Theory of Planned Behavior - an overview | ScienceDirect Topics

Theory of Planned Behavior - an overview | ScienceDirect Topics: The Theory of Planned Behavior (TPB) postulates that the likelihood of an individual engaging in a health behavior (for example, regular exercise) is correlated with the strength of his or her intention to engage in the behavior. A behavioral intention represents an individual's commitment to act and is itself the outcome of a combination of several variables. According to the TPB, the factors that directly influence intentions to engage in a health behavior include the person's attitudes toward the behavior, the person's perception of subjective group norms concerning the behavior, and the extent to which the person perceives him- or herself to have control concerning the behavior (Fishbein, 2002).
