The theory of planned behavior, developed by Icek Ajzen, is a social cognitive theory that has guided a large majority of theory-based research on physical activity. The theory of planned behavior is an extension of the theory of reasoned action developed by Martin Fishbein and Icek Ajzen in 1975. Since its introduction over 25 years
The theory of planned behavior (TPB) is one of a class of related theories of behavior change. The theory was developed by Icek Ajzen (1985, 1991) as an extension of the theory of reasoned action (TRA; Fishbein & Ajzen 1975), itself a model of behavior change.

Both focus on the question of how to determine the likelihood that an individual will engage in a specific behavior. The theory of reasoned action exam-ines determinants of volitional

It has its roots in Martin Fishbein and Ajzen’s theory of reasoned action, which was developed in response to observed lack of correspondence between general
