The Health Belief Model (HBM) was developed in the 1950s and has been practiced because it is logical, well articulated and simple.

constructs of hbm
Constructs of HBM
  • Perceived susceptibility: refers to belief about the likelihood of getting a disease or condition
  • Perceived the severity: feeling about the seriousness of contracting an illness or if leaving it untreated
  • Level of perceived threat: a compound of the two above elementary constructs, influences in the likelihood of the action– an expectancy-value formulation
  • Cues to the action: events, symptoms experienced by the person or reminders provided by a credible source
  • Modifying factors: age, race, gender, knowledge
  • Expected net gain (perceived benefits): benefits of adopting the health protective behavior, it is also the result expectancy-value formation.

  • Self efficacy was introduced to the HBM in 1977 and we will learn in Chapter 8.
  • People will not try a new behavior unless they are confident that they can perform the behavior.

example 1 getting flu shot
Example 1: getting flu shot
  • Perceive the severity: how sick I will be if I get flu?
  • Perceive susceptibility: how likely I would get flu?
  • Cues to the actions: on TVs, radio

These constructs directly contribute to level of perceived threat

example 1 getting flu shot1
Example 1: getting flu shot
  • Modifying factors: time, financial cost…
  • Expected net benefits:
    • the benefits of getting flu shot (not likely to get flu, no days off from work, affect quality of other chores).
    • The modifying factorsinfluence the perception of threat and the expected net benefits, and these two constructs both directly influence the behavior change
example 2 screening for htn
Example 2: screening for HTN
  • Perceive the severity: complications (stroke, MI…)
  • Perceive susceptibility: prevalence of raised BP in people >25yo was about 40% (2008-WHO)
  • Cues to the actions: on TV, radio, posters at clinics
  • Modifying factors: age, lifestyle, time, financial cost…
  • Expected net benefits: maintain good health quality, prevent from getting the complications and disabilities.
