Abstract
In recent years a number of authors have suggested that progress towards a better understanding of the stressor-stress relationship can only be achieved by altering the way in which work stress is investigated. One strategy is to investigate what it is we are measuring when we assess work stressors. More particularly there is a need to use rating scales that measure demand associated with work roles rather than just imply it. Dimensions such as frequency, duration, and level of demand were measured in addition to the traditional method of simply asking individuals to indicate whether they agree/disagree that stressors are present at work. The results point to the incremental increase in variance explained when these additional facets are measured over and above the variance explained by traditional methods. This result confirms the ned to develop a better understanding of the concept of demand, the difference between chronic and acute stressors, and the interaction effects of the different facets.
