Effort-reward imbalance at work and driving anger in an Australian community sample: is there a link between work stress and road rage?

Both workplace stress and road rage are reported to be on the increase. This study examined the effort-reward imbalance (ERI) model of work stress and its relationship with general anger and driving anger in a community sample of 130 Australian workers. It also examined international differences in driving anger, with Australian motorists reporting lower levels of driving anger than American motorists but higher levels than British motorists. Hierarchical multiple regressions confirmed ERI increased driving anger via the mediating variables of general anger and overcommitment; individuals suffering ERI may develop increased general anger or overcommitment, in turn increasing propensity to experience driving anger. Regressions also showed that overcommitment (but not general anger) moderated the effect of ERI on driving anger; ERI has a greater influence on increasing driving anger in individuals with high overcommitment at work. The results have considerable implications for the safety and emotional health of individuals who perceive an imbalance between their efforts and rewards at work, and overcommitted individuals may be at greater risk. The wider implications of the relationship between work stress, emotional well-being and driving anger in employees, along with the potential of driver education interventions, are discussed as public health issues.
