What are the three primary factors that drive our intention to change a behavior according to the Theory of Planned Behavior?

The correct identification of the three primary factors in the Theory of Planned Behavior being attitude, social norms, and perceived control highlights the core components that influence an individual’s intention to change behavior.

Attitude refers to the individual’s overall evaluation of the behavior in question, including the perceived benefits and drawbacks. A positive attitude toward a behavior increases the likelihood of intention to change. Social norms encompass the perceived social pressures to engage or not engage in a behavior, which can significantly impact a person's decision-making process. Finally, perceived control relates to the individual’s beliefs about their own ability to enact the behavior. This aspect emphasizes the importance of self-efficacy—if someone believes they have control over a situation or the ability to perform the behavior, they are more likely to intend to change.

Understanding these components helps in designing effective health communication strategies and interventions that enhance motivation for behavior change. The other choices do include important concepts related to behavior change but do not encapsulate the essence of the Theory of Planned Behavior as accurately as the selected answer.
