(13 cards)
Who came up with the health belief model
Rosenstock ( 1966)
What is the health belief model?
Is a psychological theory that tries to explain why people do or don’t engage in healthy behaviour the model can be summed up in three questions that an individual may ask themselves
What are the three questions? An individual may ask themselves when it comes to the health belief model?
- how serious are the consequences?(perceived seriousness.)
- How am I to get the disease?(perceived susceptibility)
- What are the advantages versus disadvantages of taking this action?(cost. -benefit analysis which we up perceived benefits versus perceived barriers. )
What is perceived susceptibility?
How personally and realistically vulnerable am I to an illness?
Perceived seriousness
How harmful will the consequences be if I do not change my health?
Cost and benefit analysis
The perceived benefits must outweigh the perceived barriers.
What are demographic variables?
The HBM is influenced by demographic variables such as gender, age , ethnicity etc. this helps to explain why a person may change their behaviour while the other person does not.
What are cues to actions?
Can be internal e.g. pain or external e.g. advice from a doctor. These cues are crucial in shifting a person from thinking about changing their behaviour to actually doing it.
What is self efficacy?
A persons confidence in their ability to take necessary action
A key strength:
A key strength of the HBM is the practical application in promoting healthy behaviour a Such as increasing cancer screening uptake. This is a strength as it shows value in read world interventions .
Another strength if the HBM:
Is it’s strong credibility as it is developed by health professionals using real life experiences, making it widely accepted by both individuals and practitioner.
One weakness of the HBM…
Is that changes to the model like adding self-efficacy have been criticised suggesting it may no longer Bea clear single model.
Another weakness…
Is that the HBM assumes people make rational health decisions, but choices can be driven by emotion or habit, suggesting other psychological factors way be more influential.
