移动应用程序是一种编程系统，旨在供目标用户在移动设备上使用。这样一个系统的可用性不仅是指产品在多大程度上可以被用来完成它所设计的任务，还包括它的有效性和效率，以及用户的满意度。系统可用性量表是最常用的用于评估系统可用性的问卷之一。最初的10项系统可用性量表是用英语开发的，因此需要改编成当地语言来评估用其他语言开发的移动应用程序的可用性。本研究的目的是将英语系统可用性量表问卷翻译成马来语，马来语是马来西亚的主要语言。翻译版本的开发将允许用马来语评估移动应用程序的可用性。问卷的前向和后向翻译是由以英语为第二语言的马来语母语人士进行的。最终版本是经过和解和跨文化改编而成的。马来系统可用性量表（Malay System Usability Scale）调查问卷的内容经过了10位移动应用开发专家的验证。通过对10名手机用户进行面部效度测试，再对54名手机用户进行信度测试，进一步验证问卷的有效性。确定的内容效度指数为0.91，表明用于评估移动应用可用性的10个项目的相关性较好。面部效度指数的计算结果为0.94，表明该问卷易于被用户理解。信度检验显示Cronbach alpha值为。85 （95% CI 0.79-0.91）表明翻译后的系统可用性量表问卷是评估移动应用程序可用性的可靠工具。马来系统可用性量表问卷是评估马来西亚移动应用程序可用性的有效可靠工具。
A mobile app is a programmed system designed to be used by a target user on a mobile device. The usability of such a system refers not only to the extent to which product can be used to achieve the task that it was designed for, but also its effectiveness and efficiency, as well as user satisfaction. The System Usability Scale is one of the most commonly used questionnaires used to assess the usability of a system. The original 10-item version of System Usability Scale was developed in English and thus needs to be adapted into local languages to assess the usability of a mobile apps developed in other languages. The aim of this study is to translate and validate (with cross-cultural adaptation) the English System Usability Scale questionnaire into Malay, the main language spoken in Malaysia. The development of a translated version will allow the usability of mobile apps to be assessed in Malay. Forward and backward translation of the questionnaire was conducted by groups of Malay native speakers who spoke English as their second language. The final version was obtained after reconciliation and cross-cultural adaptation. The content of the Malay System Usability Scale questionnaire for mobile apps was validated by 10 experts in mobile app development. The efficacy of the questionnaire was further probed by testing the face validity on 10 mobile phone users, followed by reliability testing involving 54 mobile phone users. The content validity index was determined to be 0.91, indicating good relevancy of the 10 items used to assess the usability of a mobile app. Calculation of the face validity index resulted in a value of 0.94, therefore indicating that the questionnaire was easily understood by the users. Reliability testing showed a Cronbach alpha value of .85 (95% CI 0.79-0.91) indicating that the translated System Usability Scale questionnaire is a reliable tool for the assessment of usability of a mobile app. The Malay System Usability Scale questionnaire is a valid and reliable tool to assess the usability of mobile app in Malaysia.
