The aim of this study was to evaluate the usability of the e-Ouch electronic chronic pain diary in adolescents with juvenile idiopathic arthritis.
A qualitative usability testing approach with semistructured, audiotaped interviews with two iterative cycles was used. A purposive sample of 10 adolescents per cycle was drawn from a rheumatology clinic in a university-affiliated pediatric tertiary care center. Participants were provided with a brief demonstration of the diary and then asked to use the diary "thinking aloud" to record the pain they experienced: (1) when they woke up that morning, (2) during that afternoon, and (3) from the previous evening. Adolescents were then asked a series of open-ended questions addressing ease of use of the diary. Qualitative thematic analysis was used to generate categories and emerging themes from interview data.
All of the adolescents stated the e-Ouch diary was very easy to learn, use, and understand and was satisfying to complete. Participants took less than 9 minutes to complete all three of the diary entries with minimal errors. The usability evaluation revealed aspects of the interface that were suboptimal (eg, VAS slider) and impeded the performance of certain tasks. Adolescents generated ideas on how the diary interface could be improved.
A multifaceted usability approach provided important insight regarding the use of technology by adolescents with arthritis and, more specifically, for understanding how adolescents can more effectively use an electronic chronic pain diary.
本研究旨在评估e - Ouch电子慢性疼痛日记在青少年特发性关节炎患者中的可用性。
采用定性可用性测试方法，进行两轮半结构化的录音访谈。每轮从一所大学附属儿科三级护理中心的风湿病诊所选取10名青少年作为有目的的样本。向参与者简要演示了该日记，然后要求他们“边想边说”使用日记记录他们经历的疼痛：（1）当天早上醒来时，（2）当天下午，以及（3）前一晚。之后，向青少年询问了一系列关于日记易用性的开放式问题。采用定性主题分析从访谈数据中生成类别和新出现的主题。
所有青少年均表示e - Ouch日记非常易于学习、使用和理解，完成起来也令人满意。参与者完成所有三项日记记录用时不到9分钟，且错误极少。可用性评估揭示了界面中存在的一些不够理想的方面（如视觉模拟评分滑块），这些方面妨碍了某些任务的执行。青少年提出了关于如何改进日记界面的想法。
多方面的可用性方法为了解关节炎青少年对技术的使用情况，更具体地说，为理解青少年如何能更有效地使用电子慢性疼痛日记提供了重要见解。
