Theory Of Planned Behavior/ Reasoned Action

 

Theory Of Planned Behavior/ Reasoned Action Ajzen and Fishbein formulated in 1980 the theory of reasoned action (TRA) after trying to estimate the discrepancy between attitude and behavior. The theory was called the theory of planned behavior (TpB). The theory of planned behavior is a theory which predicts deliberate behavior, because behavior can be deliberative and planned.

 

Core Assumptions and Statements:  Theory of Reasoned Action suggests that a person's behavior is determined by his/her intention to perform the behavior and that this intention is, in turn, a function of his/her attitude toward the behavior and his/her subjective norm. The best predictor of behavior is intention. 

Intention is the cognitive representation of a person's readiness to perform a given behavior, and it is considered to be the immediate antecedent (முன் நிகழ்ந்ததும் அதன் மீது தாக்கத்தை ஏற்படுத்தியிருக்கக் கூடியதுமான ஒன்று; )of behavior.

 

 This intention is determined by three things:

1. 1   their attitude toward the specific behavior,
2. 2.   their subjective norms and
3. 3.   their perceived behavioral control.

 

In addition to measuring attitudes toward the behavior, we also need to measure people’s

• subjective norms –
• their beliefs about how people they care about
• will view the behavior 

 

To predict someone’s intentions, knowing these beliefs can be as important as knowing the person’s attitudes. Finally, perceived behavioral control influences intentions. Perceived behavioral control refers to people's perceptions of their ability to perform a given behavior. These predictors lead to intention.

Favorite Methods Ajzen provides fairly clear instructions for designing theory of planned behavior questionnaires on his website.

 

Ajzen uses a questionnaire to define the elements of behavior and uses direct observation or self-reports later on. This theory is also used in evaluation studies.

Other usages of the model include:

• voting behavior,
• disease prevention behavior,
• birth control behavior (Jaccard & Davidson, 1972),
• consumption prediction.
•  

Example Examples of items which can be researched with the theory of planned behavior are whether to wear a seat belt.
