1393/2013 - Avaliação da usabilidade do Guia Alimentar Digital móvel segundo a percepção dos usuários Usability evaluation of a mobile Digital Food Guide according to users’perception
Introdução. O uso da tecnologia digital na forma de aplicativos para cuidados em saúde tem crescido; na área de nutrição estão disponíveis aplicativos com o propósito de levar à mudança de comportamento, auxiliando indivíduos a refletir sobre escolhas alimentares e identificar fragilidades na rotina alimentar. Objetivo. Avaliar a percepção dos usuários em relação à usabilidade do Guia Alimentar Digital (GAD), aplicativo para celular smartphone, com diretrizes sobre alimentação saudável. Métodos. Estudo transversal avaliou a percepção de usuários do aplicativo por meio de escala Likert, construída com 24 asserções organizadas em três dimensões de análise: 1. GAD como ferramenta intuitiva e auto-explicativa; 2. GAD como promotor de escolhas alimentares saudáveis; 3. GAD como promotor da transição para o peso adequado. O instrumento foi analisado quanto à confiabilidade pelo método split-half e validade em duas etapas. Resultados. Foram validadas 22 asserções; a confiabilidade foi de 0,93; a média de pontos das asserções em cada dimensão foi 3,10; dos 80 respondentes, 58,75% considerou positiva a implementação do GAD. Conclusão. O aplicativo apresenta boa usabilidade, segundo a percepção dos usuários, a considerar as análises das dimensões referentes ao seu desempenho.

Abstract:
Introduction. The use of digital technology in the form of applications for health care has been growing and is a way of facilitating the food record and consumption studies. Applications are now available for the purpose of behavior change, helping individuals to ponder over food choices and identify fragilities in their routine. Objective. To evaluate the user’s perception on the usability of the Digital Food Guide (DFG), a mobile smartphone application with guidelines on healthy eating. Methods. Cross-sectional study evaluated the user perception of the application through Likert scale, built with 24 assertions organized in three analysis dimensions: DFG as intuitive and self-explanatory tool, as a promoter of healthy food choices and as a promoter of the transition to the appropriate weight. The instrument was assessed as to its reliability through the split-half method and validity in two stages. Results. The 22 assertions were validated; the reliability was 0.93; the average of the assertions in each dimension was 3.10; among the 80 respondents, 58.75% considered the implementation of the DFG positive. Conclusion. The application has good usability as perceived by users, considering the dimensions analysis related to its performance.
