It is clear that some of the working conditions that characterize nursing may be implicated in stress-related issues. two of the most influential theories commonly used in studying work-related stress are the demands-control-support model and the effort-reward imbalance. both models have been found to predict many physical and psychological health outcomes, including mortality, heart disease, and depression and have also been used in nursing population.
the dcs model predicts that those exposed to high levels of psychological demand, and low levels of social support, and job control(from the sub-factors of decision authority and skill discretion)are likely to suffer negative health outcomes
