In recent years, the study of psychosocial factors at work and their consequences regarding workers’ performance and health has increased in developed countries, nevertheless, in Mexico as in other Latin American countries (developing) the subject has been overlooked.
Some existing models of scientific interest have explained the process of stress as well as some of the conditions that cause it. Among the most well-known models are NIOSH’s Stress model; Karasek’s Demand-Control-Social Support model; and Siegrist’s Effort-Reward Imbalance (ERI) model. All these models share a vision of stress in terms of the relationship between work and the person. In agreement with this visualization, stress and the possibility of stress related diseases are produced when physical and psychological demands are not equal to the worker’s expectations, knowledge and capacities.
