Which of the following is a key aspect of the Theory of Reasoned Action?

The Theory of Reasoned Action emphasizes the role of social norms and attitudes in shaping an individual's intentions and behaviors. It posits that a person's behavior is directly influenced by their beliefs about the outcomes of that behavior and the perceptions of social norms related to that behavior. Essentially, if individuals believe that their peers approve of a behavior and they have a positive attitude toward it, they are more likely to intend to perform that behavior.

This theory serves as a framework for understanding how personal beliefs and social influences can impact decision-making, particularly in the context of health behaviors. Social norms refer to the accepted standards within a group, which can significantly affect an individual's choices. Attitudes involve personal evaluations of the behavior, whether they see it as positive or negative.

While other options, like knowledge of health risks or government policies, may play a role in influencing behaviors, they do not capture the core principle of the Theory of Reasoned Action which focuses specifically on social norms and personal attitudes and how these directly affect behavioral intentions.
