Mild traumatic brain injury (mTBI) is a significant cause of morbidity for adolescents. Currently, there is a lack of evidence-based interventions to address common sequelae of mTBI. To address this gap, we designed a program to promote recovery for adolescents following mTBI. Preliminary testing of the Self-Monitoring Activity Regulation and Relaxation Treatment (SMART) program demonstrated good usability but indicated a need for modifications to the program. The SMART application was redesigned with the addition of more interactive and gamified components. Content was also reframed to specifically target and engage adolescents with mTBI. We describe the usability evaluation of the updated SMART application. Children aged 11–18 years diagnosed with mTBI who were 1 to 6 months post mTBI were recruited to participate in a 1-–2-h usability session in which they thought aloud and responded to targeted usability-related questions during their interaction with SMART. After completing the session, participants rated their usability experience using the System Usability Scale (SUS) and rated the overall user-friendliness of the program. Participants’ responses during the session were qualitatively coded and analyzed. Six adolescents participated in a usability session (average age = 13.7 years). On the SUS, participants rated the program as highly usable ( M = 85.6, SD = 3.24). They also had overwhelmingly positive feedback regarding the content, design, and structure of the program. Overall, findings suggest that the redesigned SMART program was usable, acceptable, and relevant to adolescents with mTBI. Based on adolescents’ feedback, additional modifications were made before the program undergoes efficacy testing.

针对轻度创伤性脑损伤青少年的自助式移动健康应用程序的用户体验（重新）设计和评估


轻度创伤性脑损伤（mTBI）是青少年发病的一个重要原因。目前，缺乏基于证据的干预措施来解决 mTBI 的常见后遗症。为了弥补这一差距，我们设计了一项促进 mTBI 青少年康复的计划。自我监控活动调节和放松治疗（SMART）程序的初步测试显示出良好的可用性，但表明需要对该程序进行修改。 SMART 应用程序经过重新设计，添加了更多交互性和游戏化组件。内容也经过重新设计，专门针对并吸引患有 mTBI 的青少年。我们描述了更新后的 SMART 应用程序的可用性评估。招募 mTBI 后 1 至 6 个月诊断为 mTBI 的 11-18 岁儿童参加为期 1-2 小时的可用性会议，他们在与 SMART 互动的过程中大声思考并回答有针对性的可用性相关问题。完成会议后，参与者使用系统可用性量表（SUS）对他们的可用性体验进行评分，并对程序的整体用户友好性进行评分。参与者在会议期间的反应被定性编码和分析。六名青少年参加了可用性会议（平均年龄 = 13.7 岁）。在 SUS 上，参与者将该程序评为高度可用（M = 85.6，SD = 3.24）。他们还对项目的内容、设计和结构给予了压倒性的积极反馈。总体而言，研究结果表明，重新设计的 SMART 计划对于患有 mTBI 的青少年来说是可用的、可接受的且相关的。根据青少年的反馈，在该计划进行功效测试之前进行了额外的修改。
