Self-care behaviors are commonly prescribed to manage both cardiovascular disease and hypertension to reduce modifiable risk factors and improve quality of life. Nevertheless, long-term adherence to self-care recommendations for cardiac patients has been problematic. In cardiac patients, moderated online forums have been found to be particularly useful in supporting maintenance of heart-healthy diet and fewer hospital visits. As such, we developed the e-Forum, a Web-based moderated forum designed to promote continued user engagement and long-term self-care adherence.
The objective of this study was to assess the usability of the user interface for the newly designed e-Forum. In addition to overall user satisfaction, we obtained feedback from our target users on the key features of this newly developed interface.
An iterative design tested the usability of the e-Forum. On the basis of the user feedback, adjustments were made to the design of our e-Forum, and these changes were then tested in the succeeding group. Participants were recruited from the Heart Function Clinic at the Peter Munk Cardiac Center, University Health Network. After consenting to participate in our study, patients were asked to complete a set of goal-oriented tasks and a feedback interview for the e-Forum. A content analysis of the transcripts from the set of goal-oriented tasks and feedback interviews identified several themes, including general feedback and comments regarding 3 key areas of the e-Forum: layout, navigation, and content.
Overall, 13 cardiac patients (aged 32-81 years) participated in 3 rounds of testing. Participants across all 3 rounds were highly satisfied with our e-Forum and indicated that they would find such a forum useful in managing their health. Expressions of overall satisfaction with the e-Forum and positive comments regarding layout increased between the initial and the final round. As improvements were made to the e-Forum based on participant feedback, potential barriers, negative comments related to the content, and the number of navigation errors decreased between rounds 1 and 3.
We found evidence to support the usability of the user interface for our e-Forum. These results indicate that the e-Forum will likely be a successful tool to support an online community of cardiac patients in their efforts to sustain long-term lifestyle behavior change.
自我护理行为通常被推荐用于管理心血管疾病和高血压，以减少可改变的风险因素并提高生活质量。然而，心脏病患者长期坚持自我护理建议一直存在问题。在心脏病患者中，发现有适度管理的在线论坛对维持心脏健康饮食和减少住院次数特别有用。因此，我们开发了电子论坛，这是一个基于网络的、有适度管理的论坛，旨在促进用户持续参与并长期坚持自我护理。
本研究的目的是评估新设计的电子论坛用户界面的可用性。除了总体用户满意度外，我们还从目标用户那里获得了关于这个新开发界面关键特性的反馈。
采用迭代设计测试电子论坛的可用性。根据用户反馈，对电子论坛的设计进行调整，然后在后续组中对这些更改进行测试。参与者从大学健康网络彼得·芒克心脏中心的心脏功能诊所招募。在同意参与我们的研究后，患者被要求完成一组面向目标的任务以及对电子论坛的反馈访谈。对面向目标的任务和反馈访谈记录的内容分析确定了几个主题，包括关于电子论坛三个关键领域的一般反馈和评论：布局、导航和内容。
总体而言，13名心脏病患者（年龄在32至81岁之间）参与了三轮测试。所有三轮的参与者对我们的电子论坛都非常满意，并表示他们会发现这样一个论坛对管理他们的健康很有用。从第一轮到最后一轮，对电子论坛的总体满意度表达以及对布局的积极评论有所增加。随着根据参与者反馈对电子论坛进行改进，潜在障碍、与内容相关的负面评论以及导航错误的数量在第1轮和第3轮之间有所减少。
我们发现有证据支持我们电子论坛用户界面的可用性。这些结果表明，电子论坛可能会成为一个成功的工具，以支持心脏病患者在线社区努力维持长期生活方式行为改变。
