Morrison, D. L., Ou, D. and Roberts, D. (1987): Job Design and Levels of Physical and Mental Strain among Prison Officers. In: Proceedings of the Human Factors Society 31st Annual Meeting 1987. pp. 340-344.

“In this paper the preliminary results of a four year longitudinal study concerned with job design and levels of strain among a population of Prison Officers are reported. The job design factors that were studied related to perceived demands, constraints and supports. It was hypothesized that (i) those officers who perceive themselves as having jobs high in demand and level of constraint would suffer more strain than those of equal demand but who had a greater decision latitude (i.e., fewer constraints). It was further hypothesized that (ii) those in highly demanding and constrained jobs would show fewer strain symptoms if the environment in which they worked was perceived as providing social support. Preliminary analysis of the data shows that the first hypothesis was not supported for a measure of general physical well-being. However, there was evidence that those working in high security prisons showed significantly lower levels of general physical health than those working in low security environments. For measures of psychological well-being both hypotheses (i) and (ii) were partially supported. Those who perceived themselves as having high levels of support were found to suffer less from anxiety and depression. These effects were most apparent in the higher security prisons. Additional analyses have shown that the demands supports and constraints model is probably too simplistic and that other variables (e.g., personality) and further refinements to the model would help to account for additional variance in the measures of strain.”
