What do the theories of reasoned action/planned behavior focus on?

The theories of reasoned action and planned behavior primarily emphasize the connection between intentions and behaviors. These theories suggest that an individual's behavioral intentions are the best predictors of actual behavior. This is based on the premise that when people intend to engage in a particular behavior, they are more likely to do so, provided they have a favorable attitude toward the behavior and perceive social norms that support it.

In this context, intentions are shaped by personal attitudes about the behavior as well as subjective norms, meaning the views of others or societal expectations. While factors like cognitive biases or environmental stimuli can influence behavior, the central tenet of these theories is that intentions serve as the crucial bridge between what individuals plan to do and what they ultimately execute. Understanding this theoretical framework helps in predicting and influencing health-related behaviors by targeting factors that shape intention.
