    La carga mental de trabajo (CMT) representa el valor asignado al esfuerzo mental requerido para realizar las tareas. El objetivo de este estudio fue identificar evidencias de validez y confiabilidad de los instrumentos utilizados para medir la carga de trabajo mental en los últimos 10 años, a través de una revisión de la literatura. Se realizaron búsquedas en las bases de datos Scopus, Web Of Science, PsycNet, PubMed y en el portal de la BVS (2012-2021), en inglés, español y portugués. Se incluyeron un total de 145 artículos y se ubicaron 16 instrumentos para medir CMT. Los resultados demuestran el uso de información sobre las propiedades psicométricas de los instrumentos que se basan en conceptos y procedimientos estadísticos que no siempre son consistentes con la verificación de la estructura interna del constructo. La validez de la estructura interna de los instrumentos fue verificada en sólo cuatro estudios, con índices de confiabilidad satisfactorios, pero aún con el uso de conceptos y metodologías de tratamiento y análisis insatisfactorios. Existen, por tanto, desafíos metodológicos, técnicos y conceptuales en los procesos de medición de la carga mental de trabajo.

    Mental workload (MLC) represents the value attributed to the mental effort required to perform tasks. The aim of this study was to identify evidence of validity and accuracy of instruments used to measure mental workload in the last 10 years, through a literature review. Searches were conducted in Scopus, Web Of Science, PsycNet, PubMed and the VHL portal (2012-2021), in English, Spanish and Portuguese. A total of 145 articles were included, and 16 instruments for measuring the CMT were located. The results demonstrate the use of information about the psychometric properties of instruments that depart from statistical concepts and procedures that are not always consistent with the verification of the internal structure of the construct. The validity of the instruments' internal structure was verified in only four studies, with satisfactory reliability indices, but still with the use of unsatisfactory concepts and methodologies for treatment and analysis. There are, therefore, methodological, technical and conceptual challenges in the processes of measuring mental workload.
