The role of workload and driver coping styles in predicting bus drivers' need for recovery, positive and negative affect, and physical symptoms.

A survey was conducted on a sample of 159 Australian bus drivers to determine the extent to which workload and self-reported driver coping styles predicted their subjective health status. The model that was proposed incorporated the hours spent driving as a measure of workload, both adaptive and maladaptive driver coping styles, and self-report measures of need for recovery (i.e., fatigue), positive and negative affect (PA and NA), and physical symptoms. The results of hierarchical regression analyses revealed that the workload was a significant predictor of drivers' need for recovery, but not of their PA and NA nor of their physical symptoms. Need for recovery was in turn a significant predictor of PA and NA and of their physical symptoms, indicating that it mediates the influence of workload on PA and NA and physical symptoms. Two maladaptive coping strategies added to the prediction of need for recovery, as well as to the prediction of NA, even after controlling for the influence of need for recovery. One adaptive coping strategy added to the prediction of PA. Strategies for management of fatigue in bus drivers should focus on the assessment and remediation of maladaptive coping strategies which impact of drivers' need for recovery, which in turn predicts PA and NA and physical symptoms.
