Not for things like addiction/smoking cessation programs screenings. Health belief model: based on value expectancy theory, people behavior according to the anticipated or expected personal benefits an action is anticipated to provide. Ex: going to college, getting a routine physical, seeing a counselor after the death of a loved one. Core constructs of hbm: perceived susceptibility. Perception of personal risk for developing or contracting disease/condition based on behavior. Perception of risk is not always explanatory of behavior. Define population at risk and their risk levels. Personalize risk based on a person"s traits or behaviors. Perception or belief as to severity of disease/condition: perceived severity/seriousness. Usually based on knowledge, but could be based on culture, past experiences, societal norms, etc. Seriousness could also be in terms of effects on lifestyle or livelihood.
