Brief Description of the Theory of Planned Behavior According to the theory of planned behavior (TPB), human behavior is guided by three kinds of considerations: beliefs about the likely consequences and experiences associated with the behavior (behavioral beliefs), beliefs about the normative expectations and behaviors of significant others (normative beliefs), and beliefs about the presence of factors that may facilitate or impede performance of the behavior (control beliefs).In their respective aggregates, behavioral beliefs produce a favorable or unfavorable attitude toward the behavior; normative beliefs result in perceived social pressure or subjective norm; and control beliefs give rise to perceived behavioral control or self-efficacy.The effects of attitude toward the behavior and subjective norm on intention are moderated by perception of behavioral control.As a general rule, the more favorable the attitude and subjective norm, and the greater the perceived control, the stronger should be the person's intention to perform the behavior in question.Finally, given a sufficient degree of actual control over the behavior, people are expected to carry out their intentions when the opportunity arises.Intention is thus assumed to be the immediate antecedent of behavior.To the extent that perceived behavioral control is veridical, it can serve as a proxy for actual control and contribute to the prediction of the behavior in question.The following figure is a schematic representation of the theory.
