Health Belief Model Definition, Strengths And Weaknesses

The Health Belief Model (HBM) is a instrument that scientists use to try to predict well being behaviors. It was initially developed within the 1950s, and up to date within the 1980s.

Health Belief Model

The mannequin is predicated on the speculation that an individual’s willingness to alter their well being behaviors is primarily because of the following elements.

Perceived Susceptibility

People is not going to change their well being behaviors except they imagine that they’re in danger. For instance, those that don’t assume that they’re prone to buying HIV from unprotected intercourse are unlikely to make use of a condom. Young individuals who do not assume they’re prone to lung most cancers are unlikely to give up smoking.

Perceived Severity

The likelihood that an individual will change his/her well being behaviors to keep away from a consequence relies on how critical they contemplate the consequence to be. For instance, if you’re younger and in love, you might be unlikely to keep away from kissing your sweetheart on the mouth simply because they’ve the sniffles, and also you would possibly get their chilly.

On the opposite hand, you in all probability would cease kissing if it would offer you Ebola. Similarly, individuals are much less more likely to contemplate condoms once they assume STDs are a minor inconvenience. That’s why speak about secure intercourse elevated through the AIDS epidemic. The perceived severity elevated enormously.

Perceived Benefits

It’s troublesome to persuade individuals to alter a habits if there is not one thing in it for them. People do not need to quit one thing they get pleasure from if they do not additionally get one thing in return.

For instance, an individual in all probability will not give up smoking if they do not assume that doing so will enhance their life indirectly. A pair may not select to follow secure intercourse if they do not see the way it may make their intercourse life higher.

Perceived Barriers

One of the key causes individuals do not change their well being behaviors is that they assume that doing so goes to be arduous. Sometimes it is not only a matter of bodily problem, however social problem as nicely. Changing your well being behaviors can price effort, cash, and time.

For instance, If everybody out of your workplace goes out consuming on Fridays, it could be very troublesome to chop down in your alcohol consumption. If you assume that condoms are an indication of mistrust in a relationship, you might be hesitant to convey them up.


One of the very best issues in regards to the Health Belief Model is how realistically it frames individuals’s behaviors. It acknowledges the truth that typically wanting to alter a well being habits is not sufficient to really make somebody do it.

So, it incorporates two extra parts into its estimations about what it really takes to get a person to make the leap. These two parts are cues to motion and self-efficacy.

Cues to Action

Cues to motion are exterior occasions that immediate a want to make a well being change. They may be something from a blood strain van being current at a well being honest, to seeing a condom poster on a practice, to having a relative die of most cancers. A cue to motion is one thing that helps transfer somebody from desirous to make a well being change to really making the change.


Self-efficacy is a component that wasn’t added to the mannequin till 1988. Self-efficacy appears to be like at an individual’s perception of their capability to make a health-related change. It could seem trivial, however religion in your capability to do one thing has an infinite influence in your precise capability to do it.

Thinking that you’ll fail will nearly make sure that you just do. In reality, lately, self-efficacy has been discovered to be probably the most necessary elements in a person’s capability to efficiently negotiate condom use.
