History
The Health Belief Model is one of the first theories of health behavior.
It was developed in the 1950s by a group of U.S. Public Health Service social psychologists.
Works well for addressing problem behaviors that evoke health concerns.
HBM
HBM is a value-expectancy theory
Based on these assumptions:◦ People desire to avoid illness or get well◦ People believe that a specific health action that is
available to him or her will prevent illness
Readiness to Take Action = Perceived Threat
Readiness to Change Behavior = Perceived Benefit of Taking Action ◦ Cost-Benefit Analysis
Perceptions
1.) The severity of a potential illness
2.) The person's susceptibility to that illness
3.) The benefits of taking a preventive action
4.) The barriers to taking that action.
