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-hour usability session in which they thought aloud and responded to targeted usability-related questions during their interaction with the SMART program. 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.
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应对mTBI的常见后遗症。为了填补这一空白，我们设计了一个促进mTBI后青少年康复的项目。自我监测活动调节与放松治疗（SMART）项目的初步测试显示出良好的可用性，但表明该项目需要修改。SMART应用程序进行了重新设计，增加了更多互动和游戏化的组件。内容也进行了重新构建，以专门针对mTBI青少年并吸引他们参与。我们描述了更新后的SMART应用程序的可用性评估。招募了11至18岁、被诊断为mTBI且处于mTBI后1至6个月的儿童，参加一个1至2小时的可用性测试环节，在与SMART项目互动过程中，他们边思考边回答与可用性相关的针对性问题。测试环节结束后，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，并对该项目的整体用户友好性进行评分。对参与者在测试环节中的回答进行定性编码和分析。六名青少年参加了可用性测试环节（平均年龄 = 13.7岁）。在SUS上，参与者将该项目评为高度可用（M = 85.6，SD = 3.24）。他们对该项目的内容、设计和结构也给出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项目对mTBI青少年是可用的、可接受的且相关的。根据青少年的反馈，在该项目进行疗效测试之前又做了进一步修改。
