Expanding the theory of planned behavior: Incorporating additional variables and dual-process models

Theory of planned behavior (TPB)

This paper describes and reviews the Theory of Planned Behavior (TPB), focusing on empirical and theoretical evidence supporting the inclusion of six additional variables: belief salience measures, past behavior/habit, perceived behavioral control (PBC) versus self-efficacy, moral norms, self-identity, and affective beliefs. Each variable demonstrates growing empirical support for its inclusion in the TPB, alongside an understanding of its relationship with other TPB components, intentions, and behavior. The paper presents two avenues for expanding the TPB: firstly, integrating TPB into a dual-process model of attitude–behavior relationships; secondly, exploring volitional processes that determine how goal intentions lead to goal achievement.
