To verify the effectiveness, efficiency, and satisfaction in the usability test of the tinnitus assessment application.
This is a descriptive usability test study that assessed the satisfaction, effectiveness, and efficiency of the application. The test was carried out virtually via Google Forms. First, the participants received instructions on how to access and use Avazum, through texts and illustrative images. Afterward, the users used the application, observing its functions and usability. Next, the participants answered the usability questionnaire. Statistical analysis was performed using the Statistical Package for the Social Sciences, version 21.0, to perform descriptive analysis such as frequency, percentages of data in the System Usability Questionnaire (SUS), and analysis in the Net Promoter Score (NPS).
Thus, the overall mean SUS score was consistent with satisfactory usability, which implies that the application does not present serious usability problems. Also, the overall NPS percentage indicated very good user satisfaction, with a good percentage of promoting users. As far as effectiveness is concerned, it was found that Avazum reached its goals, besides being efficient, as it uses clear language and is comfortably used.
Avazum obtained very good satisfaction from users, in addition to achieving its goals. It proved to be effective, has clear language, and is comfortably used, adducing efficiency in the multidisciplinary evaluation of tinnitus.
验证耳鸣评估应用程序可用性测试中的有效性、效率和满意度。
这是一项描述性可用性测试研究，评估了该应用程序的满意度、有效性和效率。测试通过谷歌表单以虚拟方式进行。首先，参与者通过文本和说明性图像接收有关如何访问和使用Avazum的说明。之后，用户使用该应用程序，观察其功能和可用性。接下来，参与者回答可用性问卷。使用社会科学统计软件包21.0进行统计分析，以进行描述性分析，如频率、系统可用性问卷（SUS）中数据的百分比，以及净促进者得分（NPS）分析。
因此，SUS的总体平均得分与令人满意的可用性一致，这意味着该应用程序不存在严重的可用性问题。此外，NPS的总体百分比表明用户满意度非常高，有相当比例的促进用户。就有效性而言，发现Avazum除了高效之外，还达到了其目标，因为它使用清晰的语言且使用起来很舒适。
Avazum除了实现其目标外，还获得了用户的高度满意度。它被证明是有效的，语言清晰，使用舒适，在耳鸣的多学科评估中提高了效率。
