The Health Belief Model explains health behaviours through perceived threat and personal efficacy

Perceived susceptibility is your belief about whether you are at risk for a health problem.
Perceived severity is your belief about how serious the health problem would be if you got it.
Perceived benefits is your belief that the recommended action will reduce risk.
Perceived barriers are obstacles that prevent behaviour change, including cost, inconvenience, and side effects.
Cues to action are internal (symptoms) or external (health campaigns, social influence) triggers that prompt behaviour change.

Common Mistake

The Health Belief Model assumes people make rational decisions based on beliefs, but health decisions are often irrational, habitual, or driven by emotions rather than logical cost-benefit analysis.

Example

Someone might avoid vaccinations despite high perceived severity because perceived barriers (fear of needles, inconvenience, belief in side effects) outweigh perceived benefits.

Locus of control shapes whether you believe your health is within your power
