The health belief model (Rosenstock) is concerned with what people perceive or believe to be true about them-selves in relation to their health. This model is based on three components of individual perceptions of threat of a disease: (1) perceived susceptibility to a disease, (2) perceived seriousness of a disease, and (3) perceived beneﬁts of action.
Health Belief Model (Hochbaum, Rosenstock and Kegels) HBM theorizes that a person will take a health-related action if they feel a negative health condition can be avoided. They have a positive expectation of avoiding a negative health condition if they take the action, and they believe they can successfully complete the recommended health action. This theory applies to Extension educators in the health and nutrition fields.
