To assess technical usability of the BigO app and clinical portal among diverse participants and explore the overall user experiences of both.
Methods included technical usability testing by measuring the relative user efficiency score (RUS) for the app and measuring Relative User Efficiency (RUE) using the 'think aloud' method with the clinical portal. Qualitative approaches involved focus groups with adolescent app users and semi-structured one-to-one interviews with clinician participants. Thematic analysis was applied to analyze qualitative data.
Clinical participants consisted of adolescents seeking treatment for severe obesity and were invited via telephone/face to face to attend technical usability testing and a focus group. Healthcare professionals (HCPs) and researchers using the BigO clinical portal interface were invited to participate in usability testing and semi-structured interviews.
From 14 families invited to attend, seven consented to join the study and four adolescents (mean age=13.8 (SD 0.8) years) participated. Additionally, six HCPs and one pediatric obesity researcher took part. RUS for adolescents indicated that the tasks required of them via myBigO app were feasible, and technically efficient. No user-related errors were observed during tasks. Technical barriers reported by adolescents included notifications of battery optimization, misunderstanding image annotation language, and compatibility challenges with certain phone models. RUS for the HCPs and researcher indicated that basic technical skills are a potential barrier for clinical portal use and qualitative findings revealed that clinical users wanted a logging option for monitoring goals and providing feedback on the portal.
Our study provided valuable formative findings from clinical end-users in Ireland indicating that adolescents being treated for obesity rated myBigO app as usable, acceptable and that it may assist other key stakeholders to understand food marketing and to monitor dietary and physical activity behaviors. Several key suggestions for future iterations of the clinical portal were provided to enhance its value in pediatric obesity treatment.
评估BigO应用程序和临床门户在不同参与者中的技术可用性，并探索两者的整体用户体验。
方法包括通过测量应用程序的相对用户效率得分（RUS）进行技术可用性测试，以及使用“出声思考”方法对临床门户测量相对用户效率（RUE）。定性方法包括与青少年应用程序用户进行焦点小组讨论，以及与临床参与者进行半结构化一对一访谈。应用主题分析来分析定性数据。
临床参与者包括寻求治疗严重肥胖症的青少年，通过电话/面对面邀请他们参加技术可用性测试和焦点小组讨论。邀请使用BigO临床门户界面的医疗保健专业人员（HCPs）和研究人员参加可用性测试和半结构化访谈。
在受邀参加的14个家庭中，7个同意加入研究，4名青少年（平均年龄 = 13.8（标准差0.8）岁）参与。此外，6名HCPs和1名儿科肥胖症研究人员也参与其中。青少年的RUS表明，通过myBigO应用程序要求他们完成的任务是可行的，并且在技术上是高效的。在任务过程中未观察到与用户相关的错误。青少年报告的技术障碍包括电池优化通知、对图像注释语言的误解以及与某些手机型号的兼容性挑战。HCPs和研究人员的RUS表明，基本技术技能是临床门户使用的潜在障碍，定性研究结果显示，临床用户希望有一个记录选项来监测目标并在门户上提供反馈。
我们的研究提供了来自爱尔兰临床最终用户的宝贵形成性研究结果，表明接受肥胖症治疗的青少年认为myBigO应用程序可用、可接受，并且它可能有助于其他关键利益相关者了解食品营销并监测饮食和身体活动行为。为临床门户的未来迭代提供了几个关键建议，以提高其在儿科肥胖症治疗中的价值。
