University of North Florida

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.
