Results suggest that in the absence of specific organizational intervention aimed at improving a deleterious work situation, exposure to low decision latitude remained similar between 2002 and 2004, while exposure to high psychological demands improved somewhat, for both men and women. In 2000, rates of exposure of correctional officers in Quebec to high psychological demands, low decision latitude and the combination of high psychological demands and low decision latitude (job strain) were significantly higher than those obtained for the entire population of workers in Quebec in contact with the public. Exposure of correctional officers in Quebec to intimidation at work increased substantially between 2002 and 2004, among both men and women. Globally speaking, rates of exposure to intimidation by colleagues and superiors practically doubled between 2000 and 2004. Rates of exposure to intimidation among correctional officers in Quebec were particularly high in 2004 (71% among men 66% among women) compared to rates in another study conducted among federal correctional officers (48%) by Samak. The present study also showed that in 2004, correctional officers in Quebec were more likely to present signs of psychological distress linked with work when they were exposed to high psychological demands, low decision latitude, job strain and poor social support from superiors and colleagues. Psychological distress was also shown to be greater when reward at work was scarce and when there was an imbalance between effort and reward at work. Finally, in 2004, psychological distress among correctional officers was also associated with intimidation and psychological harassment at work.
