This thesis adopts an occupational health psychology approach to· investigate work stress in a sample of U.K. bus drivers in several depots; Three studies were formulated and conducted. Study 1 (N = 24), based on five focus groups - to examine work stressors drawing upon the experiences of bus drivers. Stressors related to, inter alia, hindrance to the running schedule and arrangement of shifts. The information, supplemented by a literature review, was used to develop ajob-specific stressor instrument. Study 2 (N = 186), centred on a survey of seven depots, used a questionnaire survey consisting of: Karasek's (1985) Job Demands/Control (IDC), Siegrist et aI's (2004) Effort-Reward Imbalance (BRI), social support, psychological and physical ill-health, and the newly developed stressor instrument. Outcome measures included intention to quit, work absence, bus vehicle accident rate, passenger complaints, and smoking/drinking levels. Analyses showed that high demands/low control predicted higher job strain (e.g., ill-health), as did higher effort/lower reward. Workload and fatigue was a major set of sy-essors. The ERI model demonstrated stronger predictive ability of the two stress models. Additionally, buffering effects of control and social support disappeared in high ERI conditions. In the third study (N = 246) of seven depots, a final questionnaire survey was administered, again using the ERI measure, combined with job satisfaction, driver coping behaviours, and bus driver orientation (in terms of safety or running schedule). Results indicated that ERI was related to reduced job satisfaction, more maladaptive driver coping behaviour, and greater driver orientation towards the running schedule. Job satisfaction was found to be important in the ERI - intention to quit relationship, and overcommitment - work absence/intention to quit relationship. Considered together, these studies provide strong evidence for the need for occupational stress to be managed. Stress research contributions, methodological limitations, and recommendations for industry are discussed.
