Rosenstock's Health Belief Theory emphasizes the significance of individual perception in understanding health threats. This theory posits that a person's beliefs about their susceptibility to a health issue, the severity of the issue, the benefits of taking preventive action, and the barriers to taking that action are critical in shaping their health behaviors. The individual's perception drives their motivation to engage in health-promoting behaviors or preventive measures.

For example, if someone perceives themselves as being at high risk for a particular disease and believes the consequences of that disease are severe, they are more likely to take preventive actions, such as getting vaccinated or changing their lifestyle. Therefore, the theory serves as a framework for understanding why people do or do not engage in health-related behaviors based on their perceptions, rather than solely on external factors like genetic predisposition, environmental influences, or broader social determinants.
