Development and Validation of a Mobile App for Burn Healing Care based on Interactive Design

BACKGROUND After a mobile health (mHealth) app is created, an important step is to evaluate the usability of the app before it is released to the public. There are multiple ways of conducting a usability study, one of which is collecting target users’ feedback with a usability questionnaire. Different groups have used different questionnaires for mHealth app usability evaluation: The commonly used questionnaires are the System Usability Scale (SUS) and Post-Study System Usability Questionnaire (PSSUQ). However, the SUS and PSSUQ were not designed to evaluate the usability of mHealth apps. Self-written questionnaires are also commonly used for evaluation of mHealth app usability but they have not been validated. OBJECTIVE The goal of this project was to develop and validate a new mHealth app usability questionnaire. METHODS An mHealth app usability questionnaire (MAUQ) was designed by the research team based on a number of existing questionnaires used in previous mobile app usability studies, especially the well-validated questionnaires. MAUQ, SUS, and PSSUQ were then used to evaluate the usability of two mHealth apps: an interactive mHealth app and a standalone mHealth app. The reliability and validity of the new questionnaire were evaluated. The correlation coefficients among MAUQ, SUS, and PSSUQ were calculated. RESULTS In this study, 128 study participants provided responses to the questionnaire statements. Psychometric analysis indicated that the MAUQ has three subscales and their internal consistency reliability is high. The relevant subscales correlated well with the subscales of the PSSUQ. The overall scale also strongly correlated with the PSSUQ and SUS. Four versions of the MAUQ were created in relation to the type of app (interactive or standalone) and target user of the app (patient or provider). A website has been created to make it convenient for mHealth app developers to use this new questionnaire in order to assess the usability of their mHealth apps. CONCLUSIONS The newly created mHealth app usability questionnaire—MAUQ—has the reliability and validity required to assess mHealth app usability.

Background The System Usability Scale (SUS) is a common metric used to assess the usability of a system, and it was initially developed in English. The implementation of electronic systems for clinical counseling (eHealth and mobile health) is increasing worldwide. Therefore, tools are needed to evaluate these applications in the languages and regional contexts in which the electronic tools are developed. Objective This study aims to translate, culturally adapt, and validate the original English version of the SUS into a Spanish version. Methods The translation process included forward and backward translation. Forward translations were made by 2 native Spanish speakers who spoke English as their second language, and a backward translation was made by a native English speaker. The Spanish SUS questionnaire was validated by 10 experts in mobile app development. The face validity of the questionnaire was tested with 10 mobile phone users, and the reliability testing was conducted among 88 electronic application users. Results The content validity index of the new Spanish SUS was good, as indicated by a rating of 0.92 for the relevance of the items. The questionnaire was easy to understand, based on a face validity index of 0.94. The Cronbach α was .812 (95% CI 0.748-0.866; P<.001). Conclusions The new Spanish SUS questionnaire is a valid and reliable tool to assess the usability of electronic tools among Spanish-speaking users.

In this paper, we try to find the relationship between design factors and social presence in mobile application stores. Social presence in mobile app stores consists of intimacy, social atmosphere and interpersonal interaction and design factors including structure design, content design, visual design and interactive design. We used semantic differential scale method to test the effects of design factors on users’ social presence. The result shows that the interactive design has significant effects on social atmosphere. Structure design has significant effects on interpersonal interaction. The result shows that design factors have significant effects on social presence. Obviously, interactive design has significant effects on social atmosphere and structure design has significant effects on interpersonal interaction.

The City

The Smart City program has become a step towards the development of digital space in the urban environment of megacities such as Moscow. Despite the global nature of the idea of the communicative-digital urban model, an attempt at a human-oriented approach remains. In the digital space, the function of anthropocentrism is assumed by interactive design that serves as an adaptation of the manifold urban environment. Design becomes a tool creating a person's comfort zone, implementing various urban socio-cultural scenarios interactively, taking into account the psycho-emotional state of a person. In the developed concept of WATT interactive application a person acts as an energetic and emotional "component" of the city. The product answers the goal of the design system of the sensual stratum of the environment, forming the concept of a Sensitive city and its important parameter: an indicator mood of the urban environment’s mood. The innovative character of the approach lies on the city aimed at the creation of an new energetical product - a tool that forms the eco-energy exchange between the resident and the city, results as an index of resident’s "happiness". The application becomes an example of the hybrid existence of urban environment, harmonizes the relationship between the digital field and the citizen: it supports the emotional and psychological state and offers various rehabilitation programs. This becomes especially relevant due to the need to neutralize the consequences of self-isolation after the pandemic.
