Usability of mobile applications: A Concept Analysis to be used in health promotion (Preprint)
BACKGROUND Following the rise of health awareness in modern societies, health promotion has attracted progressively more attention in both academia and industry. This, along with the evolution of information and communication technologies, has resulted in the development of several mobile applications used in health promotion. Unfortunately, users of the applications have not achieved their goals, since many applications have not provided a smooth user experience. OBJECTIVE To clearly identify the defining attributes of mobile app usability in the context of health promotion in order to guide the design of apps which provide smooth user experience. METHODS It is thus first necessary to conduct an exploration into app usability, for which this study applies the concept analysis method by Walker and Avant, which includes: (1) identifying the use of the concept, (2) determining the defining attributes, (3) constructing a model case, (4) constructing model, contrary, borderline, and related cases, (5) identifying antecedents and consequences, and (6) defining empirical referents. RESULTS We then derive a unified definition of usability from the healthcare perspective—that the defining attributes of "usability of mobile application" are: efficiency, user satisfaction, and learnability. CONCLUSIONS It is concluded that mobile applications with these attributes could achieve their designed goals and reach maximal efficacy, since users would continue using the app on a regular basis, and would recommend it to others.
