Análisis comparativo de la carga mental en el personal administrativo de la Facultad de Ingeniería de la UNACH

Mental workload is one of the main ergonomic risks in today's administrative environments, where psychosocial demands predominate. The objective of this research was to comparatively analyze the mental workload levels of the administrative staff at the Faculty of Engineering of the National University of Chimborazo (UNACH) using the NASA-TLX and SWAT methods, and to determine their relationship with sociodemographic variables. A quantitative, descriptive-correlational, non-experimental, cross-sectional study was conducted with the entire administrative staff (n = 10). Data were processed in SPSS V26 using the chi-square test and Cramér's V coefficient. The results showed a predominance of high mental workload in both instruments (NASA-TLX: 90.0%; SWAT: 60.0%); no statistically significant relationship was found with age or years of experience. These results highlight the importance of implementing psychosocial intervention measures.
