The constructs attitudes, subjective norms, and perceived behavioral control are part of which theory/model?

The constructs of attitudes, subjective norms, and perceived behavioral control are integral components of the Theory of Planned Behavior. This theory posits that an individual's intention to engage in a behavior is influenced by their positive or negative evaluation of the behavior (attitudes), their perception of social pressure to perform or not perform the behavior (subjective norms), and their perceived control over the behavior (perceived behavioral control).

These constructs work together to provide a comprehensive understanding of why individuals choose to act in certain ways. For instance, if a person has a positive attitude towards healthy eating, believes that important people in their life support this behavior, and feels capable of making healthy food choices, they are more likely to intend to and ultimately engage in healthy eating.

In comparison, other options like the Health Belief Model focus on individual perceptions of health risks and benefits, the Transtheoretical Model deals with stages of change in behavior modification, and Social Cognitive Theory emphasizes observational learning and reinforcement. Therefore, the focus on attitudes, norms, and behavioral control distinctly identifies the Theory of Planned Behavior.
