Psychosocial work factors affecting safety incidents of long-distance bus drivers in Ghana: Mediating role of psychological well-being.

Background: Improving psychosocial work environment of long-distance bus drivers is essential for their psychological well-being and on-the-road safety. Despite the importance of the work environment of bus drivers, it has received little research attention in Ghana and other developing nations. Hence, this study examined the influence of psychosocial work factors (job demands and job resources) on safety incidents of long-distance bus drivers and how psychological well-being mediates this association. Methods: This cross-sectional survey sampled 7315 long-distance bus drivers who commute from the cities of Accra and Tema to other parts of Ghana and other cities in the West Africa sub-region. Partial least squares structural equation modelling (PLS-SEM) was used to test four hypotheses. Findings: The results suggest that job demands and job resources have direct association with safety incidents of the long-distance bus drivers. The psychological well-being of the bus drivers played a partial mediation role in the association between psychosocial work factors and safety incidents of the drivers. Conclusion: The job demand-resource model provides a useful model for understanding the impact of the work environment on driving performance among these long-distance bus drivers. Providing the drivers with high job control and supportive work culture can equip and support them to value the critical roles they play in the transport sector. Managers of bus transport companies and individual bus owners should implement effective communication strategies like the bottom-up communication approach, conduct periodic assessments to identify and address drivers' precarious work conditions, create safety on the road, and reduce crashes and associated fatalities.
