Health Belief Model: Definition & Examples (Easy Explanation)

The health belief model (HBM) is a psychological theory that explains why people choose to adopt or ignore health behaviors. It suggests that behavior change depends on factors like perceived severity of a health risk, perceived benefits of taking action, and barriers to making changes. For example, a person is more likely to quit smoking if they believe the risk of lung cancer is serious and that quitting is beneficial. The model is used in public health campaigns to encourage preventive healthcare behaviors.
