Materials and methods: the sample of this study consisted of 56 persons of both genders, obtained through a census of the staff of two faculties of a Chilean university, who answered the Subjective Mental Workload Scale and the psychosocial risks evaluation questionnaire. The reliability was verified by Cronbach alpha coefficient, for the validity of content, the scale was checked by ad hoc experts. Constructo validity was evaluated by factorial analysis with Varimax rotation, and the criterion validity was measured when the results of the scale were correlated with the validated instrument SUSESO-ISTAS 21. Results: the multidimensional structure of the scale was confirmed, with a suitable reliability (a=0.79), the criterion validity by factorial analysis, and the constructo validity by Pearson correlation. Conclusion: SMWS is indicated as a reliable and valid instrument to evaluate the Mental Workload Perception.
