Computer-based systems (CBS) can provide information to help individuals analyze their health care needs and make decisions about management of health problems. This article discusses the development of a CBS that delivers an individualized educational intervention for continence health promotion. System development included cycles of prototype design, testing, analysis, and redesign. Knowledge acquisition, representation methods, and design decisions are discussed. Participants completed 4 rounds of usability testing and a pilot test, which resulted in enhancements to both the CBS and the expert system feature that produced individualized feedback. This iterative design process involved users throughout system development. User involvement resulted in a tutorial to explain navigation and other features of the CBS, graphics to enhance the written message, and clarification of continence-related content. The procedures resulted in an informative, usable product; they can be used to develop systems that provide information about symptom self-management for other health conditions.
基于计算机的系统（CBS）可以提供信息，帮助个人分析他们的医疗保健需求，并就健康问题的管理做出决策。本文讨论了一种CBS的开发，该系统提供针对尿失禁健康促进的个性化教育干预。系统开发包括原型设计、测试、分析和重新设计的循环。讨论了知识获取、表示方法和设计决策。参与者完成了4轮可用性测试和一次试点测试，这导致了CBS和产生个性化反馈的专家系统功能的改进。这种迭代设计过程在整个系统开发过程中都有用户参与。用户的参与产生了一个用于解释CBS导航和其他功能的教程、增强书面信息的图形以及对尿失禁相关内容的澄清。这些程序产生了一个信息丰富、可用的产品；它们可用于开发提供其他健康状况症状自我管理信息的系统。
