Comparison between the Theory of Planned Behavior and the Theory of Reasoned Action - Assignment Example

On the other hand, the TPB suggests that unique individual attitudes towards a given behavior predict the behavior in question. Two theories are built around the role of attitude in influencing a person’s intention to perform a certain behavior. These theories emphasize an individual attitude toward behavior and subjective norm as a key determinants of an individual’s intention to perform a given form of behavior. Although the TRA has been extended by Ajzen to include the concept of perceived behavioral control dubbed the theory of planned behavior (TPB), a distinction still exists between the two theories (Brannon & Feist, 2009).

The latter emphasizes the influence of perceived control over a given behavior as a key determinant of an individual’s behavior. The TPB purports that resources and opportunities available to an individual influence control over their behavior (Brannon & Feist, 2009). Conversely, the theory of reasoned behavior relies on self-efficacy as the other determinant of perceived control over an individual’s behavior. Self-efficacy is viewed as belief in the ability to perform behaviors that elicit desired outcomes, a phenomenon that influences a person’s intentions to engage in certain behavior. . Smith, R.
