Final answer:
The Theory of Planned Action includes a perceived control component which represents an individual's belief in their ability to influence outcomes.
Step-by-step explanation:
The Theory of Planned Action expands upon the Behavioral Intentions Model by including a perceived control component. In this context, 'perceived control' references an individual's belief in their ability to influence and direct outcomes, thereby affecting their attitudes and behaviors. Understanding this concept is critical, as it has been linked to a variety of favorable outcomes, such as better mental health and more effective stress management. It's an internal mechanism that is thought to play a crucial role in shaping behavior, especially when considering the influence of personal motivation on decision-making processes and action.
