant): While cessation efforts have achieved some success, the decline in smoking has slowed, especially among younger smokers. Easily disseminated interventions like Quitlines and smoking cessation websites can potentially reach much greater numbers of smokers. Unfortunately, these interventions are under-utilized. Peer-driven chain referrals are quickly becoming the method of choice for recruiting hard-to-reach persons and their social networks. However, use of web-based chain referrals to recruit patients to online health interventions has not been extensively studied. Thus, in Share2Quit we will test a suite of electronic chain referral approaches to increase access to smoking cessation self-management interventions online. Our overall goal is to increase access to smoking cessation resources. We will conduct our study using Decide2Quit.org (D2Q), an existing web-based intervention. D2Q is the core patient intervention of two current randomized trials that include over 240 dental and physician practices that have already recruited over 1,000 smokers. We have the following specific aims: 1) Formative Research: Conduct in-depth interviews with a purposive sample of 40 smokers to refine proactive chain referral tools. 2) Development and Testing: Using agile programming, think aloud interviews, and mini-pilot mimicking the actual intervention, develop and test the Share2Quit tools. 3) Intervention: Evaluate the chain referral process and the referral success of the Share2Quit tools. The intervention will start with an initial set of seeds and we estimate a sample of 800-1200 smokers. The best practices of respondent-driven-sampling (RDS), an advance chain referral technique, will be implemented, including innovative webRDS techniques. We will model predictors of referral success, using sample weights from RDS to estimate the success of the system in the targeted population. Our findings will contribute significantly to our understanding of the potential of online chain referrals to increase access to services, and the impact on outcomes.
