“…Usability questionnaires play an important role in usability testing, along with other quantitative and qualitative methods [ 32 , 35 , 39 ]. Although a few usability questionnaires have been developed [ 49 , 50 ] and validated [ 45 , 48 ] for European Portuguese, there is no specific instrument for the evaluation of medical devices’ usability. Facing this, a new usability questionnaire was developed, and a pilot validation study was conducted.…”

“…Some usability questionnaires have been validated and developed for European Portuguese, such as the System Usability Scale (SUS) for products and users’ interfaces usability [ 44 , 45 ], as well as the Post-Study System Usability Questionnaire (PSSUQ) for system usability [ 46 , 47 , 48 ]. Moreover, a Usability Scale was developed based on the International Classification of Functioning, Disability and Health (ICF), the ICF-Usability Scale (ICF-US), specifically as part of a comprehensive framework for the design, development, and evaluation of ambient assisted living products and services for older adults [ 49 , 50 ]. However, in Portugal, there is a lack of standardized and validated usability measures specifically validated or developed for the assessment of medical devices’ usability in their development process.…”

Background: Flushing a venous access device is an important procedure to maintain their patency and prevent malfunctioning and complications. An innovative double-chamber syringe was developed, allowing for the assessment of catheter patency, drug delivery and final flush. This study aims to assess the usability of this new device, considering three development stages (concept, semi-functional prototype, functional prototype). Methods: An iterative methodology based on a mix-method design (qualitative and quantitative) enabled the assessment of the devices’ usability by their primary end-users. A usability questionnaire was developed and applied, along with focus groups and individual interviews to nurses. Results: The usability questionnaire integrated 42 items focused on four dimensions (usefulness; ease of use; ease of learning; satisfaction and intention to use). The initial psychometric findings indicate a good internal consistency and the conceptual relevance of the items. The scores seem to be sensitive to the usability evaluation of the medical devices in different stages of product development (with lower values on functional prototype evaluation), and related to nurses’ perceptions about functional and ergonomic characteristics. Conclusions: Quantitative and qualitative data provided a comprehensive overview of the double-chamber syringes’ usability from the nurses’ point of view, informing us of features that must be addressed.

Le numérique ne cesse de se développer, notamment à l’école où les politiques éducatives en ont fait un des leviers de recherche prioritaires. Une utilisation efficace des technologies numériques éducatives est essentielle pour que les élèves puissent atteindre des objectifs d’apprentissages. Ainsi, il est important de pouvoir recueillir les perceptions des principaux utilisateurs que sont les enseignants et les élèves sur l’utilisabilité de ces nouvelles technologies en classe. Or, à notre connaissance, il n'existe pas encore de questionnaire d'évaluation de l'utilisabilité des interfaces numériques en français spécifiquement adapté aux jeunes élèves. K-Uses est une échelle de mesure d'évaluation de la perception de l'utilisabilité par les jeunes utilisateurs. Cette échelle de mesure repose sur le modèle présenté dans la norme ISO 9241-11 à laquelle nous avons ajouté le critère de « learnability » de Nielsen. Cet article présente la construction et les premiers éléments de validation du K-Uses avec des enfants âgés de 9 à 11 ans. La méthode utilisée a consisté en un examen de questionnaires d'utilisabilité existants, des prétests auprès d’enseignants et d’élèves auxquels ont participé trois évaluateurs et une analyse exploratoire des données recueillies auprès de 127 élèves. Les résultats sont prometteurs et montrent des niveaux satisfaisants de validité et de fiabilité.

“…less specific terminology, difficulty grasping an abstract concept, willingness to discuss with an adult [3,28]). Even with alternative solutions such as oral, written and pictorial methods (see examples [40,47]), because of these limitations children can have difficulty understanding, expressing their perceptions of the usability of an object or a system, and also being actively engaged in the rating task. Consequently, several studies have focused on finding a child-friendly scale format to measure children's judgments in a better way [22,47,59].…”
