Mobile web application for use in the Extended Family Health and Primary Care Center: content and usability validation

Abstract

Purpose: to validate the content and usability of the “Network NASF” application, intended for the teams of the Extended Family Health and Primary Care Center (NASF-AB). Methods: eighteen specialists, researchers, and professionals from different fields of study participated to validate the content and usability of the application, carried out in four stages: adjustment of the instrument; administration of the Suitability Assessment of Materials (SAM); validation of the content by calculating the content validity index (CVI); and usability evaluation through the System Usability Scale (SUS), in this order. Results: the participants classified the material as valid regarding both its content and usability. The index achieved in the SAM was 83.5%, as four, out of the six topics in the instrument, had values over 0.78. Hence, these four were considered excellent, while the other two were considered good. The recommendations given by the specialized judges were accepted and the usability index (5.5%) was considered relevant. Conclusion: the application developed for NASF-AB professionals was considered valid regarding its content and usability.
