Introduction

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).

Methods

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).

Results

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.

Conclusions

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.

适应 MAUQ 和基于手机的系统的可用性评估以促进眼睛捐赠

介绍

移动应用程序（应用程序）通常在医疗保健环境中用于提高护理质量，但是在发布应用程序之前，评估其可用性至关重要。因此，本研究的目的是调整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）测量眼睛捐赠者 Aust 应用程序的可用性。

方法

这项研究是使用澳大利亚悉尼一家大型医院三个眼科诊所和一个门诊部的 94 名患者及其护理人员的方便样本进行的。该研究分两个阶段进行。第一阶段涉及 MAUQ 的调整以及修改版本的有效性测试。第 2 阶段包括使用修改后的 MAUQ (m-MAUQ) 对眼睛捐赠者 Aust 应用程序进行可用性评估。

结果

m-MAUQ 由 15 个项目组成，该工具的内容效度被认为是令人满意的。探索性因素分析支持三因素结构，即：易用性和满意度（九项）、获取信息的有用性（三项）和系统信息安排（三项）。各分量表和总量表的内部一致性较高，Cronbach's alpha 值大于 0.90。眼睛捐赠者 Aust 应用程序的可用性得分很高（平均值 5.99；SD 0.74）。结构效度得到了支持，因为男性和女性的可用性得分没有差异。老年人发现该应用程序对于获取有关眼睛捐赠的信息不太有用。
