DESCRIPTION (provided by applicant): Approximately 12 million Americans engage in the habitual use of smokeless tobacco (ST), and although most wish to quit, many lack resources. In order to meet this need, the investigators recently completed a randomized clinical trial, funded by the National Cancer Institute, to develop and evaluate the ChewFree.com ST cessation website. We enrolled 2,523 ST users and found the site to be effective, especially for those who were most engaged in using the web site. Based on this experience, we believe that increasing chewers' engagement with the program could increase its effectiveness. One avenue to explore for enhancing program engagement is the use of social support. The vast majority of ST users ("chewers") are male, and most of their wives and domestic partners are eager for them to quit. Although much is known about social support for smokers, little is known about social support for ST users. During this developmental research study, we will test the feasibility of adding a partner support component to our web site in an effort to increase chewers' enrollment in, and engagement with, the program. Objectives: The primary aims of this study are to test the: 1) feasibility of recruiting female supporters via print and broadcast media and the Internet to a program aimed at helping them encourage their male ST-using partners to engage in a quitting program. This feasibility study will provide estimates of proportions of supporters who will enroll, for use in a future randomized trial and; 2) effectiveness of a partner support component on male chewers' use of the ChewFree.com self-help ST cessation program. The primary outcome measure will be ST users' engagement with the program, as measured by his logging on to the program. Methods: We plan to use our innovative and proven methods to recruit 944 women, and randomize them to one of two conditions: 1) The Control Condition will emulate the naturalistic referral of a male ST user to web resources by his wife or domestic partner. 2) In the Support Condition, we will also give the wife/partner advice on how to support the chewer in quitting, and provide her with her own social support network in the form of online peer and expert forums. During this R21, we will assess the feasibility of recruiting and intervening with female partners of male chewers and with assessing changes in their beliefs, attitudes, and behavior. Measures: Our primary outcome will be chewers' access of the ChewFree web site within the program, as measured via unobtrusive web logs. Chewers' cessation-related behavior and changes in support, self- efficacy, and relationship dynamics will be assessed by mailed surveys at 6 weeks and 4.5 months post- enrollment to obtain effect sizes for future research. To obtain effect size estimates, we will also assess the effect of the intervention on setting a quit date, cessation attempts, and rates of tobacco cessation. Benefits: The proposed research will: add to the social support literature by focusing explicitly on ST cessation and the specific dynamics of the male-user/female-supporter dyad; assist partners of ST users with skills training and social support, and; enhance the reach and effectiveness of our effective ST cessation program. Enlisting and enhancing the natural support of a spouse or domestic partner may increase the engagement and success of smokeless tobacco users in cessation programs. PUBLIC HEALTH RELEVANCE: This developmental study will test the feasibility of the additive effects of intervening with the female partners of male smokeless tobacco users, in the context of an effective web-based smokeless tobacco intervention.

描述（由申请人提供）：大约有1200万美国人习惯性使用无烟烟草（ST），尽管大多数人希望戒烟，但许多人缺乏资源。为了满足这一需求，研究人员最近完成了一项由美国国家癌症研究所资助的随机临床试验，以开发和评估ChewFree.com ST停止网站。我们招募了2,523名ST用户，发现该网站是有效的，特别是对那些最热衷于使用该网站的人。基于这一经验，我们认为，增加咀嚼者对该计划的参与可以提高其有效性。探索提高项目参与度的一个途径是利用社会支持。绝大多数ST使用者（“咀嚼者”）是男性，他们的大多数妻子和家庭伴侣都渴望他们戒烟。虽然很多人知道吸烟者的社会支持，很少有人知道ST用户的社会支持。在这项发展研究中，我们将测试在我们的网站上添加一个合作伙伴支持组件的可行性，以增加咀嚼者在该计划中的注册和参与。目的：本研究的主要目的是测试：1）通过印刷和广播媒体以及互联网招募女性支持者参加旨在帮助她们鼓励其使用ST的男性伴侣参加戒烟计划的可行性。这项可行性研究将提供将登记的支持者比例的估计，用于未来的随机试验; 2）伴侣支持组件对男性咀嚼者使用ChewFree.com自助ST停止计划的有效性。主要的结果测量将是ST用户对该计划的参与，通过他登录该计划来测量。研究方法：我们计划使用我们的创新和成熟的方法来招募944名女性，并将她们随机分配到两个条件之一：1）控制条件将模仿男性ST用户通过其妻子或家庭伴侣自然地推荐网络资源。2)在支持条件中，我们还将向妻子/伴侣提供如何支持咀嚼者戒烟的建议，并以在线同行和专家论坛的形式为她提供自己的社会支持网络。在R21期间，我们将评估招募和干预男性咀嚼者的女性伴侣的可行性，并评估他们的信仰，态度和行为的变化。措施：我们的主要成果将是咀嚼者在程序中访问ChewFree网站，通过不引人注目的网络日志进行测量。将在入组后6周和4.5个月通过邮寄调查评估咀嚼者的戒烟相关行为以及支持、自我效能和关系动态的变化，以获得未来研究的效应量。为了获得效应量估计值，我们还将评估干预措施对设定戒烟日期、戒烟尝试和戒烟率的影响。优点：拟议的研究将：通过明确关注ST戒烟和男性使用者/女性支持者二元体的具体动态来增加社会支持文献;通过技能培训和社会支持来帮助ST使用者的合作伙伴;以及;提高我们有效的ST戒烟计划的覆盖面和有效性。争取和加强配偶或家庭伴侣的自然支持可能会增加无烟烟草使用者在戒烟计划中的参与和成功。公共卫生关系：这项发展性研究将测试在有效的基于网络的无烟烟草干预的背景下，对男性无烟烟草使用者的女性伴侣进行干预的附加效应的可行性。
