The primary psychological factor in the Theory of Planned Behavior is intention. This theory posits that behavior is primarily driven by an individual’s intention to perform that behavior. Intention is influenced by three core components: attitudes toward the behavior, subjective norms, and perceived behavioral control. When individuals have a strong intention to engage in a specific behavior, they are more likely to follow through with it.

Intention serves as the bridge between individual beliefs and actual behavior. For example, if a person believes that exercising can improve their health (attitude), understands that friends and family support this decision (subjective norms), and feels they have the resources and ability to exercise (perceived behavioral control), it is likely they will intend to engage in regular physical activity.

While other factors like self-image, peer influence, and cognitive dissonance can impact behavior and motivation, they serve more as secondary influences within the framework. Peer influence might shape subjective norms, and cognitive dissonance can arise when intentions and behaviors are misaligned. However, intention remains the central concept that the theory emphasizes as the primary driver of behavior.
