Verification process of metric based usability evaluation model for chronic disease management mobile applications

Abstract

This paper explains the verification process of a proposed model for evaluating the usability of chronic disease management (CDM) applications. This research aims to symbolize main practices in evaluating the usability of the CDM application. Twelve (12) usability experts from academia, medical and mobile application development from around the globe participated in examining the model components. The experts completed a verification form and questionnaire that measured the model in terms of consistency, understandable, ease of use, tailorable, verifiable and overall impression. Furthermore, the proposed model has been modified based on the comments and suggestions received from experts. Similarly, the experts’ questionnaire result indicates that the proposed model is original, complete and acceptable. Therefore, this study will provide additional knowledge in both theory and practice towards model verification process, especially for usability evaluation of disease management applications.
