Health Belief Model

• Health Belief Model -> perceived seriousness, perceived susceptibility, cost-benefit analysis.
• Perceived seriousness -> change depends on how we perceive outcomes of not changing.
• Perceived susceptibility -> only change if we see ourselves as realistically vulnerable to illness.
• Cost-benefit analysis -> balance of perceived benefits and perceived barriers.
• Cues to action -> internal and external cues trigger change.
• Evaluation of health belief model (positives) -> practical uses, strong credibility.
• Evaluation of health belief model (negatives) -> model assumes people make rational decisions.
