(2025) System usability scale for gamified e-learning courses: cross-cultural adaptation and measurement properties of the Spanish version. International Journal of Human-Computer Interaction, 1-11. https://doi.org/10.1080/10447318.2025.2499947.1044-731810.1080/10447318.2025.2499947https://academica-e.unavarra.es/handle/2454/54468This study aimed to translate and culturally adapt the System Usability Scale for Gamified E-learning Courses (SUS-G scale) to the Spanish population and evaluate its factor structure. A cross-sectional study was conducted in two phases: translation and cultural adaptation of the SUS-G scale, followed by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), with 103 and 201 participants, respectively. A total of 304 students were enrolled in the study. The EFA revealed three correlated factors: User Experience (16 items), Educational Usability (nine items), and Usability (four items). The 29-item structure showed adequate-to-excellent goodness-of-fit indices and good internal consistency in CFA. The Spanish version of the SUS-G was validated and found to be reliable. The final instrument, with 29 items across three dimensions, can assess the usability of gamified e-learning courses among Spanish-speaking university students.application/pdfapplication/mswordeng© 2025 The Author(s).
