What theoretical model predicts actions based on personal attitudes and social perceptions?

The Theory of Reasoned Action is a well-established framework that focuses on the relationship between individuals' beliefs, attitudes, intentions, and behaviors. This model posits that a person's performance of a behavior is determined by their intention to engage in that behavior, which in turn is influenced by two primary factors: their personal attitudes toward the behavior and their perceptions of social norms surrounding it.

Attitudes refer to the personal evaluation of the behavior—whether the individual views it favorably or unfavorably. Social perceptions, which include normative beliefs about the acceptability of the behavior within their social circle, also play a crucial role, as they influence how much weight individuals give to what others think when forming their intentions.

By integrating personal attitudes and social influences, the Theory of Reasoned Action provides a comprehensive understanding of why individuals choose to act in certain ways, making it particularly applicable in fields like health promotion, marketing, and social psychology. This model is ideal for predicting intentional behavior based on a combination of internal motivations and external social pressures.
