Whether early detection and treatment of prostate cancer (PCa) will reduce disease-related mortality remains uncertain. As a result, tools are needed to facilitate informed decision making. While there have been several decision aids (DAs) developed and tested, very few have included an exercise to help men clarify their values and preferences about PCa screening. Further, only one DA has utilized an interactive web-based format, which allows for an expansion and customization of the material. We describe the development of two DAs, a booklet and an interactive website, each with a values clarification component and designed for use in diverse settings.
We conducted two feasibility studies to assess men's (45-70 years) Internet access and their willingness to use a web- vs. a print-based tool. The booklet was adapted from two previous versions evaluated in randomized controlled trials (RCTs) and the website was created to closely match the content of the revised booklet. Usability testing was conducted to obtain feedback regarding draft versions of the materials. The tools were also reviewed by a plain language expert and the interdisciplinary research team. Feedback on the content and presentation led to iterative modifications of the tools.
The feasibility studies confirmed that the Internet was a viable medium, as the majority of men used a computer, had access to the Internet, and Internet use increased over time. Feedback from the usability testing on the length, presentation, and content of the materials was incorporated into the final versions of the booklet and website. Both the feasibility studies and the usability testing highlighted the need to address men's informed decision making regarding screening.
Informed decision making for PCa screening is crucial at present and may be important for some time, particularly if a definitive recommendation either for or against screening does not emerge from ongoing prostate cancer screening trials. We have detailed our efforts at developing print- and web-based DAs to assist men in determining how to best meet their PCa screening preferences. Following completion of our ongoing RCT designed to test these materials, our goal will be to develop a dissemination project for the more effective tool.

早期检测和治疗前列腺癌（PCa）是否会降低与疾病相关的死亡率仍不确定。因此，需要工具来帮助做出明智的决策。尽管已经开发和测试了几种决策辅助工具（DAs），但很少有工具包括帮助男性澄清他们对 PCa 筛查的价值观和偏好的练习。此外，只有一个 DA 使用了交互式网络格式，该格式允许扩展和定制材料。我们描述了两种 DA 的开发，一种是小册子，另一种是交互式网站，每种都有一个价值观澄清部分，并设计用于不同的环境。
我们进行了两项可行性研究，以评估男性（45-70 岁）的互联网接入情况及其使用网络工具与印刷工具的意愿。小册子改编自两项之前在随机对照试验（RCT）中评估过的版本，网站是为了与修订后的小册子的内容紧密匹配而创建的。对草案进行了可用性测试，以获得关于材料的反馈。这些工具还由一位简明语言专家和跨学科研究团队进行了审查。对内容和演示的反馈导致对工具进行了迭代修改。
可行性研究证实，互联网是一种可行的媒介，因为大多数男性使用计算机、可以访问互联网，并且互联网的使用随着时间的推移而增加。可用性测试对材料的长度、呈现方式和内容的反馈被纳入小册子和网站的最终版本。可行性研究和可用性测试都强调了需要解决男性关于筛查的知情决策。
目前，PCa 筛查的知情决策至关重要，并且在一段时间内可能很重要，特别是如果正在进行的前列腺癌筛查试验没有得出明确的筛查支持或反对建议。我们详细介绍了开发基于印刷和网络的 DAs 的努力，以帮助男性确定如何最好地满足他们的 PCa 筛查偏好。在完成我们正在进行的旨在测试这些材料的 RCT 之后，我们的目标将是为更有效的工具制定一个传播计划。
