The Malay Version of the mHealth App Usability Questionnaire (M-MAUQ): Translation, adaptation and validation study
ABSTRACT
Background:
mHealth apps play an important role in education delivery, providing advice on treatment and monitoring patients’ health. Good usability of mHealth apps is essential to achieve its objective efficiently. To date, there are questionnaires available to assess the general system usability scale (SUS). However, for mHealth apps, it is crucial to have a specific tool which precisely assess the usability of the aforementioned apps. Hence, the mHealth App Usability Questionnaire (MAUQ) was developed for this purpose.
Objective:
The aim of this study was to translate and validate the English version of MAUQ (standalone for patients) into a Malay version of MAUQ (M-MAUQ) for the future mHealth app research and usage in Malaysia.
Methods:
Forward and backward translation and harmonization of M-MAUQ were conducted by Malay native speakers, who also spoke English as their second language. Next, content and face validation were conducted among ten experts and ten target users, respectively. Kappa was used to determine inter-rater agreement among the raters. The reliability was also conducted among 51 young adult and healthy mobile phone users.
Results:
The content validity index for relevancy and clarity of M-MAUQ were determined to be 0.983 and 0.944, respectively, that indicates good relevancy and clarity. The face validity index for understandability was 0.961, which indicates that users understand the M-MAUQ. The Cronbach alpha for 18-items was 0.946, also indicated a good reliability in assessing the usability of the mHealth app.
Conclusions:
The Malay version of the mHealth App Usability Questionnaire fulfilled the validation criteria as it reveals good reliability and validity similar to the original version.
