What is the difference between the Theory of Reasoned Action and Theory of Planned Behavior?
The theory of reasoned action (TRA) is a special case of the theory of planned behavior (TPB). The only difference between the two theories is that the TPB includes behavioral control as an additional determinant of intentions and behavior.
What is the relationship between the Theory of Reasoned Action and health Behaviours?
Two closely associated theories – The Theory of Reasoned Action and the Theory of Planned Behavior – suggest that a person’s health behavior is determined by their intention to perform a behavior.
What does the Theory of Reasoned Action say?
The Theory of Reasoned Action (Fishbein and Ajzen, 1970, 1980) This theory assumes behaviour results from the intention to perform that behaviour. People decide their intention in advance of most voluntary behaviours, and intentions are the best predictors of what people will do.
Why is theory of planned Behaviour better than theory of reasoned action?
As expected, the theory of planned behavior permitted more accurate prediction of intentions and goal attainment than did the theory of reasoned action. In both experiments, perceived behavioral control added significantly to the prediction of intentions.
What is the example of theory of planned Behaviour?
For example, teenagers who smoke are usually are part of a peer group who smoke, therefore they might think smoking is the norm however most teenagers don’t smoke, so exposure to statistics showing them the true extent of smoking should change their subjective norm. TPB is the model most used in health psychology.
What are the components of the theory of planned Behaviour?
The theory of planned behavior (TPB) is a psychological theory that links beliefs to behavior. The theory maintains that three core components, namely, attitude, subjective norms, and perceived behavioral control, together shape an individual’s behavioral intentions.
