Final answer:
According to the health belief model, in order to make a decision to change, the belief that the threat of illness outweighs the benefit of the healthy behavior, the perception of an increased susceptibility to an illness, and the ability to eliminate barriers must be present.
Step-by-step explanation:
According to the health belief model, in order to make a decision to change, the following must be present:
- The belief that the threat of illness outweighs the benefit of the healthy behavior.
- The perception of an increased susceptibility to an illness.
- The ability to eliminate barriers before engaging in a healthy behavior.
Let's break down each option:
- Believing that the threat of illness outweighs the benefit of the healthy behavior is important because it helps individuals understand the potential risks and consequences of not making a change.
- Perceiving an increased susceptibility to an illness motivates individuals to take action to protect themselves, as they recognize their vulnerability.
- The ability to eliminate barriers is crucial because it allows individuals to remove obstacles that may hinder them from engaging in the healthy behavior.
Overall, all three factors are necessary for an individual to make a decision to change according to the health belief model.
