Mobile Applications (apps) are commonly used in the health care settings to improve the quality of care, however prior to the release of the app it is vital to evaluate its usability. Therefore, the aim of this study is to adapt the mobile Health App Usability Questionnaire (MAUQ) and measure the usability of the Eye donor Aust App using the modified instrument (m-MAUQ).
The study was undertaken using a convenience sample of 94 patients and their carers attending three eye clinics and one outpatient department in a large hospital in Sydney Australia. The study was conducted in two phases. Phase 1 involved the adaptation of the MAUQ, and validity testing of the modified version. Phase 2 included the usability evaluation of the Eye donor Aust App using the modified MAUQ (m-MAUQ).
The m-MAUQ comprised of 15 items and the content validity of the instrument was considered satisfactory. Exploratory factor analysis supported a three-factor structure namely: ease of use and satisfaction (nine items), usefulness in obtaining information (three items), and system information arrangement (three items). The internal consistency for the subscales and the total scale was high with Cronbach's alpha values greater than 0.90. The usability score for the Eye donor Aust App was high (mean 5.99; SD 0.74). The construct validity was supported as there were no differences in usability scores among males and females. Older people found the app less useful for obtaining information about eye donation.
The results support the use of the m-MAUQ as a valid instrument to measure the usability of the Eye Donor Aust App. This instrument requires further testing in other groups of people. Usability testing of the Eye Donor Aust app demonstrated that the participants were satisfied with the content and functionality of the app stating that it was well organised, visually appealing and user friendly. This result could translate into more people using the app and thereby increasing their knowledge and attitude towards eye donation as well as registering to become a donor.
移动应用程序（apps）常用于改善医疗保健质量，但在发布应用程序之前，评估其可用性至关重要。因此，本研究旨在改编移动健康应用程序可用性问卷（MAUQ），并使用修改后的工具（m-MAUQ）来衡量 Eye donor Aust App 的可用性。
本研究采用便利样本，对 94 名患者及其护理人员进行了调查，这些患者和护理人员分别来自澳大利亚悉尼的三家眼科诊所和一家门诊病房。研究分两个阶段进行。第一阶段涉及 MAUQ 的改编和修改版本的有效性测试。第二阶段包括使用修改后的 MAUQ（m-MAUQ）对 Eye donor Aust App 的可用性进行评估。
m-MAUQ 由 15 个项目组成，该工具的内容有效性被认为是令人满意的。探索性因素分析支持了一个三因素结构，即：易用性和满意度（9 个项目）、获取信息的有用性（3 个项目）和系统信息安排（3 个项目）。子量表和总量表的内部一致性很高，克朗巴赫α值大于 0.90。Eye donor Aust App 的可用性得分较高（平均 5.99；SD 0.74）。结构有效性得到支持，因为男性和女性之间的可用性得分没有差异。老年人认为该应用程序对于获取有关眼捐赠的信息不太有用。
研究结果支持使用 m-MAUQ 作为一种有效的工具来衡量 Eye Donor Aust App 的可用性。该工具需要在其他人群中进一步测试。对 Eye Donor Aust App 的可用性测试表明，参与者对应用程序的内容和功能感到满意，他们表示该应用程序组织良好，具有吸引力，易于使用。这一结果可能会导致更多的人使用该应用程序，从而提高他们对眼捐赠的知识和态度，并注册成为捐赠者。
