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1200万美国人从事无烟烟草（ST）的习惯使用，尽管大多数人希望退出，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由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戒烟网站。我们注册了2,523个ST用户，并发现该网站有效，特别是对于那些最常使用该网站的人来说。基于这一经验，我们认为增加咀嚼者与该计划的参与可能会提高其有效性。探索以增强计划参与度的途径是使用社会支持。绝大多数的St用户（“咀嚼”）是男性，他们的大多数妻子和家庭伴侣都渴望辞职。尽管对吸烟者的社会支持知之甚少，但对ST用户的社会支持知之甚少。在这项发展研究中，我们将测试将合作伙伴支持部分添加到我们的网站中的可行性，以增加咀嚼者的注册和参与该计划。目的：本研究的主要目的是测试：1）通过印刷和广播媒体和互联网招募女性支持者的可行性，以帮助他们鼓励他们鼓励他们的男性ST-Using Partners参与退出计划。这项可行性研究将估计将在未来的随机试验中使用的支持者的比例。 2）合作伙伴支持部分对男性咀嚼者使用Chewfree.com自助戒烟计划的有效性。主要结果指标将是ST用户与该程序的参与，这是通过他登录程序来衡量的。方法：我们计划使用我们的创新和验证的方法来招募944名妇女，并将其随机招募到两个条件之一：1）控制条件将模仿其妻子或家庭伴侣将男性ST用户自然化转介到Web资源中。 2）在支持条件下，我们还将为妻子/合作伙伴提供有关如何支持咀嚼者退出的建议，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。在此R21期间，我们将评估与男性咀嚼的女性伴侣招募和干预的可行性，并评估其信念，态度和行为的变化。措施：我们的主要结果将是通过不引人注目的Web日志测量的程序中咀嚼程序中无需咀嚼网站的访问。在入学后6周和4.5个月的邮寄调查中，将评估咀嚼者与戒烟相关的行为以及支持，自我效能和关系动态的变化，以获得未来研究的效果大小。为了获得效果大小的估计，我们还将评估干预措施对设定戒烟日期，停止尝试和烟草停止率的影响。好处：拟议的研究将：通过明确关注戒烟和男性用户/女性支持者Dyad的特定动态来添加社会支持文献；协助ST用户的合作伙伴进行技能培训和社会支持，以及；增强我们有效的ST戒烟计划的覆盖范围和有效性。争取和增强配偶或国内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。公共卫生相关性：在有效的基于网络的无烟烟草干预的背景下，这项发展研究将测试与男性无烟烟草使用者的女性伴侣进行介入的可行性。
