What are the key components of the epidemiological theory? How does their interaction affect accident causation?
What will be an ideal response?
Epidemiology is the study of causal relationships between environmental factors and disease. The epidemiological theory holds that the models used for studying and determining these relationships can also be used to study causal relationships between environmental factors and accidents or diseases.
Figure 3-4 illustrates the epidemiological theory of accident causation. The key components are predispositional characteristics and situational characteristics. These characteristics, taken together, can either result in or prevent conditions that may result in an accident. For example, if an employee who is particularly susceptible to peer pressure (predisposition characteristic) is pressured by his co-workers (situational characteristic) to speed up his work, the result will be an increased probability of an accident.
