Rigorous usability testing of e-learn-ing resources is an important prerequisite to their wide-spread use among clinicians. This study demonstrates the application of an evidence-based approach to usability testing of two stroke-related e-learning resources (StrokEngine).
14 stroke rehabilitation clinicians (occupational therapists and physiotherapists) from Ontario, Canada participated in a 1.5 h in-person testing session. Clinicians navigated StrokEngine in search of information to answer questions on stroke assessment/intervention. Their search patterns were observed and clinicians provided verbal/written feedback about StrokEngine. Content analysis was used to generate themes and categorize them under two broad categories: facilitators and barriers to use.
Five key facilitators and three key barriers to Strok-Engine use were identified and related to screen format, layout/organization, ease of navigation, quality of content, likelihood of using StrokEngine in the future, and system dysfunctions. All 14 clinicians were very or extremely satisfied with the layout/organization, quality and clinical relevance of the content, stating that they were likely to use StrokEngine in the future.
All identified barriers from this study were addressed with website modifications in order to maximize the usability and navigability of StrokEngine. This rigorous methodology for usability testing can be applied during the design process of any e-learning resource.
严格的电子学习资源可用性测试是其在临床医生中广泛使用的重要前提。本研究展示了一种循证方法在两项中风相关电子学习资源（StrokEngine）的可用性测试中的应用。
来自加拿大安大略省的 14 名中风康复临床医生（职业治疗师和物理治疗师）参加了一个 1.5 小时的现场测试会议。临床医生在 StrokEngine 中搜索信息以回答中风评估/干预方面的问题。观察他们的搜索模式，临床医生提供有关 StrokEngine 的口头/书面反馈。内容分析用于生成主题，并将其分为两类：使用的促进因素和障碍。
确定了五项使用 Strok-Engine 的关键促进因素和三项关键障碍，与屏幕格式、布局/组织、导航易用性、内容质量、未来使用 StrokEngine 的可能性以及系统功能障碍有关。所有 14 名临床医生都对布局/组织、内容的质量和临床相关性非常满意或极其满意，并表示他们将来可能会使用 StrokEngine。
为了最大限度地提高 StrokEngine 的可用性和可操作性，对网站进行了修改，以解决本研究中所有确定的障碍。这种严格的可用性测试方法可应用于任何电子学习资源的设计过程中。
