Which factor is considered the main determinant of intention in the Theory of Reasoned Action?

The main determinant of intention in the Theory of Reasoned Action is attitude. This theory posits that a person's intention to engage in a behavior is influenced primarily by their attitude toward that behavior, as well as the subjective norms surrounding it. An individual's attitude reflects their overall evaluation of the behavior, encompassing both emotional responses and beliefs about the outcomes of that behavior. When an individual has a positive attitude toward a behavior, they are more likely to intend to perform that behavior.

In this framework, attitudes can be shaped through various experiences or information, leading to the conclusion that a favorable view of the behavior correlates with a greater intention to act. This understanding is central to the Theory of Reasoned Action, as it underscores the role of personal belief systems in influencing behavior choices. Thus, attitude serves as the key predictor of intention, making it fundamental to grasping how decisions are made within this theoretical model.
