BACKGROUND
The Website Developmental Model for the Healthcare Consumer (WDMHC) is an extensive and successfully evaluated framework that incorporates user-centered design principles. However, due to its extensiveness its application is limited. In the current study we apply a subset of the WDMHC framework in a case study concerning the development and evaluation of a website aimed at childhood cancer survivors (CCS).
OBJECTIVE
To assess whether the implementation of a limited subset of the WDMHC-framework is sufficient to deliver a high-quality website with few usability problems, aimed at a specific patient population.
METHODS
The website was developed using a six-step approach divided into three phases derived from the WDMHC: 1) information needs analysis, mock-up creation and focus group discussion; 2) website prototype development; and 3) heuristic evaluation (HE) and think aloud analysis (TA). The HE was performed by three double experts (knowledgeable both in usability engineering and childhood cancer survivorship), who assessed the site using the Nielsen heuristics. Eight end-users were invited to complete three scenarios covering all functionality of the website by TA.
RESULTS
The HE and TA were performed concurrently on the website prototype. The HE resulted in 29 unique usability issues; the end-users performing the TA encountered eleven unique problems. Four issues specifically revealed by HE concerned cosmetic design flaws, whereas two problems revealed by TA were related to website content.
CONCLUSION
Based on the subset of the WDMHC framework we were able to deliver a website that closely matched the expectancy of the end-users and resulted in relatively few usability problems during end-user testing. With the successful application of this subset of the WDMHC, we provide developers with a clear and easily applicable framework for the development of healthcare websites with high usability aimed at specific medical populations.
背景
医疗消费者网站开发模型（WDMHC）是一个广泛且经过成功评估的框架，它融入了以用户为中心的设计原则。然而，由于其广泛性，其应用受到限制。在本研究中，我们在一个关于针对儿童癌症幸存者（CCS）的网站开发与评估的案例研究中应用了WDMHC框架的一个子集。
目的
评估实施WDMHC框架的一个有限子集是否足以提供一个针对特定患者群体且几乎没有可用性问题的高质量网站。
方法
该网站采用六步法开发，分为源自WDMHC的三个阶段：1）信息需求分析、原型创建和焦点小组讨论；2）网站原型开发；3）启发式评估（HE）和出声思考分析（TA）。HE由三位双专家（在可用性工程和儿童癌症幸存者领域均有知识）进行，他们使用尼尔森启发式方法评估该网站。邀请八位最终用户通过TA完成涵盖网站所有功能的三个场景。
结果
HE和TA在网站原型上同时进行。HE发现了29个独特的可用性问题；进行TA的最终用户遇到了11个独特问题。HE特别揭示的四个问题涉及外观设计缺陷，而TA揭示的两个问题与网站内容有关。
结论
基于WDMHC框架的这个子集，我们能够提供一个与最终用户期望紧密匹配且在最终用户测试期间产生相对较少可用性问题的网站。通过成功应用WDMHC的这个子集，我们为开发者提供了一个清晰且易于应用的框架，用于开发针对特定医疗群体且具有高可用性的医疗网站。
