Literacy-scaffolded, web-based change of HIV risk intention

描述（由申请人提供）：这个SBIR申请假设一个定制的、互动的、识字的、基于网络的干预，基于一个经过验证的行为模型的改编，可以1)提高对艾滋病毒/艾滋病传播的理解，2)比一个具有类似内容的静态网站更能提高减少危险行为的意图。我们的具体目标是：1)开发一个以扫盲为基础的干预措施的试点版本，以促进对艾滋病毒/艾滋病传播的了解，并提高减少危险行为的意愿；2)评估对艾滋病毒感染者或有感染风险的人实施干预的可行性，以提高对艾滋病毒/艾滋病传播的认识，提高减少危险行为的意愿，并获得干预的反馈；3)开发我们的第二阶段应用程序。在保证匿名和解释干预的潜在价值的情况下，我们将从艾滋病毒诊所和检测机构招募18至35岁的参与者。来自目标受众的审查小组将协助内容开发并帮助评估第一阶段试点。在网站前的调查中，我们将评估参与者对艾滋病毒/艾滋病（特别是传播）的了解，对个人感染或传播艾滋病毒的易感性的感知，报告的增加感染或传播艾滋病毒风险的行为，对同伴群体规范的感知，改变风险行为的障碍和利益的平衡，以及自我效能感。通过将这些输入与针对艾滋病毒感染者和非艾滋病毒感染者的离散方法相结合，并以健康信念模型的改编为指导，我们将通过提供以三个阅读能力水平编写的个性化内容来定制每个参与者所看到的内容。与浏览传统网站的对照组相比，这个个性化的网站有望1)激励和吸引参与者，2)帮助所有人，包括那些识字率低的人，更好地了解他们需要和想要了解的艾滋病毒/艾滋病，3)提高减少危险行为的意愿，4)提高高危参与者的艾滋病毒筛查率，5)对同伴群体规范的感知产生积极影响。我们预计最终产品的定制版本将具有商业应用，从而通过许可向医生、诊所和医疗保健支持团体广泛传播；企业;大学、学院、社区学院、预科学校和高中；和个人。鉴于每年仍有40 000人感染艾滋病毒，一种减少感染/传播艾滋病毒风险行为的有效手段将具有巨大的公共卫生价值，这种行为可以以低成本广泛传播。

DESCRIPTION (provided by applicant): This SBIR application hypothesizes that a tailored, interactive, literacy-scaffolded, web-based intervention that is based on an adaptation of a validated, behavioral model can 1) improve understanding of transmission of HIV/AIDS and 2) improve intent to reduce risky behavior more than a static website with similar content. Our specific aims are to: 1) develop a pilot version of a literacy-scaffolded intervention to promote understanding of HIV/AIDS transmission and improve intent to reduce risky behavior; 2) evaluate the feasibility of using the intervention for both those with HIV or at risk for acquiring it to improve understanding of HIV/AIDS transmission, improve intent to reduce risky behavior, and obtain feedback on the intervention; and 3) develop our Phase II application. With assurances of anonymity and explanation of potential value of the intervention, we will recruit participants 18 to 35 years old from HIV clinics and testing facilities. A review team from the target audience will assist with content development and help evaluate the Phase I pilot. In a pre-website survey, we will assess participants' knowledge about HIV/AIDS (especially transmission), perception of personal susceptibility of acquiring or spreading HIV, reported behaviors that increase their risk of acquiring or spreading HIV, perception of peer group norms, balance of barriers to and benefits of changing their risk behavior, and feelings of self-efficacy. By combining this input with discrete approaches for those with and without HIV, and guided by an adaptation of the Health Belief Model, we will tailor what each participant sees by providing personalized, content written at 3 levels of reading ability. In comparison with controls viewing a conventional website, this individualized website is expected to 1) motivate and engage participants, 2) help all, including those with low literacy, to understand better what they need and want to know about HIV/AIDS, 3) improve intention to reduce risky behavior, 4) increase rates of HIV screening among at-risk participants, and 5) have a positive effect on perception of peer group norms. We anticipate that customized versions of the resulting product will have commercial applications leading to widespread dissemination via license to physicians, clinics, and health care support groups; corporations; universities, colleges, community colleges, preparatory schools, and high schools; and individuals. With 40,000 people/yr continuing to be infected with HIV, an effective means to reduce risk behaviors for contracting/transmitting HIV that could be disseminated widely at low cost would have great public health value.
