Health Belief Model

  1. 1. HEALTH BELIEF MODEL Deblina Roy M.SC Nursing 1st year K.G.M.U. Institute of Nursing
  2. 2. Model • Model is a theoretical way of understanding concept or idea. •Health Beliefs: • These are person’s Ideas, convictions, attitudes about health and illness.
  3. 3. History of the HBM • Developed in the 50’s by the U.S. Public Health Service • Social psychologists were asked to explain why people do not participate in health behaviors (Rosenstock, 1960; 1966) • Developed based on operant and cognitive-behavioral theory
  4. 4. Premise of the Health Belief Model • Individuals will take action to ward off, to screen for, or to control an ill health condition if: • 1) they regard themselves as susceptible to the condition • 2) they believe it to have potentially serious consequences • 3) they believe a course of action can reduce the susceptibility and seriousness • 4) they believe the costs of the action are outweighed by its benefits
  5. 5. Components of the HBM • Perceived Susceptibility • an individual’s perception of her or his risk of contracting a health condition • Perceived Severity • an individual’s perception of the seriousness of a health condition if left untreated • Note: the combination of these is the perceived threat of the health condition (emotive response is fear)
  6. 6. Components of the HBM • Perceived Benefits • the perceived effectiveness of taking action to improve a health condition • Perceived Barriers • the perceived impediments to taking action to improve a health condition
  7. 7. Components of the HBM •Cues to Action • Body or environmental events that trigger the HBM
  8. 8. Additional Components? • Self-Efficacy • confidence to continue the healthy behavior and overcome temptations
  9. 9. Where Do We Intervene? • Educate about threat (vulnerability, susceptibility) • Fear appraisals • Educate about coping (response efficacy, self-efficacy) • Health education
  10. 10. Evaluating the HBM • APPLICABILITY TO PRACTICE (IS IT USEFUL?) • Coping efficacy is the most important component • Self-efficacy (and perceived barriers) is the most influential component for health behavior • Perceived severity is the weakest component • Health behaviors are long-term? • Perceived vulnerability often influences intentions but not behavior
  11. 11. Evaluating the HBM • COMPREHENSIVE (Does it explain behavior completely?) • No • What about other motives for behavior other than health? These motives appear untapped for explaining behavior.
  12. 12. Application Exercise • Please choose a health behavior and population • Assume you are an specialist contracted to develop a persuasive communication (poster, news advertisement etc.) to improve the health behavior for the population • Create a message that includes severity, susceptibility, response efficacy, and self-efficacy for the target population
  13. 13. Questions?
