Stress prevention in bus drivers: Evaluation of 13 natural experiments.
研究通过分析13项国际公交公司的自然实验，评估了减少司机职业压力和病假的干预措施，发现结合工作导向和人员导向的干预可能对员工和企业都有益。
The research aim was to select, compare, and analyze interventions and preventive actions from international bus companies to decrease bus drivers' occupational stress and sickness absenteeism. Through networking, international surveys, and literature study, 13 "natural experiments" were identified with an acceptable research design rating. Interventions were both work and person directed. Principles of worker participation were often followed. The variety in intervention programs, outcome measures, case evaluations, and methodological flaws makes it difficult to present a general picture of program effectiveness. However, analyses on more objective and more subjective outcomes do point at positive effects. This study suggests that stress prevention that combines adequate interventions and proper implementation may be beneficial to both the employee and the company.
