mHealth App Usability Questionnaire Development

To create the desired questionnaire, we reviewed a large number of published papers about mHealth apps and then created an mHealth app usability questionnaire (MAUQ) based on the questionnaires used in these published studies, taking into consideration the uniqueness of mobile devices and mHealth apps. We then used this newly developed questionnaire in a usability study on two mHealth apps. A psychometric analysis was performed to evaluate the reliability of the MAUQ as well as the correlation between the results from the MAUQ and those from the SUS and PSSUQ.
