          Abstract

          RESUMO Objetivo Avaliar a usabilidade e satisfação dos usuários com a interface do aplicativo “Agente Escuta”, além de identificar problemas e possibilidades de melhorias. Método Estudo translacional exploratório descritivo, caracterizado por um teste de usabilidade com abordagem quanti-qualitativa, subdividido em três etapas: (I) avaliação prévia da usabilidade por 10 juízes, incluindo estudantes, profissionais da atenção primária, docentes e pesquisadores em Tecnologia da Informação e Fonoaudiologia; (II) avaliação do aplicativo pelo público-alvo, agentes comunitários de saúde de seis municípios potiguares; (III) Avaliação da satisfação dos agentes que utilizaram o aplicativo na rotina de trabalho. Utilizou-se o System Usability Scale e pelo Net Promoter Score, além de uma avaliação qualitativa das opiniões. Resultados A usabilidade foi avaliada como excelente pelos juízes, independentemente da categoria. Na avaliação pelos agentes comunitários de saúde, a usabilidade foi considerada boa e não houve efeito do município de origem. Constatou-se que a percepção dos juízes e do público-alvo foram distintas, com menor escore para os participantes da segunda etapa, no entanto, a maioria dariam publicidade positiva ao produto. A heurística com maior pontuação foi a facilidade de memorização e os participantes da terceira etapa mostraram-se interessados em continuar utilizando a ferramenta na prática, mesmo após o término do estudo. Conclusão O protótipo do Agente Escuta apresentou boa usabilidade e satisfação e foram identificados aspectos que poderão ser aprimorados em soluções futuras.

          ABSTRACT Purpose To evaluate the usability and satisfaction of users with the interface of the ‘Agente Escuta’ application, in addition to identifying problems and possibilities for improvement. Methods Descriptive exploratory translational study, characterized by a usability test with a quantitative and qualitative approach, subdivided into three stages: (I) prior evaluation of usability by 10 judges, including students, primary care professionals, professors and researchers in Information Technology and Speech Therapy; (II) evaluation of the application by the target audience, that is, community health agents from six municipalities in Rio Grande do Norte; (III) evaluation of the satisfaction of the agents who used the application in their work routine. The System Usability Scale and the Net Promoter Score were used, in addition to a qualitative evaluation of the opinions. Results Usability was rated as excellent by judges, regardless of category. In the evaluation by community health agents, usability was considered good and there was no effect of the city of origin. It was found that the perception of the judges and the target audience were different, with a lower score for the participants in the second stage. However, most would give positive publicity to the product. The heuristic with the highest score was ease of memorization and participants in the third stage were interested in continuing to use the tool in practice, even after the end of the study. Conclusion The Agente Escuta prototype showed good usability and satisfaction and aspects that could be improved in future solutions were identified.

            The mHealth App Usability Questionnaire (MAUQ): Development and Validation Study

            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.
