In the present article we studied the psychometric properties of the EL-Bus-21 scale, which enables us to evaluate the occupational stressors that affect Spanish bus drivers. 287 bus drivers (80.1% men and 19.9% women) took part in the study from three different sectors: metropolitan, intercity and charter coach drivers. The findings, after carrying out an exploratory factor analysis of the scale, revealed a structure comprised of three factors, namely, road environment, workload and fatigue, and personal discomfort. What's more, these three factors showed appropriate reliability. Similarly, the three factors showed validity with regard to stress, psycho-physiological disorders, safety behaviours in the vehicle and autonomy on the job as well as a number of empirical correlates. By way of summing up, the present scale may be ideally suited to adequately identifying the occupational stressors of Spanish bus drivers. The ELBus-21 may be used as a screening inventory in combination with other instruments.
