Method: The questionnaire was applied to a sample of 1,247 full-time workers who work for a company that offers coffee and food in Mexico, in September and October 2019. The Results confirm that the 5 Categories comply with a minimum Cronbach's Alpha of .70, but do not meet the construct validity criteria derived from an Exploratory Factor Analysis and a Confirmatory Factor Analysis, in accordance with the requirements of numeral 7.5 of NOM-035, which must be observed by the work centers that decide to apply their own questionnaire. Limitation: This is a study that requires replication in order to confirm the results. Originality; In the literature it would be the second study that evaluates the reliability and validity of the survey. Findings: consequently, it is recommended to review the theoretical conceptualization of the Psychosocial Factors involved and the design of the questionnaire.
