The Demand-Control model and work-related threats and violence: Short- and long-term associations

Abstract

BACKGROUND: Work-related violence and threats are frequent in human service sectors. Although previous studies have identified several psycho-social work environmental risk factors for work-related violence and threats, the research domain still remains mainly descriptive and non-theoretical in nature. OBJECTIVE: Using the Job-Demands-Control model we analysed the relationship between the psycho-social work environment and work-related threats and violence. METHOD: Using a two-wave (2011 and 2015) longitudinal study of 2678 participants, we analysed the main and interactive effects of quantitative demands and job control on exposure to work-related violence and threats. RESULTS: High work demands and low job-control were associated with elevated risk of work-related threats in 2011 and in 2015. The associations of work demands and job control and work-related violence were mixed. There were not statistically significant interaction effects between high demands and low job control on neither work-related violence nor threats. CONCLUSION: In sectors where work-related threats and violence are likely to occur, risk prevention may also require improving the work conditions for employees, more specifically by reducing work-demands and increasing job control for instance by differentiating between important and less important work demands and by implementing self-autonomous work-teams may be a way to increase job control.
