The content was validated by experts, obtaining an overall Índice de Validade de Conteúdo(Content Validity Index) of 86.72%. The game was tested by occupational nurses, and its “usability” was validated by the System Usability Scale instrument, with an index of 83.89%, and the “knowledge improvement” by the EGameFlow instrument with a mean of 6.52.


the Expressing Milk Game technology obtained a high level of validity in terms of content and usability, demonstrating that it is an educational technology for health professionals to guide the maintenance of breastfeeding to nursing mothers.
