Tailoring Depth in Web-based Smoking Interventions

描述(由申请人提供)：虽然在许多研究中研究了以印刷品为基础的、量身定做的戒烟干预措施的理论基础和有效性，但很少有关于通过万维网提供的计算机定制戒烟干预措施的有效性的研究。此外，公共卫生传播的研究人员对裁剪的有效成分知之甚少，这些成分有助于其有效性。 这个项目建议研究潜在的活性成分的重要性：剪裁的深度。剪裁深度指的是剪裁的细节水平和基于理论的剪裁结构之间的相互作用。低深度的干预可能会产生数以千计的信息组合，而高深度的计划可能会产生数十亿种变化。深度干预可以产生广泛定制的戒烟信息，但它们能带来更好的结果吗？开发这样全面的干预措施值得花费时间和精力吗？在对3000名吸烟者进行的随机1x3析因设计中，这项研究将比较低、中、高深度裁剪在实现12个月戒烟率方面的有效性。这项研究还将研究裁剪深度对吸烟减少、变化阶段和基线特征(如性别、收入和教育)的影响。这项研究将与底特律的亨利·福特健康系统合作，招募参与者并实施基于网络的干预措施。随着基于网络的戒烟计划数量的增加，以及越来越多的人转向万维网寻求健康信息，这是一种高度互动的媒介，能够在任何时间以很低的成本接触到大量吸烟者，我们相信，该领域的目的是审查影响其在基于网络的戒烟干预措施中有效性的定制的特定方面。这类研究可能有助于理解为什么一些量身定制的干预措施会对戒烟产生积极影响，并为如何创建其他高效的量身定制干预措施提供洞察。

DESCRIPTION (provided by applicant): While the theoretical basis and effectiveness of print-based, tailored smoking cessation interventions have been examined in numerous studies, very little research has been conducted on the effectiveness of computer-tailored smoking cessation interventions delivered via the World Wide Web. Further, researchers in public health communications have little knowledge about the active ingredients of tailoring, the components that contribute to its effectiveness. This project proposes to examine the significance of a potential active ingredient: depth of tailoring. Depth of tailoring refers to the level of detail of tailoring and the interactions among theory-based tailoring constructs. A low-depth intervention may generate thousands of message combinations, while a high-depth program may generate billions of variations. High-depth interventions can create extensively tailored cessation messages, but do they result in better outcomes? Is it worth the time and energy to develop such comprehensive interventions? In a randomized 1x3 factorial design among 3,000 smokers, the study will compare the effectiveness of low versus medium-versus high-depth of tailoring in achieving 12-month smoking cessation rates. The study will also examine the impact of tailoring depth on smoking reduction, stage of change, and baseline characteristics such as gender, income, and education. The study will collaborate with Henry Ford Health System of Detroit to recruit participants and to implement the web-based interventions. As the number of web-based cessation programs increases and more people turn to the World Wide Web for health information, a highly interactive medium which is capable of reaching large numbers of smokers at any time and at little cost, we believe the field is posed to examine specific aspects of tailoring that influence its effectiveness in web-based smoking cessation interventions. Such research may provide understanding of why some tailored interventions positively influence cessation and insight into how to create other highly effective tailored interventions.
