The symptom reporting app was co-designed with school-age children with cancer, their parents, and clinicians. Preliminary studies demonstrated its feasibility and acceptability; however, children and parents identified the need for additional refinements.
Guided by the Technology Acceptance Model and principles of user-centered design, this study supported refinements to the user interface and evaluation of its usability. As the programming team completed builds of the app, school-age children with cancer and their parents participated in cognitive walkthrough usability evaluations and qualitative interviews. Usability logs documented the completion of key tasks related to reporting pain and review of child-reported data. Parents completed the Technology Acceptance Model Perceived Usefulness Scale (TAM-PUS). Interview responses were analyzed using qualitative content analysis.
Fourteen children (median age 8.5 years; range 6-12) and 14 parents (median age 38.5 years; range 34-49) participated in one of three usability evaluation cycles. After the third cycle, children and parents navigated the app and completed key tasks independently. Median TAM-PUS scores were 6 (range 6-8), indicating high perceived usefulness. Qualitative analyses indicated that children regarded the app as easy and fun to use. Parents emphasized the app's developmental relevance for their child and for themselves as the child's caregiver.
This study demonstrates the perceived usefulness and perceived ease of use of the revised app. Optimizing the usability of the app with attention to the user needs of children and parents positions the app for wider-scale clinical implementation.
症状报告应用程序是与患癌学龄儿童、他们的父母以及临床医生共同设计的。初步研究证明了其可行性和可接受性；然而，儿童和父母认为需要进一步完善。
在技术接受模型和以用户为中心的设计原则的指导下，本研究支持对用户界面进行优化并评估其可用性。随着编程团队完成应用程序的构建，患癌学龄儿童及其父母参与了认知走查可用性评估和定性访谈。可用性日志记录了与报告疼痛和查看儿童报告数据相关的关键任务的完成情况。父母完成了技术接受模型感知有用性量表（TAM-PUS）。使用定性内容分析法对访谈回复进行分析。
14名儿童（中位年龄8.5岁；范围6-12岁）和14名父母（中位年龄38.5岁；范围34-49岁）参与了三个可用性评估周期中的一个。在第三个周期之后，儿童和父母能够独立操作应用程序并完成关键任务。TAM-PUS得分中位数为6（范围6-8），表明感知有用性较高。定性分析表明，儿童认为该应用程序使用起来轻松有趣。父母强调该应用程序对他们的孩子以及作为孩子照顾者的自己具有发展意义。
本研究证明了修订后的应用程序的感知有用性和易用性。关注儿童和父母的用户需求来优化应用程序的可用性，为该应用程序更广泛的临床实施奠定了基础。
