Dr. Chang's research interests focus on applying behavioral science principles to occupational health and safety. Specifically, she is interested in examining how psychosocial factors and individual differences influence employee responses to environmental stressors, as well as their impact on the effectiveness of various health and safety interventions. For example, leadership and the quality of leader-subordinate relationships will have significant impact on how employees respond to stressors such as role ambiguity, conflict, and perceived politics. Additionally, they will influence the effectiveness of the interventions designed to promote occupational health and safety. Similarly, employee personality, such as conscientiousness and affectivity, will have significant impact on employee reactions to stressors and intervention effectiveness. While important, these psychosocial factors and individual differences have received only limited research attention. Dr. Chang's work extends the traditional approach to occupational health and safety and supports a more comprehensive framework.
