Final answer:
The example of an adolescent smoker thinking that lung cancer only happens to old people is an example of perceived susceptibility in the Health Belief Model.
Step-by-step explanation:
The example of an adolescent smoker thinking that lung cancer only happens to old people is an example of perceived susceptibility in the Health Belief Model.
The Health Belief Model suggests that individuals are more likely to take action to protect their health if they perceive themselves to be susceptible to a health problem. In this case, the adolescent smoker's belief that lung cancer only affects old people may lead them to underestimate their susceptibility to the disease, making them less likely to consider quitting smoking.
Educational programs need to emphasize the risk and seriousness of lung cancer in adolescent smokers to increase their perceived susceptibility and motivate them to quit smoking.
